Method Detail

preHandleAction

public boolean preHandleAction(ActionRequest request,
                               ActionResponse response,
                               Object handler)
                        throws Exception

This implementation delegates to preHandle.

Specified by:: preHandleAction in interface HandlerInterceptor

Parameters:: request - current portlet action request; response - current portlet action response; handler - chosen handler to execute, for type and/or instance evaluation
Returns:: true if the execution chain should proceed with the next interceptor or the handler itself. Else, DispatcherPortlet assumes that this interceptor has already dealt with the response itself
Throws:: Exception - in case of errors
See Also:: preHandle(javax.portlet.PortletRequest, javax.portlet.PortletResponse, java.lang.Object)

afterActionCompletion

public void afterActionCompletion(ActionRequest request,
                                  ActionResponse response,
                                  Object handler,
                                  Exception ex)
                           throws Exception

This implementation delegates to afterCompletion.

Specified by:: afterActionCompletion in interface HandlerInterceptor

Parameters:: request - current portlet action request; response - current portlet action response; handler - chosen handler to execute, for type and/or instance examination; ex - exception thrown on handler execution, if any (only included as additional context information for the case where a handler threw an exception; request execution may have failed even when this argument is null)
Throws:: Exception - in case of errors
See Also:: afterCompletion(javax.portlet.PortletRequest, javax.portlet.PortletResponse, java.lang.Object, java.lang.Exception)

preHandleRender

public boolean preHandleRender(RenderRequest request,
                               RenderResponse response,
                               Object handler)
                        throws Exception
