ConcurrentMap
data structure.
Weigher
is a simple interface for determining how many units of capacity an entry consumes. Depending on which concrete Weigher class is
used, an entry may consume a different amount of space within the cache. The Weighers
class provides utility methods for obtaining the most
common kinds of implementations.
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.
The ConcurrentLinkedHashMap
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.
