java.lang.Object

org.jboss.arquillian.graphene.proxy.GrapheneProxyHandler

org.jboss.arquillian.graphene.proxy.GrapheneContextualHandler

All Implemented Interfaces:

InvocationHandler, MethodInterceptor

public class GrapheneContextualHandler
extends GrapheneProxyHandler

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 Details

forTarget

public static GrapheneContextualHandler forTarget(GrapheneContext context,
 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

intercept

@RuntimeType
public static Object intercept(@This
 Object self,
 @FieldValue("__interceptor")
 MethodInterceptor interceptor,
 @Origin
 Method method,
 @AllArguments
 Object[] args)
                        throws Throwable

Throws:

Throwable

forFuture

public static GrapheneContextualHandler forFuture(GrapheneContext context,
 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 GrapheneContextualHandler 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

Specified by:

invoke in class GrapheneProxyHandler

Throws:

Throwable

resetInterceptors

public void resetInterceptors()

Resets the interceptors
