Just to recap... What exactly does the function GetEnumerator return? Specifically for list type classes. Also what interface would that enumerator support? The reason I ask... I would still like the full power of Iterator (as discussed before) for all List type classes in the RTL (similar to my code attachment of 4 days ago). I'm not sure if what you implemented will conflict with what I want to implement in the RTL. The major difference would be that mine is a implementation detail in the list classes, whereas your implementation is a language feature. When I use iterators, I would like to have the ability to use Current, HasNext, HasPrevious, PeakNext, PeakPrevious, Reset, JumpToBack, pass a filter to GetIterator... etc. Also, I referred to them in my implementation as Iterators - as per the Iterator design pattern. How does Enumerator differ from Iterator? -- Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
