Method Detail

registerImplementation

public void registerImplementation(Class facadeType,
                                   Class storeType,
                                   Class implType)

Register a facade implementation.

Parameters:

facadeType - the facade interface

storeType - the store's StoreManager type, or null for generic

implType - the class implementing the facade

getImplementation

public Class getImplementation(Class facadeType,
                               Class storeType)

Return the implementation for the given facade and store.

Parameters:

facadeType - the facade interface

storeType - the store's StoreManager type, or null for generic

implType - the registered implementor

getImplementation

public Class getImplementation(Class facadeType,
                               Class storeType,
                               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.
