Re: [aspectj-dev] Set-Pointcut does not match
|
Ok, I can't work it out, so I suggest you sneak up on the problem
sideways. Write a method that simply sets the state to two and then see
if that triggers your advice. Perhaps there's a problem with your
pointcut.
Not much help, but that's how I'd approach it.
Cheers,
Nick

Hi.
Could probably anybody explain to me, while the last advice here
never matches?
package rv;
aspect PushUntilPop pertarget(pushPop()){
int state = 0;
public PushUntilPop() {
System.out.println("new instance "+this);
}
pointcut pushPop() : pu(Object) || po();
pointcut pu(Object o): call(* IStack.push(..)) && args(o);
pointcut po(): call(* IStack.pop());
pointcut match(): set(* PushUntilPop.state);
after() returning (Object o): po() {
if(state==0) {
System.out.println("0->2"+this);
state=2;
}
}
after(Object o) returning: pu(o) {
if(state==0) {
System.out.println("0->1"+this);
state=1;
}
}
after() returning (Object o): po() {
if(state==1) {
System.out.println("1->2"+this);
state=2;
}
}
after(Object o) returning: pu(o) {
if(state==1) {
System.out.println("1->1"+this);
state=1;
}
}
before(): set(* state) {
if(state==2)
System.out.println("Matched."+this);
}
after(): execution(public static void main(String[])) {
System.out.println(state);
}
void foo() {
System.out.println();
}
}
I am never seeing the output "Matched." - though the other advices
function and the state is set to 2 at some point. The whole advice is
never executed. But as you can easily see any of the others *does*
set the field "state".
Strange...
