Class NoneOf<M>

  • Type Parameters:
    M - the class of the messages for which this restriction can check allowance
    All Implemented Interfaces:
    Restriction<M>
    public abstract class NoneOf<M>
extends Object
implements Restriction<M>
    A restriction that checks multiple other restrictions none of which may allow a command. To use it, create a trivial subclass of this class and make it a discoverable CDI bean, for example by annotating it with @ApplicationScoped.

    Example: 

    
 @ApplicationScoped
 public class NeitherRoleANorRoleB extends NoneOf<Message> {
     // make bean proxyable according to CDI spec
     public NeitherRoleANorRoleB() {
         super();
     }

     @Inject
     NeitherRoleANorRoleB(RoleA roleA, RoleB roleB) {
         super(roleA, roleB);
     }
 }
