类 CopyOnWriteHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

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

com.yomahub.liteflow.util.CopyOnWriteHashMap<K,V>

所有已实现的接口:

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

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

A basic copy on write HashMap.

If an instance is cloned then any methods invoked on the instance or clone that result in state modification will result in copying of the state before modification.
