public interface GridCacheEvictionFilter<K,V>

Eviction filter to specify which entries should not be evicted. Not applicable when calling explicit evict via GridCacheEntry.evict(). If evictAllowed(GridCacheEntry) method returns false then eviction policy will not be notified and entry will never be evicted.

Eviction filter can be configured via GridCacheConfiguration.getEvictionFilter() configuration property. Default value is null which means that all cache entries will be tracked by eviction policy.
