LinkedMultiValueMap (langx-java 2.8.2 API)

java.lang.Object
- com.jn.langx.util.collection.multivalue.LinkedMultiValueMap<K,V>

类型参数:

K - the key type

V - the value element type

所有已实现的接口:

MultiValueMap<K,V>, Serializable, Cloneable, Map<K,List<V>>
```
public class LinkedMultiValueMap<K,V>
extends Object
implements MultiValueMap<K,V>, Serializable, Cloneable
```
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.

public static final LinkedMultiValueMap EMPTY
```

  - LinkedMultiValueMap
```
public LinkedMultiValueMap()
```
    Create a new LinkedMultiValueMap that wraps a LinkedHashMap.
  - LinkedMultiValueMap
```
public LinkedMultiValueMap(int initialCapacity)
```
    Create a new LinkedMultiValueMap that wraps a LinkedHashMap with the given initial capacity.
    
    参数:
    
    initialCapacity - the initial capacity
  - LinkedMultiValueMap
```
public LinkedMultiValueMap(Map<K,List<V>> otherMap)
```
    Copy constructor: Create a new LinkedMultiValueMap with the same mappings as the specified Map. Note that this will be a shallow copy; its value-holding List entries will get reused and therefore cannot get modified independently.
    
    参数:
    
    otherMap - the Map whose mappings are to be placed in this Map
