Examples of OpenJPAStateManager

org.apache.openjpa.kernel.OpenJPAStateManager
Interface implemented by OpenJPA state managers. 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 fetchXXXField and storeXXXField methods can be used to get and set fields of the managed persistent object. Most back-end code, however, should use the similar fetchXXX and storeXXX methods in place of the field methods. These methods function just like the field methods, but also pass the value through the externalizer and factory the field may have. @author Abe White
