Member Function Documentation

const FIXForge::FIX::Message& decode	(	const char *	buffer,
		size_t	bufferSize
	)

Decodes the given FAST 1.1 stream chunk into the corresponding FIX Message.

Parameters:

	buffer	Buffer that contains the FAST stream chunk to be decoded.
	bufferSize	Size of the buffer.

Exceptions:

EngineException

if the message cannot be decoded.

Returns:

the decoded FIX message.

const FIXForge::FIX::Message& decode

(

const std::vector< char > &

chunk

)

Decodes the given FAST 1.1 stream chunk into the corresponding FIX Message.

Parameters:

chunk

The FAST stream chunk to be decoded.

Exceptions:

EngineException

if the message cannot be decoded.

Returns:

the decoded FIX message.

bool decode	(	const char *	buffer,
		size_t	offset,
		size_t	count,
		const FIXForge::FIX::Message **	message,
		size_t *	chunkLengh
	)

static bool decodeUnsignedInteger	(	const char *	buffer,
		size_t	bufferSize,
		unsigned int *	value,
		size_t *	fieldLength
	)			[static]

Decoded the FAST-encoded unsigned integer.

Parameters:

	buffer	Buffer that contains the FAST stream chunk to be decoded.
	bufferSize	Size of the buffer.
	value	Decoded value.
	fieldLength	Number of bytes that contained the encoded value.

Returns:

'true' if the stop bit was found and the value was decoded, otherwise - 'false'.

void reset

(

)

Resets the state of the previous values dictionaries (sets the state of the previous values to undefined).
