      • SynchronizedByte

        public SynchronizedByte​(byte initialValue)

    • Method Detail

      • get

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

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

        public boolean commit​(byte assumedValue,
                              byte newValue)
        Set value to newValue only if it is currently assumedValue.
        Returns:
        true if successful
      • swap

        public byte swap​(SynchronizedByte other)
        Atomically swap values with another SynchronizedByte. Uses identityHashCode to avoid deadlock when two SynchronizedBytes 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 byte increment()
        Increment the value.
        Returns:
        the new value
      • decrement

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

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

        public byte subtract​(byte amount)
        Subtract amount from value (i.e., set value -= amount)
        Returns:
        the new value
      • multiply

        public byte multiply​(byte factor)
        Multiply value by factor (i.e., set value *= factor)
        Returns:
        the new value
      • divide

        public byte divide​(byte factor)
        Divide value by factor (i.e., set value /= factor)
        Returns:
        the new value
      • negate

        public byte negate()
        Set the value to the negative of its old value
        Returns:
        the new value
      • complement

        public byte complement()
        Set the value to its complement
        Returns:
        the new value
      • and

        public byte and​(byte b)
        Set value to value & b.
        Returns:
        the new value
      • or

        public byte or​(byte b)
        Set value to value | b.
        Returns:
        the new value
      • xor

        public byte xor​(byte b)
        Set value to value ^ b.
        Returns:
        the new value
      • compareTo

        public int compareTo​(byte other)
      • hashCode

        Overrides:
        hashCode in class Object
