      public interface AmazonS3

  Provides an interface for accessing the Amazon S3 web service.

  Amazon S3 provides storage for the Internet, and is designed to make web-scale computing easier for developers.

  The Amazon S3 Java SDK provides a simple interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.

- - ### メソッドの詳細

    - #### setEndpoint

          void setEndpoint(java.lang.String endpoint)

      Overrides the default endpoint for this client. Use this method to send requests to the specified AWS region.

      Pass the endpoint (e.g. "s3.amazonaws.com") or a full URL, including the protocol (e.g. "https://s3.amazonaws.com"). If the protocol is not specified, the protocol from this client's `ClientConfiguration` is used.

      パラメータ:
        `endpoint` - The endpoint (e.g. "s3.amazonaws.com") or the full URL, including the protocol (e.g. "https://s3.amazonaws.com"), of the region-specific AWS endpoint this client will communicate with.
      例外:
        `java.lang.IllegalArgumentException` - If the specified endpoint is not a valid URL endpoint.

    - #### setRegion

          void setRegion(Region region)
                         throws java.lang.IllegalArgumentException

      An alternative to `setEndpoint(String)`, sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

      This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

      By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the `ClientConfiguration` supplied at construction.

      パラメータ:
        `region` - The region this client will communicate with. See `Region.getRegion(com.amazonaws.regions.Regions)` for accessing a given region.
      例外:
        `java.lang.IllegalArgumentException` - If the given region is null, or if this service isn't available in the given region. See `Region.isServiceSupported(String)`
      関連項目:
        `Region.getRegion(com.amazonaws.regions.Regions)`, `Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)`

    - #### setS3ClientOptions

          void setS3ClientOptions(S3ClientOptions clientOptions)

      Override the default S3 client options for this client.

      パラメータ:
        `clientOptions` - The S3 client options to use.

    - #### changeObjectStorageClass

          void changeObjectStorageClass(java.lang.String bucketName,
                                      java.lang.String key,
                                      StorageClass newStorageClass)
                                        throws AmazonClientException,
                                               AmazonServiceException

      Changes the Amazon S3 storage class for a specified object. Amazon S3 offers multiple storage classes for developers' different needs.

      Note that changing the storage class of an object in a bucket that has enabled versioning creates a new version of the object with the new storage class. The existing version of the object persists in the current storage class.

      パラメータ:
        `bucketName` - The name of the bucket containing the object.
        `key` - The key of the object within the specified bucket.
        `newStorageClass` - The new storage class for the specified object.
      例外:
        `AmazonClientException` - If any errors are encountered in the client while making the request or handling the response.
        `AmazonServiceException` - If any errors occurred in Amazon S3 while processing the request.

    - #### setObjectRedirectLocation

          void setObjectRedirectLocation(java.lang.String bucketName,
                                       java.lang.String key,
                                       java.lang.String newRedirectLocation)
                                         throws AmazonClientException,
                                                AmazonServiceException

      Changes the Amazon S3 redirect location for a specific object.

      パラメータ:
        `bucketName` - The name of the bucket containing the object.
        `key` - The key of the object within the specified bucket.
        `newRedirectLocation` - The new redirect location for the specified object.
      例外:
        `AmazonClientException` - If any errors are encountered in the client while making the request or handling the response.
        `AmazonServiceException` - If any errors occurred in Amazon S3 while processing the request.

    - #### listObjects

          ObjectListing listObjects(java.lang.String bucketName)
                                    throws AmazonClientException,
                                           AmazonServiceException

      Returns a list of summary information about the objects in the specified buckets. List results are always returned in lexicographic (alphabetical) order.

      Because buckets can contain a virtually unlimited number of keys, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the `ObjectListing.isTruncated()` method to see if the returned listing is complete or if additional calls are needed to get more results. Alternatively, use the `AmazonS3Client.listNextBatchOfObjects(ObjectListing)` method as an easy way to get the next page of object listings.

      The total number of keys in a bucket doesn't substantially affect list performance.

      パラメータ:
        `bucketName` - The name of the Amazon S3 bucket to list.
      戻り値:
        A listing of the objects in the specified bucket, along with any other associated information, such as common prefixes (if a delimiter was specified), the original request parameters, etc.
      例外:
        `AmazonClientException` - If any errors are encountered in the client while making the request or handling the response.
        `AmazonServiceException` - If any errors occurred in Amazon S3 while processing the request.

