Class ListValueMap<K,V>

java.lang.Object

org.aoju.bus.core.map.MapWrapper<K,Collection<V>>

org.aoju.bus.core.map.multi.CollectionValueMap<K,V>

org.aoju.bus.core.map.multi.ListValueMap<K,V>

Type Parameters:

K - 键类型

V - 值类型

All Implemented Interfaces:

Serializable, Cloneable, Iterable<Map.Entry<K,Collection<V>>>, Map<K,Collection<V>>

public class ListValueMap<K,V>
extends CollectionValueMap<K,V>

值作为集合List的Map实现,通过调用putValue可以在相同key时加入多个值,多个值用集合表示

Since:

JDK 1.8+

Version:

6.0.2
