RE: [aspectj-users] FW: Multiple 'functional' inheritance

["Tom Lambrechts" <tom_lambrechts@xxxxxxxxxx>]

It's seems to be more a bug in the ajdt eclipse plugin. Sometimes he adds
weaving without deleting the old. A clean project solves the problem.
I guess you are right. It was only a desperate attempt to make aspectJ more
readable for a 'non aspect minded person'. Probably a bad Idea.
Thx

You can't use declare parents to break the rules of Java.  In java one
class can extend one other class, it can't extend multiple classes. 
Do you really get a verify error if you attempt to put make multiple
classes the parent of some target type?  If you do, that's a bug and
we should be reporting earlier that it's not allowed.  What you *can*
do is have a class implement multiple interfaces and with method ITDs
on those interfaces, the target type will pick up the ITD
implementations.
