Interface GatekeeperWithParams

All Superinterfaces:

Gatekeeper

public interface GatekeeperWithParams
extends Gatekeeper

Specialized Gatekeeper which needs additional parameters in order to find out if the protected Place can be revealed. Example of use:

 public class HasAllRolesGatekeeper implements GatekeeperWithParams {

 private final CurrentUser currentUser;
 private String[] requiredRoles;

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

 @Override
 public GatekeeperWithParams withParams(String[] params) {
 requiredRoles = params;
 return this;
 }

 @Override
 public boolean canReveal() {
 return currentUser.getRoles().containsAll(Arrays.asList(requiredRoles);
 }
 }
 

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

You should usually bind your GatekeeperWithParams as a singleton.
