Hi Andy,
I am having an issue in understanding why one of the method call is intercepted
and why the other is not. In the first case, for pointcut definition, all
method calls to hasNext is intercepted which also intercepts "hasNext" method
whose object is of type "org.apache.fop.fo.FONode$FONodeIterator"
The hierarchy is:-
public interface FONodeIterator extends ListIterator{}
Now the aspect code is as follows:-
pointcut HasNext_hasnext(Iterator i) : (call(* Iterator.hasNext()) &&
target(i));
after (Iterator i) : HasNext_hasnext(i) {//advice code}
Similarly, consider following as the second case, pointcut intercepting "put"
method, but it does not intercept "put" method whose object is of type
ConcurrentMap
Code is :-
pointcut UnsafeMapIterator_updateMap(Map map) : (call(* Map.put*(..)) &&
target(map));
after (Map map) : UnsafeMapIterator_updateMap(map) {
//advice code
}
If I use subtype pattern e.g. call(* Map+.put*(..), then ConcurrentMap.put
method-call will also be intercepted. This just confuses me even more, because
if subtype pattern is used to intercept all methods in class or subtype of
it,then I don't understand why in the first case
"org.apache.fop.fo.FONode$FONodeIterator.hasNext" is intercepted. I have also
used -showWeaveInfo to confirm the behaviour.
Regards,
Omar
