Class CollectionValueMap<K,V>

java.lang.Object

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

org.miaixz.bus.core.center.map.multi.AbstractCollValueMap<K,V>

org.miaixz.bus.core.center.map.multi.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>>, MultiValueMap<K,V>, Wrapper<Map<K,Collection<V>>>

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

MultiValueMap的通用实现，可视为值为Collection集合的Map集合。 构建时指定一个工厂方法用于生成原始的Map集合，然后再指定一个工厂方法用于生成自定义类型的值集合。 当调用MultiValueMap中格式为“putXXX”的方法时，将会为key创建值集合，并将key相同的值追加到集合中

Java 17+
