doLoad

protected PersistentAgreementFactory[] doLoad()
                                       throws PersistedResourceException

Description copied from class: AbstractWSAG4JPersistence

Loads the agreement factories for this persistence layer. The load method is invoked during the initialization process of the persistence layer (see #initialize()) or during a AbstractWSAG4JPersistence.find(String), AbstractWSAG4JPersistence.list() or AbstractWSAG4JPersistence.remove(String) operation

Specified by:

doLoad in class AbstractWSAG4JPersistence

Returns:

the loaded factories

Throws:

PersistedResourceException - indicates an error while loading the persistent factories

saveAgreementFactories

public void saveAgreementFactories(PersistentAgreementFactory[] factories)

Parameters:

factories - List of factories, which should be saved/persisted.

doRemove

protected boolean doRemove(PersistentAgreementFactory factory)
                    throws PersistedResourceException

Removes a persistent factory from the persistence layer.

Specified by:

doRemove in class AbstractWSAG4JPersistence

Parameters:

factory - the factory to remove

Returns:

true if the factory was removed, otherwise false

Throws:

PersistedResourceException - indicates an error while removing the factory
