Class HtmlTreeModel

java.lang.Object
org.htmlparser.parserapplications.filterbuilder.HtmlTreeModel
All Implemented Interfaces:
TreeModel
public class HtmlTreeModel extends Object implements TreeModel
Quick and dirty tree model for HTML nodes.

  • Field Details

    • mTreeListeners

      protected Vector mTreeListeners
      The list of tree listeners.

    • mRoot

      protected Node mRoot

    • HtmlTreeModel

      public HtmlTreeModel(NodeList root)
      Create an HTML tree view.
      Parameters:
      root - The nodes at the root of the tree (the nodes are wrapped in an Html node that is never seen because it's the root, but this makes all downstream processing super-simple because every tree node is then a Node, not sometimes a NodeList at the root).
