Class ScreenPositionInterceptor

java.lang.Object
  org.springframework.web.servlet.handler.HandlerInterceptorAdapter
      net.sf.springlayout.web.interceptor.ScreenPositionInterceptor

All Implemented Interfaces:

org.springframework.web.servlet.HandlerInterceptor

public class ScreenPositionInterceptor
extends org.springframework.web.servlet.handler.HandlerInterceptorAdapter

Checks an incoming request for the WebConstants.SCREEN_POSITION_PARAM parameter and passes to the next request via the session and sets as a request attribute in order to survive a redirect. The WebConstants.SCREEN_POSITION_PARAM is set by the ui when a postback is submitted to pass the current screen position to the resulting screen so it can be reopened in the same position.
