Interface StateManageableMessageContext

All Superinterfaces:

MessageContext

All Known Implementing Classes:

DefaultMessageContext

public interface StateManageableMessageContext
extends MessageContext

A message context whose internal state can be managed by an external care-taker. State management employs the GOF Memento pattern. This context can produce a serializable memento representing its internal state at any time. A care-taker can then use that memento at a later time to restore any context instance to a previous state.
