Class RWLockedMap<K,V>

java.lang.Object

org.everit.transaction.map.readcommited.internal.RWLockedMap<K,V>

Type Parameters:

K - The type of the keys.

V - The type of the values.

All Implemented Interfaces:

Map<K,V>

public class RWLockedMap<K,V>
extends Object
implements Map<K,V>

A Map implementation that uses ReadWriteLock in its functions. Beware that this class does not override the functions introduced in Java 8 as this class was designed to be used internally within Managed Map project.
