Re: [aspectj-users] Searching archive; JDK 1.4 us; features from Aspectw

[Andrew Clement <CLEMAS@xxxxxxxxxx>]

Hi,

You can find the links to archive browsing/searching
on either the 
'user resources' or the 'developer
resources' pages accessible from 
the http://eclipse.org/aspectj site.

Here's the quick link to searching
aspectj-users:

http://www.eclipse.org/search/search.cgi?ul=%2Fmhonarc%2Flists%2Faspectj-users

And the quick link for searching aspectj-dev:

http://www.eclipse.org/search/search.cgi?ul=%2Fmhonarc%2Flists%2Faspectj-dev

The features of AspectJ5 that aren't
usable with JDK1.4 are the ones 
you would expect - annotation matching/binding,
declare annotation, anything
that utilises the new Java5 language
features.  However, something like the 
new pertypewithin() instantiation model
works fine in Java 1.4.

The best resource for whats planned
for AspectJ 5 is the developers notebook
accessible from the aspectj homepage.
 That does detail which of the
Aspectwerkz features are going to be
in AspectJ5 initially - @AJ syntax 
and loadtime weaving enhancements.

For a while now AspectJ has supported
binary weaving (where you can
instrument third-party libraries that
you only have the binaries for) -
the binary weaving being either done
in batch before using the binary (via
an ANT script or in AJDT), or as the
contents of the binary are 
loaded (so called 'load time weaving').
The Aspectwerkz enhancements are going
to make this latter strategy
even *more* flexible.

Andy.

Subject	[aspectj-users] Searching archive; JDK 1.4 us;        features from Aspectwerkz

Several questions:

Is there a way to search the archive of this group/list?  I didn't
see
an obvious way to do that.

Are there some features of AspectJ 5 that are not practical to use with
JDK 1.4.x?

Is there a page somewhere that describes what features of Aspectwerkz
are available in AspectJ 5?  For instance, I got the impression from
a
shallow look at Aspectwerkz that it can instrument third-party libraries
at runtime, to trace entry/exit and function parameters.  Is that
correct?  Can this be done with AspectJ 5?
