Class JavaProxyClass

java.lang.Object

org.jruby.RubyBasicObject

org.jruby.RubyObject

org.jruby.javasupport.proxy.JavaProxyReflectionObject

org.jruby.javasupport.proxy.JavaProxyClass

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<IRubyObject>, InstanceVariables, InternalVariables, IRubyObject, CoreObjectType

public class JavaProxyClass
extends JavaProxyReflectionObject

Generalized proxy for classes and interfaces. API looks a lot like java.lang.reflect.Proxy, except that you can specify a super class in addition to a set of interfaces. The main implication for users of this class is to handle the case where a proxy method overrides an existing method, because in this case the invocation handler should "default" to calling the super implementation {JavaProxyMethod.invokeSuper}.
