      • get

        public final short get()
        Return the current value
      • set

        public short set​(short newValue)
        Set to newValue.
        Returns:
        the old value
      • commit

                              short newValue)
        Set value to newValue only if it is currently assumedValue.
        Returns:
        true if successful
      • swap

        public short swap​(SynchronizedShort other)
        Atomically swap values with another SynchronizedShort. Uses identityHashCode to avoid deadlock when two SynchronizedShorts attempt to simultaneously swap with each other. (Note: Ordering via identyHashCode is not strictly guaranteed by the language specification to return unique, orderable values, but in practice JVMs rely on them being unique.)
        Returns:
        the new value
      • increment

        public short increment()
        Increment the value.
        Returns:
        the new value
      • decrement

        public short decrement()
        Decrement the value.
        Returns:
        the new value
      • add

        public short add​(short amount)
        Add amount to value (i.e., set value += amount)
        Returns:
        the new value
      • subtract

        public short subtract​(short amount)
        Subtract amount from value (i.e., set value -= amount)
        Returns:
