类 ConcurrentHashMapV8.KeySetView<K,V>

java.lang.Object

org.skfiy.util.v8.ConcurrentHashMapV8.KeySetView<K,V>

所有已实现的接口:

Serializable, Iterable<K>, Collection<K>, Set<K>

封闭类:

ConcurrentHashMapV8<K,V>

public static class ConcurrentHashMapV8.KeySetView<K,V>
extends Object
implements Set<K>, Serializable

A view of a ConcurrentHashMapV8 as a Set of keys, in which additions may optionally be enabled by mapping to a common value. This class cannot be directly instantiated. See null null null null null ConcurrentHashMapV8.keySet(), ConcurrentHashMapV8.keySet(Object), ConcurrentHashMapV8.newKeySet(), ConcurrentHashMapV8.newKeySet(int).
