      Description copied from interface: LongIterable
      Returns a primitive iterator that can be used to iterate over the LongIterable in an imperative style.

      longIterator in interface LongIterable

    • clear

      void clear()
      Removes all entries from this map.

    • put

      void put(K key, long value)
      Associates a value with the specified key. If a value is already associated with the key in this map, it will be replaced with value.

    • updateValues

      void updateValues(ObjectLongToLongFunction<? super K> function)
