Method Detail

getReverseIterator

SequenceIterator<T> getReverseIterator()

Get a new SequenceIterator that returns the same items in reverse order. If this SequenceIterator is an AxisIterator, then the returned SequenceIterator must also be an AxisIterator.

Returns:

an iterator over the items in reverse order
