Re: [aspectj-users] Pointcut to a Collection.add() method on a particular type of argument?
|
Thanks. What if want to advise based on an annotation rather than a type? I tried
pointcut addEntity(@MyAnnotation * s):
call( * java.util.Collection+.add( * ))
&& args(s);
But got syntax error that @MyAnnotation is not allowed.
Thx
Eric

Hi Eric,
add() signature is:
add(E e)
Thus, * matches anything, but java.lang.String is not E.
Change your pointcut to:
pointcut addEntity(String s):
call( * java.util.Collection+.add( * ))
&& args(s);
Best regards.
