ConcurrentMap data structure.
EvictionListener provides the
ability to be notified when an entry is evicted from the map. An eviction
occurs when the entry was automatically removed due to the map exceeding a
capacity threshold. It is not called when an entry was explicitly removed.
class supplies an efficient, scalable, thread-safe, bounded map. As with the
Java Collections Framework the "Concurrent" prefix is used to
indicate that the map is not governed by a single exclusion lock.