        `AmazonS3Client.listObjects(String, String)`, `AmazonS3Client.listObjects(ListObjectsRequest)`

    - #### listObjects

          ObjectListing listObjects(java.lang.String bucketName,
                                  java.lang.String prefix)
                                    throws AmazonClientException,
                                           AmazonServiceException

      Returns a list of summary information about the objects in the specified bucket. Depending on request parameters, additional information is returned, such as common prefixes if a delimiter was specified. List results are always returned in lexicographic (alphabetical) order.

      Because buckets can contain a virtually unlimited number of keys, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the `ObjectListing.isTruncated()` method to see if the returned listing is complete or if additional calls are needed to get more results. Alternatively, use the `AmazonS3Client.listNextBatchOfObjects(ObjectListing)` method as an easy way to get the next page of object listings.

      For example, consider a bucket that contains the following keys:

      - "foo/bar/baz"
      - "foo/bar/bash"
      - "foo/bar/bang"
      - "foo/boo"
      If calling `listObjects` with a `prefix` value of "foo/" and a `delimiter` value of "/" on this bucket, an `ObjectListing` is returned that contains one key ("foo/boo") and one entry in the common prefixes list ("foo/bar/"). To see deeper into the virtual hierarchy, make another call to `listObjects` setting the prefix parameter to any interesting common prefix to list the individual keys under that prefix.

      The total number of keys in a bucket doesn't substantially affect list performance.

      パラメータ:
        `bucketName` - The name of the Amazon S3 bucket to list.
        `prefix` - An optional parameter restricting the response to keys beginning with the specified prefix. Use prefixes to separate a bucket into different sets of keys, similar to how a file system organizes files into directories.
      戻り値:
        A listing of the objects in the specified bucket, along with any other associated information, such as common prefixes (if a delimiter was specified), the original request parameters, etc.
      例外:
        `AmazonClientException` - If any errors are encountered in the client while making the request or handling the response.
        `AmazonServiceException` - If any errors occurred in Amazon S3 while processing the request.

                                    throws AmazonClientException,
                                           AmazonServiceException

      Returns a list of summary information about the objects in the specified bucket. Depending on the request parameters, additional information is returned, such as common prefixes if a delimiter was specified. List results are always returned in lexicographic (alphabetical) order.

Alternatively, use the `AmazonS3Client.listNextBatchOfObjects(ObjectListing)` method as an easy way to get the next page of object listings.

      Calling `ListObjectsRequest.setDelimiter(String)` sets the delimiter, allowing groups of keys that share the delimiter-terminated prefix to be included in the returned listing. This allows applications to organize and browse their keys hierarchically, similar to how a file system organizes files into directories. These common prefixes can be retrieved through the `ObjectListing.getCommonPrefixes()` method.

      For example, consider a bucket that contains the following keys:

      - "foo/bar/baz"
      - "foo/bar/bash"
      - "foo/bar/bang"
      - "foo/boo"
      If calling `listObjects` with a prefix value of "foo/" and a delimiter value of "/" on this bucket, an `ObjectListing` is returned that contains one key ("foo/boo") and one entry in the common prefixes list ("foo/bar/"). To see deeper into the virtual hierarchy, make another call to `listObjects` setting the prefix parameter to any interesting common prefix to list the individual keys under that prefix.

      The total number of keys in a bucket doesn't substantially affect list performance.

      パラメータ:
        `listObjectsRequest` - The request object containing all options for listing the objects in a specified bucket.
      戻り値:
        A listing of the objects in the specified bucket, along with any other associated information, such as common prefixes (if a delimiter was specified), the original request parameters, etc.

                                                      AmazonServiceException

      Provides an easy way to continue a truncated object listing and retrieve the next page of results.

      To continue the object listing and retrieve the next page of results, call the initial `ObjectListing` from one of the `listObjects` methods. If truncated (indicated when `ObjectListing.isTruncated()` returns `true`), pass the `ObjectListing` back into this method in order to retrieve the next page of results. Continue using this method to retrieve more results until the returned `ObjectListing` indicates that it is not truncated.

