Interface Gatekeeper

All Known Subinterfaces:

GatekeeperWithParams

public interface Gatekeeper

Inherit from this class to define a gatekeeper that locks access to your Place in specific situation. For example:

 public class AdminGatekeeper implements Gatekeeper {

   private final CurrentUser currentUser;

  @Inject
   public AdminGatekeeper( CurrentUser currentUser ) {
     this.currentUser = currentUser;
   }

  @Override
   public boolean canReveal() {
     return currentUser.isAdministrator();
   }

 }
 

You must also make sure that your custom Ginjector provides a get method returning this Gatekeeper if you want to use it with the UseGatekeeper annotation.

You should usually bind your Gatekeeper as a singleton.
