Re: [aspectj-users] Capturing calls to annotated collections

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi Maik,

Unfortunately you can't currently say that in AspectJ.  The best you
could do is determine it yourself: advise the collection operations,
and then in the advice check if the target of the call has the
annotation.  Maybe use a cache of objects you know are/arent annotated
to avoid ongoing reflection (getAnnotation) costs.

cheers
Andy
