Examples of org.apache.openjpa.kernel.StateManagerImpl

org.apache.openjpa.kernel.StateManagerImpl
Implementation of the {@link OpenJPAStateManager} interface for usewith this runtime. Each state manager manages the state of a single persistence capable instance. The state manager is also responsible for all communications about the instance to the {@link StoreManager}. The state manager uses the State pattern in both its interaction with the governed instance and its interaction with the broker. In its interactions with the persistence capable instance, it uses the {@link FieldManager} interface. Similarly, when interacting with thebroker, it uses the {@link PCState} singleton that representsthe current lifecycle state of the instance. @author Abe White
