Function Documentation

fromJson()

std::unique_ptr<FIXMessage> V12_API Engine::Mapping::fromJson	(	const std::string &	jsonMsg,
		ParserID	parser,
		Engine::ProtocolIndex	preferredVersion = Engine::NA,
		const ParseSettings &	settings = {}
	)

Parses JSON encoded FIX message to FIXMessage object.

Parameters

jsonMsg	- a string containing JSON encoded FIX message.
parser	- parser ID of the already created parser available in the engine to use when parsing the message.
preferredVersion	- protocol index(FIXVersion for standard protocols) to use as default version with the parser specified. Applicable for FIXT.1.1 messages that don't provide FIXVersion explicitly via 'ApplVerID' and/or 'CstmApplVerID' field(s)
settings	- settings to use when parsing the message.

Returns

smart pointer holding FIXMessage object.

operator &()

static JsonEncoding Engine::Mapping::operator& ( const JsonEncoding  left, const JsonEncoding  right  )

operator|()

static JsonEncoding Engine::Mapping::operator| ( const JsonEncoding  left, const JsonEncoding  right  )

toJson()

std::string V12_API Engine::Mapping::toJson	(	const FIXMessage &	msg,
		const JsonEncoding	encodingOptions = JsonEncoding::Default
	)

Serializes FIXMessage object to JSON using "FIX usign JSON" standard.

Parameters

msg	- FIX message object.
encodingOptions	- encoding options to use.

Returns

string containing JSON encoded FIX message
