    • get

      public int get(int which)
      Specified by:
      get in interface PackedBits

    • set

      public void set(int which, int value)

      set in interface PackedBits

    • append

      public void append(byte[] data, int numberOfBits, boolean swapOrder)
      Appends data in the array. Fractions of a byte are allowed

    • append

      public void append(int bits, int numberOfBits, boolean swapOrder)
      Appends bits on to the end of the stack.
      Parameters:
      bits - Storage for bits. Relevant bits start at the front.
      numberOfBits - Number of relevant bits in 'bits'
      swapOrder - If true then the first bit in 'bits' will be the last bit in this array.

    • append

      public void append(PackedBits8 bits, int numberOfBits)
      Appends the bit array onto the end

    • append

      public PackedBits8 append(String text)
      Adds bits encoded as a binary string, i.e. "100010010011"

    • read

      public int read(int location, int length, boolean swapOrder)
      Read bits from the array and store them in an int
      Parameters:
      location - The index of the first bit
      length - Number of bits to real up to 32
      swapOrder - Should the order be swapped?
      Returns:
      The read in data
