Re: Question for using ASM to log the method invocation trace.

Zhongxian.

I do not quite understand your question

Normally, you need to write a wrapper class for instrumentation, like:

class Tracer {

    public static void record(String str) {
          BufferWriter = ..
          //write to the file, and close here
    }
}

What you need to do is to insert *Tracer.record(xx) *to the right place. You
do
not need to deal with where to flush, close the stream, right?


Hope it helps.
