  • Method Details

    • shiftLeft

      public static long shiftLeft(long bits, int count)
      This method performs a bitwise left-shift operation.
      Parameters:
      bits - contains the bits to shift.
      count - is the distance of the shift.
      Returns:
      the bits shifted by the specified distance.

    • shiftRight

      public static long shiftRight(long bits, int count)
      This method performs a bitwise right-shift operation.
      Parameters:
      bits - contains the bits to shift.
      count - is the distance of the shift.
      Returns:
      the bits shifted by the specified distance.

    • shiftRightUnsigned

      public static long shiftRightUnsigned(long bits, int count)
      This method performs a bitwise unsigned-right-shift operation.
      Parameters:
      bits - contains the bits to shift.
      count - is the distance of the shift.
      Returns:
      the bits shifted by the specified distance.

    • set

      public static long set(long bits, int index, boolean value)
      This method sets a single bit.
      Parameters:
      bits - contains the bit to set.
      index - is the index of the bit to set.
      value - the new value of the bit.
      Returns:
      the modified version of bits.

    • get

      public static boolean get(long bits, int index)
      This method gets a single bit.
      Parameters:
      bits - contains the bit to get.
      index - is the index of the bit to get.
      Returns:
      the selected bit.

    • not

      public static long not(long bits)
      This method performs a bitwise negation.
      Parameters:
      bits - are the bits to negate.
      Returns:
      the negated bits.

    • and
