Method Summary

void	codeBit(boolean bit) Code a bit without taking into account context probabilities in an artihmetic like coder.
void	codeBit(boolean bit, int context) Code a bit taking into account context probabilities in an artihmetic like coder.
void	reset() Reset the context probabilities of the coder, if any.

void	swapOutputByteStream(ByteStream outputByteStream) Swaps the current outputByteStream.
void	terminate() Finishes the outputByteStream, if needed.

Method Detail

codeBit

void codeBit(boolean bit,
             int context)

Code a bit taking into account context probabilities in an artihmetic like coder.

Parameters:

bit - bit to encode

context - context the bit

Throws:

WarningException - when some problem with the manipulation of the ByteStream happens

codeBit

void codeBit(boolean bit)

Code a bit without taking into account context probabilities in an artihmetic like coder.

Parameters:

bit - bit to encode

Throws:

WarningException - when some problem with the manipulation of the ByteStream happens

swapOutputByteStream

void swapOutputByteStream(ByteStream outputByteStream)

Swaps the current outputByteStream. Before to call this function you should terminate the last ByteStream with the function terminate.

Parameters:

outputByteStream - ByteStream where the byte are flushed

terminate

void terminate()
               throws WarningException

Finishes the outputByteStream, if needed.

Throws:

WarningException - when some problem with the manipulation of the ByteStream happens

restart

void restart()

Restart the internal variables of the coder.

reset

void reset()

Reset the context probabilities of the coder, if any.
