Examples of org.apache.jasper.parser.TreeNode

org.apache.jasper.parser.TreeNode
Simplified implementation of a Node from a Document Object Model (DOM) parse of an XML document. This class is used to represent a DOM tree so that the XML parser's implementation of org.w3c.dom need not be visible to the remainder of Jasper.
WARNING - Construction of a new tree, or modifications to an existing one, are not thread-safe and such accesses must be synchronized. @author Craig R. McClanahan @version $Revision: 1.2 $ $Date: 2001/02/16 22:17:08 $
