Class SwitchLayoutController

java.lang.Object
  org.apache.struts.tiles.ControllerSupport
      net.sf.oness.common.webapp.controller.tiles.SwitchLayoutController

All Implemented Interfaces:

org.apache.struts.tiles.Controller

public class SwitchLayoutController

extends org.apache.struts.tiles.ControllerSupport

implements org.apache.struts.tiles.Controller

Tiles controller that checks user-agent header in request and overrides tiles definition attributes.

There is a rule Map in which the key is a string and value is a definition name. If key is contained in user-agent header then all the attributes of the tiles definition are overridden with those of the definition specified as map value and the ones that do not exist are added.

e.g. map contains an entry with "PalmSource" as key and ".layout.palmSourceLayout" as value.
When a browser with "PalmSource" in its user-agent header asks for a page, the definition taken from tiles-defs file will have its attributes plus those from ".layout.palmSourceLayout" definition, overriding the ones that already exist.
