Class LinkedMultiValueMap<K,V>

Type Parameters:
K - the key type
V - the value element type
All Implemented Interfaces:
Serializable, Cloneable, Map<K,List<V>>, MultiValueMap<K,V>

public class LinkedMultiValueMap<K,V> extends MultiValueMapAdapter<K,V> implements Serializable, Cloneable
Simple implementation of MultiValueMap that wraps a LinkedHashMap, storing multiple values in an ArrayList.

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 LinkedMultiValueMap()
      Create a new LinkedMultiValueMap that wraps a LinkedHashMap.

      public LinkedMultiValueMap(int expectedSize)
      Create a new LinkedMultiValueMap that wraps a LinkedHashMap with an initial capacity that can accommodate the specified number of elements without any immediate resize/rehash operations to be expected.
      expectedSize - the expected number of elements (with a corresponding capacity to be derived so that no resize/rehash operations are needed)

      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.
      otherMap - the Map whose mappings are to be placed in this Map
