List of jdoReplaceStateManager() Examples

Examples of jdoReplaceStateManager()

javax.jdo.spi.PersistenceCapable.jdoReplaceStateManager()
This method sets the StateManager instance that manages the state of this instance. This method is normally used by the StateManager during the process of making an instance persistent, transient, or transactional. The caller of this method must have JDOPermission for the instance, if the instance is not already owned by a StateManager. If the parameter is null, and the StateManager approves the change, then the jdoFlags field will be reset to READ_WRITE_OK. If the parameter is not null, and the security manager approves the change, then the jdoFlags field will be reset to LOAD_REQUIRED. @param sm The StateManager which will own this instance, or nullto reset the instance to transient state @throws SecurityException if the caller does not have JDOPermission @see JDOPermission
