类 DefaultMultiValueMap<K,V>

java.lang.Object
cn.taketoday.util.DefaultMultiValueMap<K,V>
类型参数:
K - the key type
V - the value element type
所有已实现的接口:
ArraySizeTrimmer, MultiValueMap<K,V>, Serializable, Cloneable, Map<K,List<V>>
直接已知子类:
LinkedMultiValueMap
public class DefaultMultiValueMap<K,V> extends Object implements MultiValueMap<K,V>, Serializable, Cloneable, ArraySizeTrimmer
Simple implementation of MultiValueMap that wraps a Map, storing multiple values in a List. Can Specify a mappingFunction to determine which List you use , default is ArrayList

This Map implementation is generally not thread-safe. It is primarily designed for data structures exposed from request objects, for use in a single thread only.
