◆ decode()

std::auto_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.

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.

◆ getLastUsedTID()

TID Engine::FastScp11::Decoder::getLastUsedTID ( ) const

Returns the last used template id.

◆ resetDictionary()

void Engine::FastScp11::Decoder::resetDictionary ( )

Resets the fast decoder dictionary.
