Re: [aspectwerkz-user] After throwing advice

Raka

See src/test/test/afterxxx folder in the source
AfterThrowing fully support binding of the exception type.

f.e. with 1.4 doclet syntax:

    /**
     * @AfterThrowing(type="e", pointcut="execution(*
test.afterxxx.TestBinding.throwChecked(..))")
     */
    public void logAfterBindingExact(ClassNotFoundException e) {
        TestBinding.log("afterThrowingExact " + e.getClass().getName());
    }

Also  to bind the this or target instance, use a this(..) or
target(..) pointcut designator and refer to it in the advice signature

@Before("execution(* foo.Bar.do*(..)) && this(abarinstance)")
void beforeAdvice(Bar abarinstance) { ..... }
