Re: [aspectj-users] percflow and recursion
|
Another thing that is sometimes appropriate is to make a percflow aspect that is based on a top-level join point (i.e., percflow(pc() && !cflowbelow(pc()))). This gives a common place to hang all the state for any top-level cflow that will always be accessible within the cflow.
But it won't help you if you really want to instantiate a new aspect (e.g., to hold state) for each recursive entry.
Another approach is to use a static ThreadLocal in the aspect (e.g., to hold the Stack that Matthew suggests).
