Interface CacheCoherence

public interface CacheCoherence

Permits to implement a cache coherence protocol.

Coherent caches created using CacheManager.createCoherentCache(String) will notify an instace which is registered for this interface once a key needs to be removed or if the cache is entirely cleared.

The coherence implementation must broadcast this information to all nodes of a cluster and call CacheManager.clearCoherentCacheLocally(String) or CacheManager.removeCoherentCacheKeyLocally(String, String) locally on each node.
