All Known Implementing Classes:

AbstractMultiPersistenceFactory, AbstractSinglePersistenceFactory, DynObjectPersistenceFactory, SimplePersistenceFactory

public interface PersistenceFactory

Interface for factories of objects that no implements Persistent and must be supported by PersistenceManager.

This can be used when the objects to persist can't be created by empty constructor.

Load a instance of classToUse from state data.

Parameters:

state -

object -

Throws:

PersistenceException

saveToState

void saveToState(PersistentState state,
                 Object obj)
                 throws PersistenceException

Fill state with data to persist of obj.

Parameters:

state -

obj -

Throws:

PersistenceException
