Class LinkedMultiValueMap<K,​V>

  • All Implemented Interfaces:
    MultiValueMap<K,​V>, java.io.Serializable, java.lang.Cloneable, java.util.Map<K,​java.util.List<V>>
    public class LinkedMultiValueMap<K,​V>
extends java.util.LinkedHashMap<K,​java.util.List<V>>
implements MultiValueMap<K,​V>, java.io.Serializable

    This class is a clone of org.springframework.util.LinkedMultiValueMap

    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.

    • Constructor Detail

      • 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.
        Parameters:
        initialCapacity - the initial capacity

      • LinkedMultiValueMap

        public LinkedMultiValueMap​(java.util.Map<K,​java.util.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.
        Parameters:
        otherMap - the Map whose mappings are to be placed in this Map
