Class WeakKeyValueConcurrentMap<K,V>

java.lang.Object

cn.hutool.core.map.reference.ReferenceConcurrentMap<K,V>

cn.hutool.core.map.reference.WeakKeyValueConcurrentMap<K,V>

Type Parameters:

K - 键类型

V - 值类型

All Implemented Interfaces:

Serializable, Iterable<Map.Entry<K,V>>, ConcurrentMap<K,V>, Map<K,V>

public class WeakKeyValueConcurrentMap<K,V>
extends ReferenceConcurrentMap<K,V>

线程安全的WeakMap实现
键和值都为Weak引用，即，在GC时发现弱引用会回收其对象

Since:

5.8.41
