using AspectJ in plugin development ? [message #3331] Wed, 11 September 2002 11:58 Go to next message

Hi!

Is there anybody using aspectj for eclipse plugin development?

How complicate it would be to write an aspect which intercepts,
say call to an interface X in JDT plugin?

Would it be possible to have one aspect intercepting calls
to classes residing in several plugins?

As far as I know nobody is using aspectj for plugin development. But I think
it is easy to write aspects working like you want. All you have to do is
define the point cuts in a correct way. Something like this may work (I
havn't tested it):

pointcut calltoX(): call(* X.*(..)); // Execution of any method (not
constructors) of X

To catch all the method calls in subpackages of org.eclipse
pointcut calltoPlugin(): call(* org.eclipse..*(..));
Perhaps if all your plugins ends with Plugin under the package com.myplugs:
pointcut calltoPlugin(): call(* com.myplugs..*Plugin.*(..));
You can mix:
pointcut calltoPlugin(): call(* com.myplugs..*Plugin.*(..)) || call(*
org.eclipse..*(..));

So as you can see the only difficulty is knowing the patterns for naming the
plugin, but you can always compose differents rules if the name of the
plugins are not homogeneous.

Of course, you must have access to the source code of the plugins and
recompile them with the aspect.