      パラメータ:
        `previousObjectListing` - The previous truncated `ObjectListing`. If a non-truncated `ObjectListing` is passed in, an empty `ObjectListing` is returned without ever contacting Amazon S3.
      戻り値:
        The next set of `ObjectListing` results, beginning immediately after the last result in the specified previous `ObjectListing`.
      例外:
        `AmazonClientException` - If any errors are encountered in the client while making the request or handling the response.
        `AmazonServiceException` - If any errors occurred in Amazon S3 while processing the request.

                                             AmazonServiceException

      Returns a list of summary information about the versions in the specified bucket.

      The returned version summaries are ordered first by key and then by version. Keys are sorted lexicographically (alphabetically) while versions are sorted from most recent to least recent. Both versions with data and delete markers are included in the results.

      Because buckets can contain a virtually unlimited number of versions, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the `VersionListing.isTruncated()` method to determine if the returned listing is complete or if additional calls are needed to get more results. Callers are encouraged to use `listNextBatchOfVersions(VersionListing)` as an easy way to get the next page of results.

      For more information about enabling versioning for a bucket, see `setBucketVersioningConfiguration(SetBucketVersioningConfigurationRequest)`.

      パラメータ:
        `bucketName` - The name of the Amazon S3 bucket whose versions are to be listed.
        `prefix` - An optional parameter restricting the response to keys beginning with the specified prefix. Use prefixes to separate a bucket into different sets of keys, similar to how a file system organizes files into directories.
      戻り値:
        A listing of the versions in the specified bucket, along with any other associated information and original request parameters.

      Provides an easy way to continue a truncated `VersionListing` and retrieve the next page of results.

      Obtain the initial `VersionListing` from one of the `listVersions` methods. If the result is truncated (indicated when `ObjectListing.isTruncated()` returns `true`), pass the `VersionListing` back into this method in order to retrieve the next page of results. From there, continue using this method to retrieve more results until the returned `VersionListing` indicates that it is not truncated.

      For more information about enabling versioning for a bucket, see `setBucketVersioningConfiguration(SetBucketVersioningConfigurationRequest)`.

      パラメータ:
        `previousVersionListing` - The previous truncated `VersionListing`. If a non-truncated `VersionListing` is passed in, an empty `VersionListing` is returned without ever contacting Amazon S3.
      戻り値:
        The next set of `VersionListing` results, beginning immediately after the last result in the specified previous `VersionListing`.
      例外:

      Returns a list of summary information about the versions in the specified bucket.

      The returned version summaries are ordered first by key and then by version. Keys are sorted lexicographically (alphabetically) and versions are sorted from most recent to least recent. Versions with data and delete markers are included in the results.

      Because buckets can contain a virtually unlimited number of versions, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Always check the `VersionListing.isTruncated()` method to determine if the returned listing is complete or if additional calls are needed to get more results. Callers are encouraged to use `listNextBatchOfVersions(VersionListing)` as an easy way to get the next page of results.

      The `keyMarker` and `versionIdMarker` parameters allow callers to specify where to start the version listing.

      The `delimiter` parameter allows groups of keys that share a delimiter-terminated prefix to be included in the returned listing. This allows applications to organize and browse their keys hierarchically, much like how a file system organizes files into directories. These common prefixes can be retrieved by calling the `VersionListing.getCommonPrefixes()` method.

      For example, consider a bucket that contains the following keys:

      - "foo/bar/baz"
      - "foo/bar/bash"
      - "foo/bar/bang"
      - "foo/boo"
      If calling `listVersions` with a `prefix` value of "foo/" and a `delimiter` value of "/" on this bucket, a `VersionListing` is returned that contains:
      - all the versions for one key ("foo/boo")
      - one entry in the common prefixes list ("foo/bar/")

      To see deeper into the virtual hierarchy, make another call to `listVersions` setting the prefix parameter to any interesting common prefix to list the individual versions under that prefix.

      For more information about enabling versioning for a bucket, see `setBucketVersioningConfiguration(SetBucketVersioningConfigurationRequest)`.

      パラメータ:
        `bucketName` - The name of the Amazon S3 bucket whose versions are to be listed.
        `prefix` - An optional parameter restricting the response to keys that begin with the specified prefix. Use prefixes to separate a bucket into different sets of keys, similar to how a file system organizes files into directories.
        `keyMarker` - Optional parameter indicating where in the sorted list of all versions in the specified bucket to begin returning results. Results are always ordered first lexicographically (i.e. alphabetically) and then from most recent version to least recent version. If a keyMarker is used without a versionIdMarker, results begin immediately after that key's last version. When a keyMarker is used with a versionIdMarker, results begin immediately after the version with the specified key and version ID.

