Package org.infinispan.xsite

Class OfflineStatus

java.lang.Object

org.infinispan.xsite.OfflineStatus

All Implemented Interfaces:

CacheEventFilter<Object,Object>

@ThreadSafe
public class OfflineStatus
extends Object
implements CacheEventFilter<Object,Object>

Keeps the state needed for knowing when a site needs to be taken offline.

Thread safety: This class is updated from multiple threads, so the access to it is synchronized by the object's intrinsic lock.

Impl detail: As this class's state changes constantly, the equals and hashCode haven't been overridden. This shouldn't affect performance significantly as the number of site backups should be relatively small (1-3).

Since:

5.2
