org.jaxen.dom.DocumentNavigator.NodeIterator
All Implemented Interfaces:
Iterator
Enclosing class:
DocumentNavigator
abstract class DocumentNavigator.NodeIterator extends Object implements Iterator
A generic iterator over DOM nodes.

Concrete subclasses must implement the getFirstNode(Node) and getNextNode(Node) methods for a specific iteration strategy.

  • Field Details

      private Node node

  • Constructor Details

    • NodeIterator

      public NodeIterator(Node contextNode)
      Constructor.
      Parameters:
      contextNode - the starting node

  • Method Details

    • hasNext

      public boolean hasNext()
      Specified by:
      hasNext in interface Iterator

    • next

      public Object next()
      Specified by:
      next in interface Iterator

    • remove

      public void remove()
      Specified by:
      remove in interface Iterator

    • getFirstNode

      protected abstract Node getFirstNode(Node contextNode)
      Get the first node for iteration.

      This method must derive an initial node for iteration from a context node.

      Parameters:
      contextNode - the starting node
      Returns:
      the first node in the iteration

    • getNextNode

      protected abstract Node getNextNode(Node contextNode)
      Get the next node for iteration.

      This method must locate a following node from the current context node.

      Parameters:
      contextNode - the current node in the iteration
      Returns:
      the following node in the iteration, or null if there is none

    • isXPathNode

      private boolean isXPathNode(Node node)
      Test whether a DOM node is usable by XPath.
      Parameters:
      node - the DOM node to test
      Returns:
      true if the node is usable, false if it should be skipped
