| <P>This package contains the interfaces and classes used by JDO implementations. |
| <P>JDO defines interfaces and classes to be used by application programmers |
| when using classes whose instances are to be stored in persistent storage |
| (persistence-capable classes), and specifies the contracts between |
| suppliers of persistence-capable classes and the |
| runtime environment (which is part of the JDO implementation). |
| <P>The PersistenceCapable interface is implemented by all classes |
| whose instances are to be made persistent. The implementation might be |
| done by a combination of techniques, as determined by the JDO vendor: |
| <ul> |
| <li>Pre-processing .java files |
| <li>Post-processing .class files |
| <li>Generating .java or .class files directly from an abstraction |
| </ul |
| <P>The StateManager interface is the implementation's contact point with |
| the PersistenceCapable instances. It defines methods that are called by |
| the PersistenceCapable instances to implement the required PersistenceCapable |
| behavior for persistent and transactional instances. |
| <P>The JDOPermission class is used to manage security controls on JDO implementations. |
| <P>The RegisterClassEvent class and RegisterClassListener interface are used |
| by JDO implementations that need access to metadata of PersistenceCapable classes. |
| <P>The JDOImplHelper class contains helper methods for JDO implementations. |
