Package org.aoju.bus.core.map

Class CollectionValueMap<K,V>

java.lang.Object

org.aoju.bus.core.map.MapWrapper<K,C>

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

org.aoju.bus.core.map.CollectionValueMap<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>>, XWrapper<Map<K,Collection<V>>>

public class CollectionValueMap<K,V>
extends AbstractCollValueMap<K,V,Collection<V>>

值作为集合的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:

Java 17+
