Interface SyncPolicy

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SyncPolicy

Which players receive a Attachment's value. Only players who can see the holder are ever asked: those tracking an entity (plus the entity itself when it's a player), or those with a block entity's chunk loaded.

.sync(SyncPolicy.SELF)                                  // a player's own HUD value
.sync(SyncPolicy.ALL)                                   // everyone who sees the holder, e.g. for rendering
.sync(SyncPolicy.ALL.and((owner, player) -> player.permissions().hasPermission(...)))
