Subject: Re: [aspectj-users] Limiting depth of pointcut for subclasses
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Although I fail to comprehend why you would ever need this (maybe you
should consider modifying your design), my guess would be that you can
only achieve such an effect by using the if() pointcut and applying
reflection to determine the classes' location in the hierarchy (e.g., by
using the Class.getInterfaces method). Your pointcut then would probably
look something like pointcut pc(A obj):
this(obj) &&
if(Arrays.asList(obj.getClass().getInterfaces()).contains(A.class)))
