Examples of javax.jdo.spi.PersistenceCapable

javax.jdo.spi.PersistenceCapable
A class that can be managed by a binary-compatible JDO implementation must implement this interface.
This interface defines methods that allow the implementation to manage the instances. It also defines methods that allow a JDO aware application to examine the runtime state of instances. For example, an application can discover whether the instance is persistent, transactional, dirty, new, deleted, or detached; and to get its associated PersistenceManager, object identity, and version if it has one.
In the Reference Implementation, the JDO Enhancer modifies the class to implement PersistenceCapable prior to loading the class into the runtime environment. The Reference Enhancer also adds code to implement the methods defined by PersistenceCapable.
The extra methods in the PersistenceCapable interface might be generated by pre-processing a .java file, or might be generated from a tool directly. The exact technique for generating the extra methods is not specified by JDO.
The PersistenceCapable interface is designed to avoid name conflicts in the scope of user-defined classes. All of its declared method names are prefixed with 'jdo'. @version 2.0
