Re: [aspectj-dev] thisJoinPoint and if() Performance
|
Compile it with -XlazyTjp (which is soon to become default) and you will
see it compiles to:
invokestatic #66; //Method ajc$if_0:()Z
invokestatic #62; //Method aspectOf:()LX;
[...]
invokestatic #60; //Method
org/aspectj/runtime/reflect/Factory.makeJP:(Lorg/aspectj/lang/JoinPoint$StaticPart
;Ljava/lang/Object;Ljava/lang/Object;)Lorg/aspectj/lang/JoinPoint;
invokevirtual #64; //Method
ajc$before$X$1$681c4445:(Lorg/aspectj/lang/JoinPoint;)V

if() Performance

Hi all,
is there a reason why following pointcut & advice
before() : execution(* BlaBla.*(..)) && if (someCondition) {
JoinPoint jp = thisJoinPoint;
}
is translated (in bytecode) to something like:
[...]
invokestatic <org/aspectj/runtime/reflect/Factory.makeJP>
[...]
invokestatic <...$if_0>
Invoking ...$if_0 before getting the Joinpoint makes more sense in my
opinion and furthermore would increase performance (in case of
SomeCondition = false) dramatically.
Regards,
Simon
