  • Method Details

    • bucket

      public final String bucket()

      Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

      Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.

      Access points and Object Lambda access points are not supported by directory buckets.

      S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name.

    • delimiter

      public final String delimiter()

      A delimiter is a character that you use to group keys.

      • Directory buckets - For directory buckets, / is the only supported delimiter.

      • Directory buckets - When you query ListObjectsV2 with a delimiter during in-progress multipart uploads, the CommonPrefixes response parameter contains the prefixes that are associated with the in-progress multipart uploads. For more information about multipart uploads, see Multipart Upload Overview in the Amazon S3 User Guide.

    • encodingType

      public final EncodingType encodingType()

      Encoding type used by Amazon S3 to encode the object keys in the response. Responses are encoded only in UTF-8. An object key can contain any Unicode character. However, the XML 1.0 parser can't parse certain characters, such as characters with an ASCII value from 0 to 10. For characters that aren't supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response. For more information about characters to avoid in object key names, see Object key naming guidelines.

      When using the URL encoding type, non-ASCII characters that are used in an object's key name will be percent-encoded according to UTF-8 code values. For example, the object test_file(3).png will appear as test_file%283%29.png.

      If the service returns an enum value that is not available in the current SDK version, encodingType will return EncodingType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from encodingTypeAsString().

      Returns:

      Returns:
      The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

    • optionalObjectAttributes

      public final List<OptionalObjectAttributes> optionalObjectAttributes()

      Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.

      This functionality is not supported for directory buckets.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasOptionalObjectAttributes() method.

      Returns:
      Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.

      This functionality is not supported for directory buckets.

    • hasOptionalObjectAttributes

      public final boolean hasOptionalObjectAttributes()
      For responses, this returns true if the service returned a value for the OptionalObjectAttributes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • optionalObjectAttributesAsStrings

      public final List<String> optionalObjectAttributesAsStrings()

      Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.
