Interface ICacheListener<K extends Serializable,V extends Serializable>

All Known Subinterfaces:

ILateralCacheListener<K,V>, IRemoteCacheListener<K,V>

All Known Implementing Classes:

AbstractDiskCache.MyCacheListener, AbstractRemoteCacheListener, CacheAdaptor, LateralTCPListener, RemoteCacheListener, RemoteHttpClientListener

public interface ICacheListener<K extends Serializable,V extends Serializable>

Used to receive a cache event notification.

Note: objects which implement this interface are local listeners to cache changes, whereas objects which implement IRmiCacheListener are remote listeners to cache changes.
