Examples of net.sf.saxon.evpull.EventMappingIterator

net.sf.saxon.evpull.EventMappingIterator
MappingIterator merges a sequence of sequences into a single sequence. It takes as inputs an iteration, and a mapping function to be applied to each Item returned by that iteration. The mapping function itself returns another iteration. The result is an iteration of iterators. To convert this int a single flat iterator over a uniform sequence of events, the result must be wrapped in an {@link EventStackIterator}

        // expression, wrapped in an EventMappingAction object that is responsible also for
        // setting the range variable at each step.


        SequenceIterator base = sequence.iterate(context);
        EventMappingFunction map = new EventMappingAction(context, getLocalSlotNumber(), positionVariable, action);
        return new EventMappingIterator(base, map);
    }
