/**
* This package contains an implementation of a bounded
* {@link java.util.concurrent.ConcurrentMap} data structure.
*
* {@link org.apache.groovy.util.concurrentlinkedhashmap.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
* {@link org.apache.groovy.util.concurrentlinkedhashmap.Weighers} class provides
* utility methods for obtaining the most common kinds of implementations.
*
* {@link org.apache.groovy.util.concurrentlinkedhashmap.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 {@link org.apache.groovy.util.concurrentlinkedhashmap.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.
*
* @see
* http://code.google.com/p/concurrentlinkedhashmap/