        This enables pagination; to get the next page of results use the next key marker and next version ID marker (from `VersionListing.getNextKeyMarker()` and `VersionListing.getNextVersionIdMarker()`) as the markers for the next request to list versions, or use the convenience method `listNextBatchOfVersions(VersionListing)`

        `versionIdMarker` - Optional parameter indicating where in the sorted list of all versions in the specified bucket to begin returning results. Results are always ordered first lexicographically (i.e. alphabetically) and then from most recent version to least recent version. A keyMarker must be specified when specifying a versionIdMarker. Results begin immediately after the version with the specified key and version ID.

        This enables pagination; to get the next page of results use the next key marker and next version ID marker (from `VersionListing.getNextKeyMarker()` and `VersionListing.getNextVersionIdMarker()`) as the markers for the next request to list versions, or use the convenience method `listNextBatchOfVersions(VersionListing)`

        `delimiter` - Optional parameter that causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the `VersionListing.getCommonPrefixes()` list. These rolled-up keys are not returned elsewhere in the response. The most commonly used delimiter is "/", which simulates a hierarchical organization similar to a file system directory structure.
        `maxResults` - Optional parameter indicating the maximum number of results to include in the response. Amazon S3 might return fewer than this, but will not return more. Even if maxKeys is not specified, Amazon S3 will limit the number of results in the response.
      戻り値:
        A listing of the versions in the specified bucket, along with any other associated information such as common prefixes (if a delimiter was specified), the original request parameters, etc.

      Creates a new Amazon S3 bucket in the default region, `Region.US_Standard`.

      Every object stored in Amazon S3 is contained within a bucket. Buckets partition the namespace of objects stored in Amazon S3 at the top level. Within a bucket, any name can be used for objects. However, bucket names must be unique across all of Amazon S3.

      Bucket ownership is similar to the ownership of Internet domain names. Within Amazon S3, only a single user owns each bucket. Once a uniquely named bucket is created in Amazon S3, organize and name the objects within the bucket in any way. Ownership of the bucket is retained as long as the owner has an Amazon S3 account.

      To conform with DNS requirements, the following constraints apply:

      - Bucket names should not contain underscores
      - Bucket names should be between 3 and 63 characters long
      - Bucket names should not end with a dash
      - Bucket names cannot contain adjacent periods
      - Bucket names cannot contain dashes next to periods (e.g., "my-.bucket.com" and "my.-bucket" are invalid)
      - Bucket names cannot contain uppercase characters

      There are no limits to the number of objects that can be stored in a bucket. Performance does not vary based on the number of buckets used. Store all objects within a single bucket or organize them across several buckets.

      Buckets cannot be nested; buckets cannot be created within other buckets.

      Do not make bucket create or delete calls in the high availability code path of an application. Create or delete buckets in a separate initialization or setup routine that runs less often.

                            java.lang.String region)
                              throws AmazonClientException,
                                     AmazonServiceException

      Creates a new Amazon S3 bucket with the specified name in the specified Amazon S3 region. This method is provided for non-standard cases; use `createBucket(String, Region)` and pass in a `Region` enumeration value in standard cases.

      Every object stored in Amazon S3 is contained within a bucket. Buckets partition the namespace of objects stored in Amazon S3 at the top level. Within a bucket, any name can be used for objects. However, bucket names must be unique across all of Amazon S3.

      Bucket ownership is similar to the ownership of Internet domain names. Within Amazon S3, only a single user owns each bucket. Once a uniquely named bucket is created in Amazon S3, organize and name the objects within the bucket in any way. Ownership of the bucket is retained as long as the owner has an Amazon S3 account.

      To conform with DNS requirements, the following constraints apply:

      - Bucket names should not contain underscores
      - Bucket names should be between 3 and 63 characters long
      - Bucket names should not end with a dash
      - Bucket names cannot contain adjacent periods
      - Bucket names cannot contain dashes next to periods (e.g., "my-.bucket.com" and "my.-bucket" are invalid)
      - Bucket names cannot contain uppercase characters

      There are no limits to the number of objects that can be stored in a bucket. Performance does not vary based on the number of buckets used. Store all objects within a single bucket or organize them across several buckets.

