Class GrapheneProxyHandler

java.lang.Object

org.jboss.arquillian.graphene.proxy.GrapheneProxyHandler

All Implemented Interfaces:

InvocationHandler, net.sf.cglib.proxy.Callback, net.sf.cglib.proxy.MethodInterceptor

public class GrapheneProxyHandler
extends Object
implements net.sf.cglib.proxy.MethodInterceptor, InvocationHandler

Invocation handler which wraps the given target for invocation (as the target instance for future computation of target).

This handlers determines whenever the result of invocation can be proxied and if yes, it recursively wraps it with proxy using this invocation handler.

Method Detail

forTarget

public static GrapheneProxyHandler forTarget(Object target)

Returns invocation handler which wraps the given target instance.

Parameters:

target - the target of invocation

Returns:

invocation handler which wraps the given target instance

forFuture

public static GrapheneProxyHandler forFuture(GrapheneProxy.FutureTarget future)

Returns invocation handler which wraps the target for future computation.

Parameters:

future - the future target

Returns:

invocation handler which wraps the target for future computation

invoke

public Object invoke(Object proxy,
            Method method,
            Object[] args)
              throws Throwable

End point for handling invocations on proxy.

Decides whenever the result of invocation is proxyable and if yes, it returns the proxy using new instance of GrapheneProxyHandler wrapping the result of invocation.

The method specifically handles GrapheneProxyInstance.unwrap() method which returns the real target for invocation.

Specified by:

invoke in interface InvocationHandler

Throws:

Throwable

intercept

public Object intercept(Object obj,
               Method method,
               Object[] args,
               net.sf.cglib.proxy.MethodProxy proxy)
                 throws Throwable

Delegates to invoke(Object, Method, Object[]) to serve as MethodInterceptor.

Specified by:

intercept in interface net.sf.cglib.proxy.MethodInterceptor

Throws:

Throwable

resetInterceptors

public void resetInterceptors()

Resets the interceptors
