      boolean put(K key, V value)
      Stores a key-value pair in the multimap.
      Specified by:
      put in interface BaseMultiMap<K,V>
      Parameters:
      key - the key to be stored
      value - the value to be stored
      Returns:
      true if the size of the multimap is increased, false if the multimap already contains the key-value pair.

    • get

      Collection<V> get(K key)
      Returns the collection of values associated with the key.
      Specified by:
      get in interface BaseMultiMap<K,V>
      Parameters:
      key - the key whose associated values are returned
      Returns:
      the collection of the values associated with the key

    • remove

      boolean remove(Object key, Object value)
      Removes the given key value pair from the multimap.
      Specified by:
      remove in interface BaseMultiMap<K,V>
      Parameters:
      key - the key of the entry to remove
      value - the value of the entry to remove
