Package com.j_spaces.kernel

Class SizeConcurrentHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.concurrent.ConcurrentHashMap<K,V>

com.j_spaces.kernel.SizeConcurrentHashMap<K,V>

All Implemented Interfaces:

Serializable, ConcurrentMap<K,V>, Map<K,V>

public class SizeConcurrentHashMap<K,V>
extends ConcurrentHashMap<K,V>

Extends ConcurrentHashMap, keeping AtomicInteger as size counter. Notice that when using clear() the size can be incorrect.
