      public float put(float key, float value)
      Beschreibung aus Schnittstelle kopiert: Float2FloatMap
      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 float addTo(float key, float value)
      Beschreibung aus Schnittstelle kopiert: Float2FloatMap

      public float subFrom(float key, float value)
      Beschreibung aus Schnittstelle kopiert: Float2FloatMap

      the last present or default return value
