| RE: [aspectj-dev] Advice Precedence Question |
Ron, I had a similar problem long ago as a switch between versions caused my advice to change ordering. If I remember the discussion back then the "algorithm" for advice ordering was determined by alphabetic ordering.

However, I'm wondering if in practice there's any way that advice at a join point across the aspects could run in different precedence order. Specifically if both A and B have before and after returning advice that match the same join point, will AspectJ ever produce results that run like this? before from A before from B join point executes after returning from A after returning from B This is a problem for us because we have a large number of aspects that might run independently at a given join point and we don't care about ordering except we do maintain a thread local stack so we do want consistent dressing/undressing. Given the number of independent monitor aspects (already about 20 and growing and user extensible even with XML definition), I don't see a reasonable way to force a total ordering with declare precedence. Indeed, I'd argue that consistent precedence ordering is desirable even if which aspect will be higher precedence isn't defined. _______________________________________________ aspectj-dev mailing list aspectj-dev@xxxxxxxxxxx https://dev.eclipse.org/mailman/listinfo/aspectj-dev
