Examples of com.amazonaws.services.s3.model.ObjectMetadata

com.amazonaws.services.s3.model.ObjectMetadata
Represents the object metadata that is stored with Amazon S3. This includes custom user-supplied metadata, as well as the standard HTTP headers that Amazon S3 sends and receives (Content-Length, ETag, Content-MD5, etc.).
