Method Detail

preHandleAction

public boolean preHandleAction(ActionRequest request,
                               ActionResponse response,

This implementation delegates to preHandle(javax.portlet.PortletRequest, javax.portlet.PortletResponse, java.lang.Object).

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

afterActionCompletion

public void afterActionCompletion(ActionRequest request,
                                  ActionResponse response,
