Re: [aspectj-users] precedence inside a single aspect

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

Advice ordering rules are discussed here (end of the page):
http://www.eclipse.org/aspectj/doc/released/progguide/semantics-advice.html
(declare precedence can't be used for ordering advice within an aspect)

This ordering will compile:
aspect Precedence {
    pointcut p1() : execution(String Preced.foo());
    pointcut p2() : execution(String Preced.foo());

    String around () : p1(){
        System.err.println("around in");
        proceed();
        System.err.println("around out");
        return "around";
    }

    before () : p1(){
        System.err.println("before");
    }
    after () : p2(){
        System.err.println("after");
    }
    //declare precedence: Precedence.p1, Precedence.p2;
}


cheers
Andy
