Re: [aspectj-users] Slow if()

["Andy Clement" <andrew.clement@xxxxxxxxx>]

I'm afraid that isn't possible right now.  We do support an optimized
implementation of if() pcds that only builds thisJoinPoint if the if()
condition succeeds but if() can only use static information. (I'm
talking code style here rather than annotation style).  I have thought
about improving that if() optimization for certain other situations
but haven't had the time to look into it yet - you could raise an
enhancement request where we could discuss it further in that.
Possibly I had been thinking about exposing the aspect instance for
use in the if(), maybe that plus a perthis() instantiation model would
help your situation.
