public interface ActionHandler

This interface adds a feature to Actions needed by all the various contexts. The ServletModule.RequestListener is a little too generic for more complicated handler resolution. Thus actions should generally try to also implement this interface. Actions that don't implement this interface cannot be used in context derived from GenericContext unless the checkActions parameter of the context is set to false.

Method Detail

isHandleAction

boolean isHandleAction(javax.servlet.http.HttpServletRequest req,
                       javax.servlet.http.HttpServletResponse resp,
                       ModulesServlet.HttpMethod method)

Checks if this action handler will try to handle the given action without handling it yet or causing any side effects. Returning true means that the action handler will try to handle it, not necessarily that the action will succeed. You may also return false from the handleRequest method even if you return true here. The return value should be your best guess as to whether you will handle it without spending too much time checking.

Parameters:

req - The HTTP request.

resp - The HTTP response.

method - The HTTP method of the request.

Returns:
