Public Methods

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

This implementation delegates to afterCompletion(PortletRequest, PortletResponse, Object, Exception).

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

public void afterEventCompletion (EventRequest request, EventResponse response, Object handler, Exception ex)

This implementation delegates to afterCompletion(PortletRequest, PortletResponse, Object, Exception).

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

public void afterRenderCompletion (RenderRequest request, RenderResponse response, Object handler, Exception ex)

This implementation delegates to afterCompletion(PortletRequest, PortletResponse, Object, Exception).

Parameters
request current portlet render request
response current portlet render response
handler chosen handler to execute, for type and/or instance examination
ex exception thrown on handler execution, if any
Throws
Exception

public void afterResourceCompletion (ResourceRequest request, ResourceResponse response, Object handler, Exception ex)

This implementation delegates to afterCompletion(PortletRequest, PortletResponse, Object, Exception).

Parameters
request current portlet render request
response current portlet render response
handler chosen handler to execute, for type and/or instance examination
ex exception thrown on handler execution, if any
Throws
Exception

public void postHandleRender (RenderRequest request, RenderResponse response, Object handler, ModelAndView modelAndView)

This implementation is empty.

Parameters
request current portlet render request
response current portlet render response
handler chosen handler to execute, for type and/or instance examination
modelAndView the ModelAndView that the handler returned (can also be null)
Throws
Exception

public void postHandleResource (ResourceRequest request, ResourceResponse response, Object handler, ModelAndView modelAndView)

This implementation is empty.

Parameters
request current portlet render request

Parameters
request current portlet action request
