All Implemented Interfaces:

RepositoryFactory

public class CompositeRepositoryFactory
extends Object
implements RepositoryFactory

A repository factory that delegates the creation of repositories to other factories. Users can register delegate factories with addFactory(RepositoryFactory) method. Then getRepository(Class) will try on every registered factory until it finds one that creates the resulting repository. The factories will be called in the same order in which they were registered.
