Constructor Detail

FacesControllerHandlerAdapter

public FacesControllerHandlerAdapter()

Method Detail

supports

public boolean supports(java.lang.Object handler)

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

getLastModified

public long getLastModified(javax.servlet.http.HttpServletRequest request,
                            java.lang.Object handler)

Same contract as for HttpServlet's getLastModified method. Can simply return -1 if there's no support in the handler class.

Specified by:

getLastModified in interface HandlerAdapter

Parameters:

request - current HTTP request

handler - handler to use

Returns:

the lastModified value for the given handler

                           javax.servlet.http.HttpServletResponse response,
                           java.lang.Object handler)
                    throws java.lang.Exception

Use the given handler to handle this request. The workflow that is required may vary widely.

Specified by:

handle in interface HandlerAdapter

Parameters:

request - current HTTP request

response - current HTTP response

handler - handler to use. This object must have previously been passed to the supports method of this interface, which must have returned true.

ModelAndView object with the name of the view and the required model data, or null if the request has been handled directly

Throws:
