Class PCState

java.lang.Object
  extended by org.apache.openjpa.kernel.PCState
All Implemented Interfaces:
Serializable
Direct Known Subclasses:
PNonTransDeletedState

public class PCState
extends Object
implements Serializable

Base class for all lifecycle states. Each instance is managed by a OpenJPAStateManager, which in turn keeps a reference to its current state. The state governs the behavior of the instance during all lifecycle events. The class itself is stateless, and is provided its context on each method call. This base class provides no-op implementations of all methods and maintains static singelton shared references to each possible state.
