                                                                            Class<T> facadeInterface)

                                                                            IllegalAccessException

Create facade proxy from ServiceFacade. Java does not allow typed argument with both typed and static bounds, i.e. does not compile. To work around this limitation and to ensure that facaded services implement both the facade interface and SharedStoreSetter, I'm using . This makes the facade interface - T - require to implement SharedStoreSetter. It does not logically belong to the facade interface, but I guess I can live with that.

Parameters:

svcFacade - initialized with services implementing the facadeInterface

facadeInterface - has to implement SharedStoreSetter

Returns:

facaded service proxy

Throws:

InstantiationException

IllegalAccessException
