Constructor Detail

### SimpleControllerHandlerAdapter

    public SimpleControllerHandlerAdapter()

Method Detail

### setPortletContext

    public void setPortletContext(PortletContext portletContext)

  Description copied from interface: `PortletContextAware`
  Set the PortletContext that this object runs in.

  Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.

  Specified by:
    `setPortletContext` in interface `PortletContextAware`
  Parameters:
    `portletContext` - PortletContext object to be used by this object

### supports

    public boolean supports(Object handler)

  Description copied from interface: `HandlerAdapter`
  Given a handler instance, return whether or not this HandlerAdapter can support it. Typical HandlerAdapters will base the decision on the handler type. HandlerAdapters will usually only support one handler type each.

  A typical implementation:

  `return (handler instanceof MyHandler);`

  Specified by:
    `supports` in interface `HandlerAdapter`
  Parameters:
    `handler` - handler object to check
  Returns:
    whether or not this object can use the given handler

### handleAction

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

  Description copied from interface: `HandlerAdapter`
  Use the given handler to handle this action request. The workflow that is required may vary widely.

  Specified by:
    `handleAction` in interface `HandlerAdapter`
  Parameters:
    `request` - current action request
    `response` - current action response
    `handler` - handler to use. This object must have previously been passed to the `supports` method of this interface, which must have returned true.
  Throws:
    `Exception` - in case of errors
  See Also:
    `Portlet.processAction(javax.portlet.ActionRequest, javax.portlet.ActionResponse)`

### handleRender

    public ModelAndView handleRender(RenderRequest request,
                                     RenderResponse response,
                                     Object handler)
                              throws Exception

  Description copied from interface: `HandlerAdapter`
  Use the given handler to handle this render request. The workflow that is required may vary widely.

  Specified by:
    `handleRender` in interface `HandlerAdapter`
  Parameters:
    `request` - current render request
    `response` - current render response
    `handler` - handler to use. This object must have previously been passed to the `supports` method of this interface, which must have returned `true`.
  Returns:
    ModelAndView object with the name of the view and the required model data, or `null` if the request has been handled directly
  Throws:
    `Exception` - in case of errors
  See Also:
    `Portlet.render(javax.portlet.RenderRequest, javax.portlet.RenderResponse)`

### handleResource

    public ModelAndView handleResource(ResourceRequest request,
                                       ResourceResponse response,
                                       Object handler)
                                throws Exception

  Description copied from interface: `HandlerAdapter`
  Use the given handler to handle this resource request. The workflow that is required may vary widely.

  Specified by:
    `handleResource` in interface `HandlerAdapter`
  Parameters:
