public interface RemovalListener<K,V>

An object that can receive a notification when an entry is removed from a cache. The removal resulting in notification could have occured to an entry being manually removed or replaced, or due to eviction resulting from timed expiration, exceeding a maximum size, or garbage collection.

An instance may be called concurrently by multiple threads to process different entries. Implementations of this interface should avoid performing blocking calls or synchronizing on shared resources.