      Buckets cannot be nested; buckets cannot be created within other buckets.

      Do not make bucket create or delete calls in the high availability code path of an application. Create or delete buckets in a separate initialization or setup routine that runs less often.

      To create a bucket, authenticate with an account that has a valid AWS Access Key ID and is registered with Amazon S3. Anonymous requests are never allowed to create buckets.

      パラメータ:
        `bucketName` - The name of the bucket to create.
        `region` - The Amazon S3 region in which to create the new bucket.
      戻り値:
        The newly created bucket.
      例外:
        `AmazonClientException` - If any errors are encountered in the client while making the request or handling the response.
        `AmazonServiceException` - If any errors occurred in Amazon S3 while processing the request.

      Gets the `AccessControlList` (ACL) for the specified object in Amazon S3.

      Each bucket and object in Amazon S3 has an ACL that defines its access control policy. When a request is made, Amazon S3 authenticates the request using its standard authentication procedure and then checks the ACL to verify the sender was granted access to the bucket or object. If the sender is approved, the request proceeds. Otherwise, Amazon S3 returns an error.

      パラメータ:
        `bucketName` - The name of the bucket containing the object whose ACL is being retrieved.
        `key` - The key of the object within the specified bucket whose ACL is being retrieved.

      Gets the object stored in Amazon S3 under the specified bucket and key.

      Be extremely careful when using this method; the returned Amazon S3 object contains a direct stream of data from the HTTP connection. The underlying HTTP connection cannot be closed until the user finishes reading the data and closes the stream. Therefore:

      - Use the data from the input stream in Amazon S3 object as soon as possible
      - Close the input stream in Amazon S3 object as soon as possible
      If these rules are not followed, the client can run out of resources by allocating too many open, but unused, HTTP connections.

      To get an object from Amazon S3, the caller must have `Permission.Read` access to the object.

      If the object fetched is publicly readable, it can also read it by pasting its URL into a browser.

      For more advanced options (such as downloading only a range of an object's content, or placing constraints on when the object should be downloaded) callers can use `getObject(GetObjectRequest)`.

      Callers should be very careful when using this method; the returned Amazon S3 object contains a direct stream of data from the HTTP connection. The underlying HTTP connection cannot be closed until the user finishes reading the data and closes the stream. Callers should therefore:

      - Use the data from the input stream in Amazon S3 object as soon as possible,
      - Close the input stream in Amazon S3 object as soon as possible.

      If callers do not follow those rules, then the client can run out of resources if allocating too many open, but unused, HTTP connections.

      To get an object from Amazon S3, the caller must have `Permission.Read` access to the object.

      If the object fetched is publicly readable, it can also read it by pasting its URL into a browser.

      When specifying constraints in the request object, the client needs to be prepared to handle this method returning `null` if the provided constraints aren't met when Amazon S3 receives the request.

      If the advanced options provided in `GetObjectRequest` aren't needed, use the simpler `getObject(String bucketName, String key)` method.

                                           AmazonServiceException

      Uploads a new object to the specified Amazon S3 bucket. The `PutObjectRequest` contains all the details of the request, including the bucket to upload to, the key the object will be uploaded under, and the file or input stream containing the data to upload.

      Amazon S3 never stores partial objects; if during this call an exception wasn't thrown, the entire object was stored.

      Depending on whether a file or input stream is being uploaded, this method has slightly different behavior.

      When uploading a file:

      - The client automatically computes a checksum of the file. Amazon S3 uses checksums to validate the data in each file.
      - Using the file extension, Amazon S3 attempts to determine the correct content type and content disposition to use for the object.

      When uploading directly from an input stream:

      - Be careful to set the correct content type in the metadata object before directly sending a stream. Unlike file uploads, content types from input streams cannot be automatically determined. If the caller doesn't explicitly set the content type, it will not be set in Amazon S3.
      - Content length must be specified before data can be uploaded to Amazon S3. Amazon S3 explicitly requires that the content length be sent in the request headers before it will accept any of the data. If the caller doesn't provide the length, the library must buffer the contents of the input stream in order to calculate it.

      If versioning is enabled for the specified bucket, this operation will never overwrite an existing object with the same key, but will keep the existing object as an older version until that version is explicitly deleted (see `deleteVersion(String, String, String)`.

