Constructor Detail

ByteEncoderChannel

public ByteEncoderChannel(OutputStream os)

Construct a byte aligned encoder from output stream.

Parameters:

os - 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

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,
                          IllegalArgumentException

Encode a single boolean value. A false value is encoded as byte 0 and true value is encode as byte 1.

Specified by:

encodeBoolean in interface EncoderChannel

Parameters:

b - boolean

Throws:

IOException - IO exception

IllegalArgumentException

encodeNBitUnsignedInteger

public void encodeNBitUnsignedInteger(int b,

                               throws IOException

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

Specified by:

encodeNBitUnsignedInteger in interface EncoderChannel

Throws:

IOException
