public class LinkedMultiValueMap<K,V> extends Object implements MultiValueMap<K,V>, Serializable, Cloneable
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.
| Constructor and Description |
|---|
LinkedMultiValueMap()
Create a new LinkedMultiValueMap that wraps a
LinkedHashMap. |
LinkedMultiValueMap(int initialCapacity)
Create a new LinkedMultiValueMap that wraps a
LinkedHashMap
with the given initial capacity. |
LinkedMultiValueMap(Map<K,List<V>> otherMap)
Copy constructor: Create a new LinkedMultiValueMap with the same mappings as
the specified Map.
