GroupPermissionChangeEvent

Package: com.hypixel.hytale.server.core.event.events.permissions Implements: IEvent<Void> Cancellable: No

Abstract base event for permission changes on a named group. This class is not dispatched directly — its inner classes Added and Removed are the concrete events fired by the permissions system. This event cannot be cancelled — it is a notification of a change that has already occurred.
