Examples of org.apache.openjpa.kernel.PCState

org.apache.openjpa.kernel.PCState
Base class for all lifecycle states. Each instance is managed by a {@link 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. @author Abe White
