I want to display the contents of an NSArray and WORepetition is the
perfect dynamic element to do that. However, I want to complicate
the world and be able to suppress some of the entries based on some
computation performed on each Array element.
It seems I can do this at least two ways:
(1) ... filter the original NSArray through the computation to make a
new NSArray and use that.
(2) ... play games with the processing of the WORepetition so it skips items.
The former isn't hard, obviously, but since WORepetition is already
iterating across all the element of the array, I wonder if the latter
is possible.
I have a *.wod which is, in part:
LoopOverUsers: WORepetition {
list = userList;
item = thisUser;
}
and I have implemented getThisUser / setThisUser methods in the
component, so control passes through these methods for each element
of the array. But is there something I can do to defeat
WORepetition's rendering of some elements ? My guess is NO, but
there are smarter people than I on this list ... thanks, Gavin
