      public char put(byte key, char value)
      Beschreibung aus Schnittstelle kopiert: Byte2CharMap
      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 char addTo(byte key, char value)
      Beschreibung aus Schnittstelle kopiert: Byte2CharMap
      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:

    • subFrom

      public char subFrom(byte key, char value)
      Beschreibung aus Schnittstelle kopiert: Byte2CharMap
      A Helper method to subtract from primitive from each other.

      the last present or default return value
