Field Detail

ostream

protected BitOutputStream ostream

Underlying bit output stream to which bits and bytes are written.

Constructor Detail

BitEncoderChannel

public BitEncoderChannel(OutputStream ostream)

Construct an encoder from output stream.

Parameters:

ostream - output stream

Method Detail

getOutputStream

public OutputStream getOutputStream()

Specified by:

getOutputStream in interface EncoderChannel

getLength

public int getLength()

Description copied from interface: EncoderChannel

Returns the number of bytes written.

Specified by:

getLength in interface EncoderChannel

Returns:

number of bytes

flush

public void flush()
           throws IOException

Flush underlying bit output stream.

Specified by:

flush in interface EncoderChannel

Throws:

IOException

align

public void align()
           throws IOException

Description copied from interface: EncoderChannel

Align to next byte-aligned boundary in the stream if it is not already at such a boundary

Specified by:

align in interface EncoderChannel

Throws:

IOException - IO exception

encode

public void encode(int b)
            throws IOException

Specified by:

encode in interface EncoderChannel

Throws:

IOException

encode

public void encode(byte[] b,
                   int off,
                   int len)
            throws IOException

Specified by:

encode in interface EncoderChannel

Throws:

IOException

encodeNBitUnsignedInteger

public void encodeNBitUnsignedInteger(int b,
                                      int n)
                               throws IOException

Encode n-bit unsigned integer. The n least significant bits of parameter b starting with the most significant, i.e. from left to right.
