Re: [aspectj-users] Target type wildcard and variable binding

[Adrian Colyer <adrian.colyer@xxxxxxxxx>]

The setName method is declared in JComponent - the declaring type
pattern of the call pcd matches based on where a method is declared,
whereas the target pcd matches based on  the runtime type of the
target object.

Since JList is_a Component, you can simplify the advice in this case to:

 before(JList list) : (call (* set*(..))) && target(list) {
         AnalysisHelper.check(list);
 }

assuming from your declaration that your intent is to match all setXXX
methods called on instances of JList?
