Authorizers

An authorizer checks whether or not an actor has permission to call a certain command.

Registering

To register an authorizer, you first need to construct a ParametricBuilder. The setAuthorizer() method simply takes one parameter: your authorizer implementation.

builder.setAuthorizer(new ActorAuthorizer());

Implementing an authorizer

The Authorizer interface only requires you to implement one method; the testPermission() method. The method has two parameters: the namespace of the command and the permission.

A simple authorizer for e.g. Bukkit might look like this:

public class BukkitAuthorizer implements Authorizer {

    @Override
    public boolean testPermission(Namespace namespace, String perm) {
        return namespace.get(CommandSender.class).hasPermission(perm);
    }

}

Note: Remember to put your actor in the namespace when calling your command.
