Member Function Documentation

virtual void onBeginMessage ( unsigned messageTemplateId )

pure virtual

Called when a new SBE-encoded message started to decode.

Parameters

messageTemplateId Template identifier of the message.

virtual void onBeginSequence	(	int	tag,
		size_t	itemCount
	)

pure virtual

Called just before first entry of the sequence decoding.

Parameters

tag	Tag of the sequence
itemCount	Number of entries in the sequence.

virtual void onBeginSequenceEntry ( size_t index )

pure virtual

Called just before sequence entry decoding.

Parameters

index Index of the entry.

virtual void onEndMessage ( )

pure virtual

Called when decoder finishes current message decoding.

Note: It is possible to reset caller decoder during this callback.

virtual void onEndSequence ( )

pure virtual

Called immediately after the last sequence entry decoded.

virtual void onEndSequenceEntry ( )

pure virtual

Called after the entry was decoded.

virtual void onValue	(	int	tag,
		char	value
	)

pure virtual

Called when single-char field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		short	value
	)

pure virtual

Called when signed 16-bit integer or signed 8-bit integer field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		unsigned short	value
	)

pure virtual

Called when unsigned 16-bit integer or unsigned 8-bit integer field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		int	value
	)

pure virtual

Called when signed 32-bit integer field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		unsigned	value
	)

pure virtual

Called when unsigned 32-bit integer field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		long long	value
	)

pure virtual

Called when signed 64-bit integer field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		unsigned long long	value
	)

pure virtual

Called when unsigned 64-bit integer field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		long long	mantissa,
		int	exponent
	)

pure virtual

Called when decimal field decoded.

Parameters

tag	FIX tag of the field.
mantissa	Mantissa of the decoded decimal value.
exponent	Exponent of the decoded decimal value (in range of -64..63).

virtual void onValue	(	int	tag,
		const char *	value,
		size_t	valueLength
	)

pure virtual

Called when a string (ASCII or Unicode) or byteVector decoded.

Parameters

tag	FIX tag of the field.
value	Pointer to start of decoded data.
valueLength	Length of decoded data (does not include terminating zero for <string> fields).

virtual void onValue	(	int	tag,
		float	value
	)

pure virtual

Called when float field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.

virtual void onValue	(	int	tag,
		double	value
	)

pure virtual

Called when long float (double) field decoded.

Parameters

tag	FIX tag of the field.
value	Decoded value.
