## org.jasig.portal.car
Class RoutingHandler

    java.lang.Object
      org.xml.sax.helpers.DefaultHandler
          org.jasig.portal.car.RoutingHandler

All Implemented Interfaces:
  org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

    public class RoutingHandler

extends org.xml.sax.helpers.DefaultHandler

Handles routing events to a registered set of handlers that each handles different portions of the descriptors xml tree. For example, a services block and all events for its top level services tag and any nested elements would be routed to the handler for services. This object also keeps track of the full traversal path from an element back to the containing document object.
