Accessing Target Object From Proxy

[cameronjones]

hi ng,

could someone give me some hints on how to configure a proxy so that i can access the target object? eg:


Cast cast = (Cast) proxy;
Target = (Target) cast.getTargetObject();


thanks,
cam

ok, but how can i access this from the proxy?

here was what i was thinking. I was going to add an introduction advice to the proxy:


public interface IProxy {

public Object getProxiedObject();

}


but how can i gain access to the proxied object from the mixin?


public class ProxyInterceptor extends DelegatingIntroductionInterceptor implements IProxy {

public ProxyInterceptor() {
super();
}

public Object getProxiedObject() {
// how can i return the proxied object here?
}

}



public class ProxyAdvisor extends DefaultIntroductionAdvisor {

public ProxyAdvisor() {
super(new ProxyInterceptor(), IProxy.class);
}

}


thanks,
cam

If you want to get the target from the proxy, you do:
Advised advised = (Advised) proxy;
Target target = proxy.getTargetSource().getTarget();


If you want to get the proxy from the target or advice, you set exposeProxy to true in the ProxyFactoryBean, and from your target or advice, you call AopContext.currentProxy();
