Method Detail

accept

public int accept(java.lang.reflect.Method method)

Implementation of CallbackFilter.accept() to return the index of the callback we need.

The callbacks for each proxy are built up of a set of fixed callbacks for general use and then a set of callbacks that are specific to a method for use on static targets with a fixed advice chain.

The callback used is determined thus:

For exposed proxies

Exposing the proxy requires code to execute before and after the method/chain invocation. This means we must use DynamicAdvisedInterceptor, since all other interceptors can avoid the need for a try/catch block

For Object.finalize():

No override for this method is used.

For equals():

The EqualsInterceptor is used to redirect equals() calls to a special handler to this proxy.

For methods on the Advised class:

the AdvisedDispatcher is used to dispatch the call directly to the target

For advised methods:

If the target is static and the advice chain is frozen then a FixedChainStaticTargetInterceptor specific to the method is used to invoke the advice chain. Otherwise a DyanmicAdvisedInterceptor is used.

For non-advised methods:

Where it can be determined that the method will not return this or when ProxyFactory.getExposeProxy() returns false, then a Dispatcher is used. For static targets, the StaticDispatcher is used; and for dynamic targets, a DynamicUnadvisedInterceptor is used. If it possible for the method to return this then a StaticUnadvisedInterceptor is used for static targets - the DynamicUnadvisedInterceptor already considers this.
