      public long put(short key, long value)
      Beschreibung aus Schnittstelle kopiert: Short2LongMap
      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 long addTo(short key, long value)
      Beschreibung aus Schnittstelle kopiert: Short2LongMap
      A Helper method to add a primitives together. If key is not present then this functions as a put.

      public long subFrom(short key, long value)
      Beschreibung aus Schnittstelle kopiert: Short2LongMap
      A Helper method to subtract from primitive from each other.

      key - that should be subtract from

      Gibt zurück:
      the last present or default return value
