Class HDIVTilesRequestProcessor

          org.hdiv.tiles.HDIVTilesRequestProcessor

public class HDIVTilesRequestProcessor
extends org.apache.struts.tiles.TilesRequestProcessor

RequestProcessor contains the processing logic that the Struts controller servlet performs as it receives each servlet request from the container.

This processor subclasses the Struts RequestProcessor in order to intercept calls to forward or include. When such calls are done, the Tiles processor checks if the specified URI is a definition name. If true, the definition is retrieved and included. If false, the original URI is included or a forward is performed.

Actually, catching is done by overloading the following methods:

• TilesRequestProcessor.processForwardConfig(HttpServletRequest,HttpServletResponse,ForwardConfig)
• TilesRequestProcessor.internalModuleRelativeForward(String, HttpServletRequest , HttpServletResponse)
• TilesRequestProcessor.internalModuleRelativeInclude(String, HttpServletRequest , HttpServletResponse)
