      public int put(short key, int value)
      Beschreibung aus Schnittstelle kopiert: Short2IntMap
      Type Specific method to reduce boxing/unboxing of values
      Parameter:
      key - the key that should be inserted,
      value - the value that should be inserted
      Gibt zurück:
      the last present value or default return value.

    • addTo

      public int addTo(short key, int value)
      Beschreibung aus Schnittstelle kopiert: Short2IntMap

      public int subFrom(short key, int value)
      Beschreibung aus Schnittstelle kopiert: Short2IntMap
