Hello guys
I'd like to ask whether using the if() construct in a pointcut for an
around advice, give me a better performance or not?
I decompiled a woven class and saw:
public void test() throws Exception
{
JoinPoint joinpoint = Factory.makeJP(ajc$tjp_0, this, this);
if(TestAspect.ajc$if$806(ajc$tjp_0))
{
test_aroundBody1$advice(this, joinpoint,
ajc$test_TestAspect$localAspectOf(), null, ajc$tjp_0, joinpoint);
return;
} else
{
test_aroundBody0(this, joinpoint);
return;
}
}
If I understand it correctly
JoinPoint joinpoint = Factory.makeJP(ajc$tjp_0, this, this);
has biggest impact on a performance (except method body), but it is before
if(TestAspect.ajc$if$806(ajc$tjp_0))
which is actually the test I wrote to the if() construct in TestAspect:
Object around() throws Exception : testMethods() && if (...) {
..
}
I would expect that the test will appear before Factory.makeJP and thus
we gain a performance improvement by using the if() construct.
I don't know if I understand it correctly, but it seems to me that use
of if() construct with around advice doesn't give me better performance
at all.
Did I miss something? What do you think?
Peter
