java.lang.Objectorg.springframework.util.LinkedMultiValueMap<K,V>
public class LinkedMultiValueMap<K,V>
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.
