Detailed Description

Interface for listening to iteration progress.

This interface is intended to be notified by some progress job, and in particular to the progression of an iteration with an Iterator instance.

It defines 3 methods:

  • init : method called just before the beginning of the iteration
  • finish : method called just after the end of the iteration
  • inc : method called during the iteration; the provided arguments represents the number of iterations before the previous call

Actually, this is a little more than just an interface since it provides empty implementations for the 3 methods; this will ease the development to clients who wants only to get 'inc' notifications but are not interested to do specific actions at the beginning and the end of the iteration.
