java.lang.Object java.lang.Enum<NotificationScope> javax.cache.event.NotificationScope
public enum NotificationScope
This enumeration defines valid values for CacheEntryListener
notification scope.
A distributed cache may contain multiple CacheManager nodes. Events on a cache instance inside
in the same JVM are considered local, other events are not.
CacheEntryListener
with a remote notification scope.
Only those cluster members interested in receiving remote events should register such a listener.
There can be a large cost difference between receipt of local versus remote events thus allowing the choice.
Accordingly, the remote notification scope is optional. This capability can be determined using Caching.isSupported(javax.cache.OptionalFeature)
.
