        public void registerImplementation​(java.lang.Class facadeType,
                                   java.lang.Class storeType,

        Register a facade implementation.
        Parameters:

        public java.lang.Class getImplementation​(java.lang.Class facadeType,
                                         java.lang.Class storeType)
        Return the implementation for the given facade and store.
        Parameters:
        facadeType - the facade interface

      • getImplementation

        public java.lang.Class getImplementation​(java.lang.Class facadeType,
                                         java.lang.Class storeType,
                                         java.lang.Class defaultType)
        Return the implementation for the given facade and store. If no registered implementation is found then returns the given default type provided it the facade type is assignable from the deafult type.
        Parameters:
        facadeType - the facade interface
        storeType - the store's StoreManager type, or null for generic
        implType - the registered implementor
        defaultType - class if no registered implementation is available.
