Hi, I'm using Eclise 3.0.2 with AspectJ 1.5.0M1
The problem is I can't catch the pointcut on the method i "introduced" in
another aspect.
i have the following model:
interface ISomeInterface{
public void setProperty(String newValue);
}
aspect ASomeInterfaceImpl{
private String ISomeInterface._property;
public void ISomeInterface.setProperty(String newValue){
_property = newValue;
}
}
aspect AEventListener{
pointcut propertyChanged() :
execution(ISomeInterface+.setProperty(..));
after() : propertyChanged() {
// event handling code
// never reached
// so i tried to change the pointcut to:
pointcut propertyChanged() :
set(String ISomeInterface._property);
// but it doesn't work either :(((
}
}
so, from i can see the AEventListener is weaved(???) before the
ASomeIntImpl(which defines the setProperty default behaviour).

yeah, u r right, it works in isolation, so it must be some my internal bug

Does that pointcut compile?

You need a return value for the setProperty() method()
pointcut propertyChanged():
execution(* ISomeInterface+.setProperty(..));
You can't get into ordering problems since the changes to the type
system (your method ITD) happen before the advice matching.
This works for me:
interface I { public void m(String s); }
aspect X { public void I.m(String s) {} }
aspect Y { after(): execution(* I+.m(..)) {} }
C:\>ajc X.aj Y.aj I.java -showWeaveInfo
Type 'X' (X.aj:1) advised by after advice from 'Y' (Y.aj:1)
Type 'I' (I.java) has intertyped method from 'X' (X.aj:'void
I.m(java.lang.String)')
The first line of weaving info indicates the pointcut matched.
I must admit I am on 1.5.0M2 but I don't think anything in that area for
ages.
cheers,
Andy.
