decodeSingleMessage()

bool decodeSingleMessage	(	int	version,
		int	templateId,
		size_t	rootBlockLength,
		const unsigned char *	buffer,
		size_t	offset,
		size_t	count,
		IDecodeListener *	listener,
		size_t *	numberOfDecodedBytes ) const

Tries to decode the given FAST stream buffer into the corresponding FIX Message.

Parameters

[in]	templateId	The identifier of the SBE template, used to decode the input data.
[in]	version	The version of the SBE schema, used to decode the input data.
[in]	rootBlockLength	The length of the root block. This value should be extracted from the message preamble, or from other source.
[in]	buffer	The FAST stream chunk to be decoded.
[in]	offset	The index in the buffer at which decoding begins.
[in]	count	The number of bytes to analyze during the decoding.
[in]	listener	The listener which receives decoding events.
[out]	numberOfDecodedBytes	The number of bytes that contained the encoded FIX Message.

Warning

The message should point to an existing object. This object is not owned by the Decoder and should be managed by the user.

Exceptions

An	exception if the decoding error is detected.

Returns

'true' if the given bytes could be decoded into a FIX message, otherwise - 'false'.

schemaHeaderType()

std::string schemaHeaderType

(

)

const

The name of the encoding type of the message header, which is the same for all messages in a schema.

schemaId()

unsigned schemaId

(

)

const

The schema identifier.

schemaSemanticVersion()

std::string schemaSemanticVersion

(

)

const

The semantic version of the SBE schema.

schemaVersion()

unsigned schemaVersion

(

)

const

The maximum known version of the SBE schema.
