A class that can determine the weight of an entry.
A listener registered for notification when an entry is evicted.
A class that can determine the weight of a value.
A hash table supporting full concurrency of retrievals, adjustable expected concurrency for updates, and a maximum capacity to bound the map by.
A builder that creates
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.
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. The
concurrency characteristics are those provided by the
ConcurrentHashMap implementation that is
available at runtime.
