java.io.Serializable

public class Snapshot<T>
extends java.lang.Object

• The Value Domain: describes the set of resources that the snapshot represents.
• The Type of Values: Which values associated with a resource should be part of the snapshot view. The following types of values can be obtained as a snapshot:
  • Snapshot of Ref : Contains the set of Ref objects representing the resources that existed at a given time
  • Snapshot of Digest : Contains the set of Digest objects for resources that existed at a given time
  • Snapshot of CanonicalResource : Contains canonical (in-memory, non-serialized) values of resources that existed at a given time
  • Snapshot of PortableResource : Contains portable (serialized) values of resources that existed at a given time.
