Package net.officefloor.compile.impl.adapt

Class TypeAdapter

java.lang.Object

net.officefloor.compile.impl.adapt.TypeAdapter

All Implemented Interfaces:

InvocationHandler

public class TypeAdapter
extends Object
implements InvocationHandler

InvocationHandler to enable type compatibility between interface loaded in one ClassLoader and implementation in another. This is overcomes the assignable issues while still allowing invocation (via reflection internally).
