Method Detail

getInputStream

public InputStream getInputStream()

decode

public int decode()
           throws IOException

Description copied from interface: DecoderChannel

Decodes a single byte

Specified by:

decode in interface DecoderChannel

Returns:

a byte as int

Throws:

IOException - IO exception

align

public void align()
           throws IOException

Description copied from interface: DecoderChannel

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

Specified by:

align in interface DecoderChannel

Throws:

IOException - IO exception

skip

public void skip(long n)
          throws IOException

Description copied from interface: DecoderChannel

Skips over and discards n bytes of data from this channel.

Specified by:

skip in interface DecoderChannel

Parameters:

n - number of bytes to skip

Throws:

IOException - IO exception

decodeNBitUnsignedInteger

public int decodeNBitUnsignedInteger(int n)
                              throws IOException

Decodes and returns an n-bit unsigned integer using the minimum number of bytes required for n bits.

Specified by:

decodeNBitUnsignedInteger in interface DecoderChannel

Parameters:

n - number of bits

Returns:

nbit value

Throws:

IOException - IO exception

decodeBoolean

public boolean decodeBoolean()
                      throws IOException

Specified by:

decodeBinary in interface DecoderChannel

Returns:

binary data

Throws:

IOException - IO exception
