Thanks for the help, Monty.
I just have one other dumb question that is causing me difficulty at the
moment, can anyone help?
Say I have some structure like this:
pointcut1 && pointcut2 && pointcut3
(yadda yadda)
Currently my grammar is something like (yes, what I'm showing here is
broken... it's somewhere between what I had and what I want!):
pointcut
: pointcuts (binaryPointcut)*
;
pointcuts
: "execution" LPAREN! functionSig RPAREN! body
{ ## = #(NPointcut, ##); }
;
binaryPointcut
: binaryPointcutOp^ pointcuts
{ ## = #(NPointcut, ##); }
;
binaryPointcutOp
: LAND
| LOR
;
for reasons of simplicity in my aspect weaver, I want to turn the "&&" into a
type of pointcut itself-- basically I want to create
andPointcut(andPointcut(pointcut1, pointcut2), pointcut3) (I *think* that's
the right order of operations?)./
I'm really stuck in a LALR world right now in my head, and I can easily come
up with a yacc solution. :) Does anyone know the ANTLR way to do this?
thanks!
