| <DT>public interface <B>PersistenceCapable</B></DL> |
| |
| <P> |
| A class that can be managed by a JDO implementation must implement this interface. |
| |
| <P>Every class whose instances can be managed by a JDO PersistenceManager must |
| implement the PersistenceCapable interface. |
| |
| <P>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, or deleted; and to get its associated |
| PersistenceManager if it has one. |
| |
| <P>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. |
| |
| <P>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. |
| |
| <P>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'. |

| String name, and Float salary) would have the method generated: |
