LinkedMultiValueMap (reactor-core 1.1.6.RELEASE API)

java.lang.Object
- reactor.util.LinkedMultiValueMap<K,V>

Type Parameters:

K - The type of the map's keys

V - The type of the map's values

All Implemented Interfaces:

java.io.Serializable, java.util.Map<K,java.util.List<V>>, MultiValueMap<K,V>
```
public class LinkedMultiValueMap<K,V>
extends java.lang.Object
implements MultiValueMap<K,V>, java.io.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.
