      • BitOutputStream

        public BitOutputStream​(Stream out)
        Use an OutputStream to produce a BitWriter. The BitWriter will send its bits to the OutputStream as each byte is filled.
        Parameters:
        out - An Output Stream

    • Method Detail

      • nrBits

        public long nrBits()
        Returns the number of bits that have been written to this bitOutputStream. This may include bits that have not yet been written to the underlying outputStream.

      • pad

        public void pad​(int width)
         throws IOException
        Pad the rest of the block with zeros and flush. pad(8) flushes the last unfinished byte. The underlying OutputStream will be flushed.
        Specified by:
        pad in interface BitWriter
        Parameters:
        width - The size of the block to pad in bits. This will typically be 8, 16, 32, 64, 128, 256, etc.
        Throws:
        IOException

      • write

        public void write​(int bits,
                  int width)
           throws IOException
        Write some bits. Up to 32 bits can be written at a time.
        Specified by:
        write in interface BitWriter
        Parameters:
        bits - The bits to be written.
        width - The number of bits to write. (0..32)
        Throws:
        IOException
