类 LinkedMultiValueMap<K,​V>

构造器详细资料

• 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
