Class TypeAdapter

  • All Implemented Interfaces:
    java.lang.reflect.InvocationHandler
    public class TypeAdapter
extends java.lang.Object
implements java.lang.reflect.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).
