| It goes with the aspect declaration:
public aspect Foo pertypewithin(...mypackage.*) { // All the types in "mypackage". ...
}
Here's the manual page for it, which is not as easy to get to with a google search as you would think (aspectj list traffic comes up first...)
Here's a very long message on the aspectj-dev list that shows an example:
Also, I couldn't remember if pertypewithin actually works with JDK 1.4, but apparently it does: http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg03995.html
Can you give us some more details about what you're trying to do?
Hope this helps! dean

I'm quite new to AspectJ so please apologize that some terms might not
fully hit the target.
I tried hard to find the 'pertypewithin' keyword which allows me to do
exactly what I wanted. (Guess what - debug logging and tracing). I'm
working with a 1.4 JDK. Inspecting the generated code there is one thing
that makes me unhappy because it is not as good as it could be:
To access the DeclaringType's aspect instance in the advice I need to call aspectOf(thisJoinPointStaticPart.getSignature().getDeclaringType()).
This generates code that calls the static aspectOf(Class) method of the
aspect to look up the DeclaringType's aspect instance via
reflection. This simply returns a pointer back to the member that is already statically accessible in the DeclaringType
(ajc$<...>$ptwAspectInstance).
This could be directly accessible even in the static arrear (if(...)) allowing some major improvements - but unfortunately it not exposed to the advice.
Am I just missing an other key word to get direct access? Or is this a
feature that needs to be coded?
If needed I can give more details.
Thanks for any feedback,
Andreas.
