    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      NodePointer getNodePointer()
      Get the NodePointer at the current position.
      int getPosition()
      Get the current iterator position.
      private boolean next()
      Iterate to next pointer.
      private boolean previous()
      This is actually never invoked during the normal evaluation of xpaths - an iterator is always going forward, never backwards.
      boolean setPosition​(int position)
      Set the new current position.
      private boolean testChild()
      Test a child node.

      • JDOMNodeIterator

        public JDOMNodeIterator​(NodePointer parent,
                                NodeTest nodeTest,
                                boolean reverse,
                                NodePointer startWith)
        Create a new JDOMNodeIterator.
        Parameters:
        parent - pointer
        nodeTest - test
        reverse - whether to iterate in reverse
        startWith - starting pointer

      • getPosition

        public int getPosition()
        Description copied from interface: NodeIterator
        Get the current iterator position.
        Specified by:
        getPosition in interface NodeIterator
        Returns:
        int position
      • setPosition

        public boolean setPosition​(int position)
        Description copied from interface: NodeIterator
        Set the new current position.
        Specified by:
        setPosition in interface NodeIterator
        Parameters:
        position - the position to set
        Returns:
        true if there is a node at position.
      • previous

        private boolean previous()
        This is actually never invoked during the normal evaluation of xpaths - an iterator is always going forward, never backwards. So, this is implemented only for completeness and perhaps for those who use these iterators outside of XPath evaluation.
        Returns:
        boolean
      • next

        private boolean next()
        Iterate to next pointer.
        Returns:
        whether valid
      • testChild

        private boolean testChild()
        Test a child node.
        Returns:
        whether test passes.
