public interface Action<R extends Result>
extends IsSerializable

An action represents a command sent to the Dispatch. It has a specific result type which is returned if the action is successful. Your implementation should override getServiceName() to return a default service url. If you use a SecurityCookie to prevent XSRF attacks and you want this action to be secured against such attacks (i.e. it's not meant to be an anonymous action) then you should override isSecured() to return true.

You can usually inherit from ActionImpl or UnsecuredActionImpl instead.

Method Detail

getServiceName

String getServiceName()

Deprecated.

Access the name of the service, which will be used as the URL path to access the action.

Returns:

The service name.

isSecured

boolean isSecured()

Deprecated.

Verifies if the action is secured. Secured actions perform a number of extra security checks, such as validating the SecurityCookie to foil XSRF attacks.

Important! Make sure your method returns a value that does not depend on client-side information, otherwise it could be tampered with to turn a secure action into an insecure one. An example of a bad practice would be to store a boolean secured member and return that. Since this field is serialized, the user could change it on his side. A simple and good practice is simply to return true; or return false;.

Returns:

true if the action should be secured against XSRF attacks, false otherwise.
