Re: [aspectj-users] Updating variable in the middle of a method

[Simone Gianni <simoneg@xxxxxxxxxx>]

Hi Breaks,
you can use an around advice :

pointcut executionOfMyMethod() : execution(public StringBuffer
TheClass.myMethod());

Object around() : executionOfMyMethod() {
  StringBuffer sb = new StringBuffer();
  sb.append(123);
  return sb;
}

There is no way to access a variable declared inside a method.

This also relates to your next question.

Hope this helps,
Simone
