iterators: traversing arbitrary data structureby dimar (Curate)
|on Jan 11, 2006 at 20:35 UTC||Need Help??|
dimar has asked for the wisdom of the Perl Monks concerning the following question:
Given a data structure like this ...
How can I change this ...
into this ...
I've given SuperSearch a say, but it seems the examples assume a simple sequence of items (e.g. array), when what I want to do is iterate over an arbitrarily-nested data structure. (e.g. HoAoH)
My long term goal is to be able to reproduce this pattern regardless of the structure of the data variable. The request here is for a link or an example of handling HoAoH with iterators that I can use as a starting point for understanding this design pattern a little better.
