Class SetValueMap<K,V>

java.lang.Object

org.dromara.hutool.core.map.MapWrapper<K,Collection<V>>

org.dromara.hutool.core.map.multi.AbsCollValueMap<K,V>

org.dromara.hutool.core.map.multi.SetValueMap<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>>, Wrapper<Map<K,Collection<V>>>, MultiValueMap<K,V>

Direct Known Subclasses:

public class SetValueMap<K,V>
extends AbsCollValueMap<K,V>

值作为集合Set（LinkedHashSet）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
