      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
      A Helper method to add a primitives together. If key is not present then this functions as a put.
      Parameter:
      key - the key that should be inserted,
      value - the value that should be inserted / added
      Gibt zurück:
      the last present value or default return value.

    • subFrom

      public long subFrom(T key, long value)
      Beschreibung aus Schnittstelle kopiert: Object2LongMap
      A Helper method to subtract from primitive from each other. If the key is not present it will just return the defaultValue How the implementation works is that it will subtract from the current value (if not present it will do nothing) and fence it to the Object2LongMap.getDefaultReturnValue() If the fence is reached the element will be automaticall removed

      key - that should be subtract from

      the last present or default return value
