      public short put(double key, short value)
      Beschreibung aus Schnittstelle kopiert: Double2ShortMap
      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 short addTo(double key, short value)
      Beschreibung aus Schnittstelle kopiert: Double2ShortMap
      A Helper method to add a primitives together. If key is not present then this functions as a put.
      Parameter:

      value - the value that should be inserted / added
      Gibt zurück:
      the last present value or default return value.

    • subFrom

      public short subFrom(double key, short value)
      Beschreibung aus Schnittstelle kopiert: Double2ShortMap
      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
