org.springframework.util
Class LinkedMultiValueMap<K,V>

java.lang.Object
  org.springframework.util.LinkedMultiValueMap<K,V>

All Implemented Interfaces:: Serializable, Map<K,List<V>>, MultiValueMap<K,V>

public class LinkedMultiValueMap<K,V>
extends Object
implements MultiValueMap<K,V>, Serializable
extends Object
implements MultiValueMap<K,V>, Serializable

Simple implementation of MultiValueMap that wraps a LinkedHashMap, storing multiple values in a LinkedList.

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.

Since:: 3.0