      If versioning is not enabled, this operation will overwrite an existing object with the same key; Amazon S3 will store the last write request. Amazon S3 does not provide object locking. If Amazon S3 receives multiple write requests for the same object nearly simultaneously, all of the objects might be stored. However, a single object will be stored with the final write request.

      When specifying a location constraint when creating a bucket, all objects added to the bucket are stored in the bucket's region. For example, if specifying a Europe (EU) region constraint for a bucket, all of that bucket's objects are stored in the EU region.

      The specified bucket must already exist and the caller must have `Permission.Write` permission to the bucket to upload an object.

      Sets the logging configuration for the specified bucket. The bucket logging configuration object indicates whether server access logging is enabled or not for the specified bucket, the destination bucket where server access logs are delivered, and the optional log file prefix.

      In order to deliver server access logs, the destination bucket must have log delivery write permissions. You can use the `CannedAccessControlList.LogDeliveryWrite` ACL to quickly add the correct permissions to your destination bucket, or you can modify the bucket's existing ACL to grant the `GroupGrantee.LogDelivery` group grantee the `Permission.Write` permission.

      Changes to the logging status for a bucket are visible in the configuration API immediately, but they take time to actually affect the delivery of log files. For example, if logging is enabled for a bucket, some requests made in the following hour might be logged, while others might not. Or, if you change the target bucket for logging from bucket A to bucket B, some logs for the next hour might continue to be delivered to bucket A, while others might be delivered to the new target bucket B. In all cases, the new settings will eventually take effect without any further action on your part.

      Returns the versioning configuration for the specified bucket.

      A bucket's versioning configuration can be in one of three possible states:

      - `BucketVersioningConfiguration.OFF`
      - `BucketVersioningConfiguration.ENABLED`
      - `BucketVersioningConfiguration.SUSPENDED`

      By default, new buckets are in the `off` state. Once versioning is enabled for a bucket the status can never be reverted to `off`.

      The versioning configuration of a bucket has different implications for each operation performed on that bucket or for objects within that bucket. For example, when versioning is enabled a `PutObject` operation creates a unique object version-id for the object being uploaded. The The `PutObject` API guarantees that, if versioning is enabled for a bucket at the time of the request, the new object can only be permanently deleted using a `DeleteVersion` operation. It can never be overwritten. Additionally, the `PutObject` API guarantees that, if versioning is enabled for a bucket the request, no other object will be overwritten by that request. Refer to the documentation sections for each API for information on how versioning status affects the semantics of that particular API.

      Amazon S3 is eventually consistent. It can take time for the versioning status of a bucket to be propagated throughout the system.

      By default, new buckets are in the `off` state. Once versioning is enabled for a bucket the status can never be reverted to `off`.

      Objects created before versioning was enabled or when versioning is suspended will be given the default `null` version ID (see `Constants.NULL_VERSION_ID`). Note that the `null` version ID is a valid version ID and is not the same as not having a version ID.

      Returns the website configuration for the specified bucket. Bucket website configuration allows you to host your static websites entirely out of Amazon S3. To host your website in Amazon S3, create a bucket, upload your files, and configure it as a website. Once your bucket has been configured as a website, you can access all your content via the Amazon S3 website endpoint. To ensure that the existing Amazon S3 REST API will continue to behave the same, regardless of whether or not your bucket has been configured to host a website, a new HTTP endpoint has been introduced where you can access your content. The bucket content you want to make available via the website must be publicly readable.

      Returns a pre-signed URL for accessing an Amazon S3 resource.

      Pre-signed URLs allow clients to form a URL for an Amazon S3 resource, and then sign it with the current AWS security credentials. The pre-signed URL can be shared to other users, allowing access to the resource without providing an account's AWS security credentials.

      Pre-signed URLs are useful in many situations where AWS security credentials aren't available from the client that needs to make the actual request to Amazon S3.

      For example, an application may need remote users to upload files to the application owner's Amazon S3 bucket, but doesn't need to ship the AWS security credentials with the application. A pre-signed URL to PUT an object into the owner's bucket can be generated from a remote location with the owner's AWS security credentials, then the pre-signed URL can be passed to the end user's application to use.

      パラメータ:
        `bucketName` - The name of the bucket containing the desired object.

