Re: [aspectj-users] How to get an initialized instance reference from co

[Tahir Akhtar <tahir@xxxxxxxxxxxxxxxxxxx>]

The second issue (no matched join points) is due to the fact that ArrayList is a JDK class and "execution" of its constructor cannot be weaved.
So, I guess, you will have to stick with the "call" point cuts when dealing with the JDK classes.

I am not sure, but I guess an "around advice" to constructor "call" might do the trick for you.

Hi, everyone.

I'm using aspectJ to help me get an initialized instance reference after its constructor called. 

At first, I wrote some code like this:

after() returning (ArrayList l): call(ArrayList.new(..))

but the reference l I got seems not be initialized yet.

This is the first rule mentioned in http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg00019.html

Then I changed my code into this:

after(ArrayList l) returning: this(l) &&execution(ArrayList.new(..))

(which is written according to the second rule mentioned in msg00019)

but this time, no matched join point has been found in the program...

My question is : how can I get an initialized instance reference using AspectJ?

Thanks very much!
