# Package =TWiki::AggregateIterator combine multiple iterators
## new(\\@list, $unique) Create a new iterator over the given list of iterators. The list is not damaged in any way. if $unique is set, we try to not repeat values. Warning: $unique assumes that the values are strings (so works for cUID's ) ## hasNext() -> $boolean Returns false when the iterator is exhausted. my $it = new TWiki::ListIterator(\@list); while ($it->hasNext()) { ... ## next() -> $data Return the next entry in the list. The iterator object can be customised to pre- and post-process entries from the list before returning them. This is done by setting two fields in the iterator object: - `{filter}` can be defined to be a sub that filters each entry. The entry will be ignored (next() will not return it) if the filter returns false. - `{process}` can be defined to be a sub to process each entry before it is returned by next. The value returned from next is the value returned by the process function.