      Initiates a multipart upload and returns an InitiateMultipartUploadResult which contains an upload ID. This upload ID associates all the parts in the specific upload and is used in each of your subsequent `uploadPart(UploadPartRequest)` requests. You also include this upload ID in the final request to either complete, or abort the multipart upload request.
      パラメータ:
        `request` - The InitiateMultipartUploadRequest object that specifies all the parameters of this operation.
      戻り値:

                                             AmazonServiceException

      Uploads a part in a multipart upload. You must initiate a multipart upload before you can upload any part.

      Your UploadPart request must include an upload ID and a part number. The upload ID is the ID returned by Amazon S3 in response to your Initiate Multipart Upload request. Part number can be any number between 1 and 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being uploaded. If you upload a new part using the same part number that was specified in uploading a previous part, the previously uploaded part is overwritten.

      To ensure data is not corrupted traversing the network, specify the Content-MD5 header in the Upload Part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error.

      When you upload a part, the returned UploadPartResult contains an ETag property. You should record this ETag property value and the part number. After uploading all parts, you must send a CompleteMultipartUpload request. At that time Amazon S3 constructs a complete object by concatenating all the parts you uploaded, in ascending order based on the part numbers. The CompleteMultipartUpload request requires you to send all the part numbers and the corresponding ETag values.

      パラメータ:
        `request` - The UploadPartRequest object that specifies all the parameters of this operation.
      戻り値:
        An UploadPartResult from Amazon S3 containing the part number and ETag of the new part.

      Lists the parts that have been uploaded for a specific multipart upload.

      This method must include the upload ID, returned by the `initiateMultipartUpload(InitiateMultipartUploadRequest)` operation. This request returns a maximum of 1000 uploaded parts by default. You can restrict the number of parts returned by specifying the MaxParts property on the ListPartsRequest. If your multipart upload consists of more parts than allowed in the ListParts response, the response returns a IsTruncated field with value true, and a NextPartNumberMarker property. In subsequent ListParts request you can include the PartNumberMarker property and set its value to the NextPartNumberMarker property value from the previous response.

      パラメータ:
        `request` - The ListPartsRequest object that specifies all the parameters of this operation.
      戻り値:

                                           AmazonServiceException

      Aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads may or may not succeed. As a result, it may be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.
      パラメータ:
        `request` - The AbortMultipartUploadRequest object that specifies all the parameters of this operation.
      例外:

      Completes a multipart upload by assembling previously uploaded parts.

      You first upload all parts using the `uploadPart(UploadPartRequest)` method. After successfully uploading all individual parts of an upload, you call this operation to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the CompleteMultipartUpload request, you must provide the parts list. For each part in the list, you provide the part number and the ETag header value, returned after that part was uploaded.

      Processing of a CompleteMultipartUpload request may take several minutes to complete.

      パラメータ:
        `request` - The CompleteMultipartUploadRequest object that specifies all the parameters of this operation.
      戻り値:
        A CompleteMultipartUploadResult from S3 containing the ETag for the new object composed of the individual parts.
      例外:

      Lists in-progress multipart uploads. An in-progress multipart upload is a multipart upload that has been initiated, using the InitiateMultipartUpload request, but has not yet been completed or aborted.

      This operation returns at most 1,000 multipart uploads in the response by default. The number of multipart uploads can be further limited using the MaxUploads property on the request parameter. If there are additional multipart uploads that satisfy the list criteria, the response will contain an IsTruncated property with the value set to true. To list the additional multipart uploads use the KeyMarker and UploadIdMarker properties on the request parameters.

      パラメータ:
        `request` - The ListMultipartUploadsRequest object that specifies all the parameters of this operation.
      戻り値:
        A MultipartUploadListing from Amazon S3.
      例外:

        `AmazonServiceException` - If any errors occurred in Amazon S3 while processing the request.

    - #### getCachedResponseMetadata

          S3ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

      Gets additional metadata for a previously executed successful request. The returned metadata is typically used for debugging issues when a service isn't acting as expected. This data isn't considered part of the result data returned by an operation; as so, it's available through this separate diagnostic interface.

      Response metadata is only cached for a limited period of time. Use this method to retrieve the response metadata as soon as possible after executing a request.

      パラメータ:
        `request` - The originally executed request.
      戻り値:
        The response metadata for the specified request, or `null` if none is available.
