    • Method Detail

      • next

        public int next()
        Description copied from interface: DTMAxisIterator
        Get the next node in the iteration.
        Returns:
        The next node handle in the iteration, or END.

      • setStartNode

        public DTMAxisIterator setStartNode​(int node)
        Description copied from interface: DTMAxisIterator
        Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.
        Parameters:
        node - Sets the root of the iteration.
        Returns:
        A DTMAxisIterator set to the start of the iteration.

      • getLast

        public int getLast()
        Description copied from class: DTMAxisIteratorBase
        Returns the position of the last node within the iteration, as defined by XPath. In a forward iterator, I believe this equals the number of nodes which this iterator will yield. In a reverse iterator, I believe it should return 1 (since the "last" is the first produced.) This may be an expensive operation when called the first time, since it may have to iterate through a large part of the document to produce its answer.
        Specified by:
        getLast in interface DTMAxisIterator
        Overrides:
        getLast in class DTMAxisIteratorBase
        Returns:
        The number of nodes in this iterator (forward) or 1 (reverse).

      • setMark

        public void setMark()
        Description copied from interface: DTMAxisIterator
        Remembers the current node for the next call to gotoMark().

      • gotoMark

        public void gotoMark()
        Description copied from interface: DTMAxisIterator
        Restores the current node remembered by setMark().
