      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 float addTo(T key, float value)

      public float subFrom(T key, float value)
      Beschreibung aus Schnittstelle kopiert: Object2FloatMap

      Gibt zurück:
      the last present or default return value
