Class JDOState

java.lang.Object
  |
  +--kodo.runtime.JDOState

All Implemented Interfaces:

Serializable

public class JDOState

extends Object

implements Serializable

Base class for all JDO lifecycle states. Each JDO instance is managed by a StateManagerImpl, which in turn keeps a reference to its current state.

The state governs the behavior of the instance during all JDO 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 JDO state.
