  • Method Details

    • changeBy

      default void changeBy(long amount)
      Description copied from interface: Counter
      Changes the counter by the specific amount of units. A positive amount increments the counter, a negative amount decrements the counter.

      The default implementation of this method is to increment or decrement the counter by repeatedly incrementing or decrementing the counter by a single unit via the domain until the desired amount is reached. Implementations are encouraged to override this method with a more efficient implementation if possible.

      Specified by:
      changeBy in interface Counter<Long>
      Parameters:
      amount - The amount to change the counter by.

      The new value of the counter after it was changed.

    • current

      default Long current()
      Description copied from interface: Counter

      Returns:
      The new value of the counter after decrementing.

    • decrementAndGetLong

      default long decrementAndGetLong()
      Decrements the counter by a single unit and returns the new value as a primitive long.
