Examples of org.jpox.identity.OID

org.jpox.identity.OID
Interface for a datastore-identity class to implement. Please refer to the JDO2 specification 5.4.3 for precise requirements of such a class. These include
- Has to implement Serializable
- Serializable fields have to be public
- Has to have a constructor taking a String (the same String that toString() returns)
