Detailed Description

The M-Coder (binary) arithmetic encoder class.

Constructor & Destructor Documentation

Create an encoder with a specified number of contexts that sends output to a given bit stream.

SPL::MEncoder::~MEncoder ( )

Destroy an encoder.

void SPL::MEncoder::clearContexts ( )

Clear the state of all of the contexts.

void SPL::MEncoder::dump ( std::ostream & out ) const

Dump the internal state of the encoder for debugging.

int SPL::MEncoder::encodeBypass ( int binVal )

Encode a symbol in bypass mode (i.e., assuming that both symbols are equiprobable).

int SPL::MEncoder::encodeRegular	(	int	contextId,
		int	binVal
	)

Encode a symbol in the specified context.

The symbol binVal is encoded using context contextId.

std::ostream & SPL::MEncoder::getDebugStream ( )

static

Get the stream used for debugging output.

void SPL::MEncoder::setDebugLevel ( int debugLevel )

static

Set the debug level.

void SPL::MEncoder::setDebugStream ( std::ostream & debugStream )

static

Set the stream for debugging output.

void SPL::MEncoder::setNumContexts ( int numContexts )

Set the number of contexts.

void SPL::MEncoder::start ( )

Start the arithmetic code word.

int SPL::MEncoder::terminate ( )

Terminate the arithmetic code word.
