Class SelfInitializingConcurrentHashMap<K,V>

java.lang.Object
  org.jboss.cache.util.concurrent.SelfInitializingConcurrentHashMap<K,V>

All Implemented Interfaces:

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

public class SelfInitializingConcurrentHashMap<K,V>
extends Object
implements ConcurrentMap<K,V>

Primarily used to hold child maps for nodes. Underlying CHM is null initially, and once threads start writing to this map, the CHM is initialized.

Since:

3.0
