@FunctionalInterface public interface LastPositionFinderA LastPositionFinder is an interface implemented by any SequenceIterator that is able to return the position of the last item in the sequence.
int getLength() throws XPathExceptionGet the last position (that is, the number of items in the sequence). This method is non-destructive: it does not change the state of the iterator. The result is undefined if the next() method of the iterator has already returned null. This method must not be called unless the result of getProperties() on the iterator includes the bit setting
- the number of items in the sequence
XPathException- if an error occurs evaluating the sequence in order to determine the number of items
