decode()

std::unique_ptr< FIXMessage > Engine::FastScp11::Decoder::decode	(	const char *	fastMessage,
		std::size_t	size,
		std::size_t *	decoded = NULL )

Takes a FAST message from the specified buffer and decodes it to a FIX message.

Parameters

[in]	fastMessage	- pointer to array of char that contains FAST message to be decoded.
[in]	size	- the array size.
[out]	decoded	- amount bytes were decoded.

Returns

instance of FIXMessage class or null if fastMessage contains fast scp messages only.

Exceptions

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

decode_u32()

System::u32 Engine::FastScp11::Decoder::decode_u32	(	const char *	fastMessage,
		std::size_t	size,
		std::size_t *	decoded = NULL )

Decodes unsigned int32 at the beginning of the stream.

Parameters

[in]	fastMessage	- pointer to array of char that contains FAST stream.
[in]	size	- the array size.
[out]	decoded	- amount bytes were decoded.

Returns

decoded unsigned int32.

Exceptions

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