Detailed Description

A safe iterator of lists.

Library: ilog

This class is generated by the macro IlDefineListOf(NAME, TYPE).
It is similar to (and derives from, in a hidden manner) IlListIteratorOf(NAME), but has the advantage of letting the user modify the list (even destroy it) while you are iterating its elements.

IlListOf(NAME).
