All Implemented Interfaces:

CreationListener, InternalFactory<T>

final class FactoryProxy<T>
extends Object
implements InternalFactory<T>, CreationListener

A placeholder which enables us to swap in the real factory once the injector is created. Used for a linked binding, so that getting the linked binding returns the link's factory.
