Member Function Documentation

encode() [1/2]

void Engine::FastCoder::encode	(	Engine::FIXMessage const *	msg,
		Buffer *	buffer )

Encodes the specified fix message to the fast message.

Parameters

[in]	msg	- pointer to fix message to be encoded.
[out]	buffer	- pointer to buffer that will contain fast message after encoding

Exceptions

-	an std::exception with detailed information if an error occurs.

encode() [2/2]

void Engine::FastCoder::encode	(	Engine::FIXMessage const *	msg,
		System::u32	tid,
		Buffer *	buffer )

Encodes the specified fix message to the fast message using the specified template id.

Parameters

[in]	msg	- pointer to fix message to be encoded.
[in]	tid	- template id
[out]	buffer	- pointer to buffer that will contain fast message after encoding

Exceptions

-	an std::exception with detailed information if an error occurs.

newSkel()

std::unique_ptr< FIXMessage > Engine::FastCoder::newSkel

(

const std::string &

msgType

)

Creates a skeleton of a fix message and returns it.

Parameters

[in]

msgType

- null-terminated std::string. Specifies type of new message.

Returns

instance of FIXMessage class.

operator delete()

void Engine::FastCoder::operator delete

(

void *

obj

)

Overloaded delete operator.

operator=()

FastCoder & Engine::FastCoder::operator= ( const FastCoder & )

protected

parse()

std::unique_ptr< FIXMessage > Engine::FastCoder::parse

(

const std::string &

rawMessage

)

Parses the specified std::string and creates a corresponding FIXMessage instance;.

Parameters

[in]

rawMessage

- null-terminated std::string. Should contain a raw fix message.

Returns

instance of FIXMessage class.

resetDictionary()

void Engine::FastCoder::resetDictionary

(

)

Resets the fast coder dictionary.

tryEncode()

void Engine::FastCoder::tryEncode	(	Engine::FIXMessage const *	msg,
		System::u32	tid )

Checks if the message can be encoded without errors, using the specified template.

Silently returns a control if no errors are detected; otherwise throws an std::exception with detailed information. Usssualy used for debugging purpose only.

Parameters

[in]	msg	- pointer to a fix message to be checked.
[in]	tid	- template id.

Exceptions

an	std::exception with detailed information if any errors detected.
