new EnumSet()
EnumSet is an abstract Java class. Do not instantiate it and use its static methods instead.
Example
In this simple example we create a Room, setting its permissions by means of an EnumSet.
var crs = new CreateRoomSettings();
crs.setName("chat#371");
crs.setMaxUsers(10);
// Set Room permissions
crs.setRoomSettings(EnumSet.of(SFSRoomSettings.USER_ENTER_EVENT, SFSRoomSettings.USER_EXIT_EVENT, SFSRoomSettings.PUBLIC_MESSAGES));
// Create the Room
getApi().createRoom(getParentZone(), crs, null, false, null, true, true);
