| org.springframework.web.portlet.HandlerAdapter
All known Subclasses: org.springframework.web.portlet.mvc.SimpleControllerHandlerAdapter, org.springframework.web.portlet.handler.SimplePortletHandlerAdapter,
| HandlerAdapter | | public interface HandlerAdapter (Code) | | Portlet MVC framework SPI interface, allowing parameterization of core MVC workflow.
Interface that must be implemented for each handler type to handle a request.
This interface is used to allow the DispatcherPortlet to be indefinitely
extensible. The DispatcherPortlet accesses all installed handlers through this
interface, meaning that it does not contain code specific to any handler type.
Note that a handler can be of type Object. This is to enable handlers from
other frameworks to be integrated with this framework without custom coding.
This interface is not intended for application developers. It is available
to handlers who want to develop their own web workflow.
Note: Implementations can implement the Ordered interface to be able to
specify a sorting order and thus a priority for getting applied by
DispatcherPortlet. Non-Ordered instances get treated as lowest priority.

handler - handler to use. | | ModelAndView | handleRender(RenderRequest request, RenderResponse response, Object handler)
Use the given handler to handle this render request.
The workflow that is required may vary widely.
Parameters:
request - current render request
Parameters:
response - current render response
Parameters:
handler - handler to use. | | boolean | supports(Object handler)
Given a handler instance, return whether or not this HandlerAdapter can
support it. |
| handleAction | | void handleAction(ActionRequest request, ActionResponse response, Object handler) throws Exception(Code) | | Use the given handler to handle this action request.
The workflow that is required may vary widely.
Parameters:
request - current action request
Parameters:
response - current action response
Parameters:
handler - handler to use. This object must have previously been passedto the supports method of this interface, which must havereturned true.
throws:
Exception - in case of errors |
| handleRender | | ModelAndView handleRender(RenderRequest request, RenderResponse response, Object handler) throws Exception(Code) | | Use the given handler to handle this render request.
The workflow that is required may vary widely.
Parameters:
request - current render request
Parameters:
response - current render response
Parameters:
handler - handler to use. This object must have previously been passedto the supports method of this interface, which must havereturned true.
throws:
Exception - in case of errors ModelAndView object with the name of the view and the requiredmodel data, or null if the request has been handled directly |
| supports | | boolean supports(Object handler)(Code) | | 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);
Parameters:
handler - handler object to check whether or not this object can use the given handler
