com.sinacloud.scs.services.scs.model.GetObjectMetadataRequest

public class GetObjectMetadataRequest
extends SCSWebServiceRequest

Provides options for obtaining the metadata for the specified Amazon S3 object without actually fetching the object contents. This is useful if obtaining only object metadata, and avoids wasting bandwidth from retrieving the object data.

The object metadata contains information such as content type, content disposition, etc., as well as custom user metadata that can be associated with an object in Amazon S3.

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