Instance Attribute Details

#bucket ⇒ String

**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][2

in the *Amazon S3 User Guide*.

<note markdown=“1”> Access points and Object Lambda access points are not supported by directory buckets.

</note>

**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. For more information about S3 on Outposts ARNs, see

What is S3 on Outposts?][3

in the *Amazon S3 User Guide*.

  include Aws::Structure
end

#continuation_token ⇒ String

‘ContinuationToken` indicates to Amazon S3 that the list is being continued on this bucket with a token. `ContinuationToken` is obfuscated and is not a real key. You can use this `ContinuationToken` for pagination of the list results.

Returns:

• (String)

# File 'lib/aws-sdk-s3/types.rb', line 10954

  SENSITIVE = []
  include Aws::Structure
end

#delimiter ⇒ String

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

<note markdown=“1”> * **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*.

  :start_after,

  :expected_bucket_owner,
  :optional_object_attributes)
  SENSITIVE = []
  include Aws::Structure
end

#encoding_type ⇒ String

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].

<note markdown=“1”> 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`.

  SENSITIVE = []
  include Aws::Structure
end

#expected_bucket_owner ⇒ String

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).

Returns:

• (String)

  SENSITIVE = []
  include Aws::Structure
end

#fetch_owner ⇒ Boolean

The owner field is not present in ‘ListObjectsV2` by default. If you want to return the owner field with each key in the result, then set the `FetchOwner` field to `true`.

<note markdown=“1”> **Directory buckets** - For directory buckets, the bucket owner is returned as the object owner for all objects.
