      public long put(T key, long value)
      Beschreibung aus Schnittstelle kopiert: Object2LongMap
      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(T key, long value)
      Beschreibung aus Schnittstelle kopiert: Object2LongMap

      the last present or default return value
