[out]	nLength	Length of raw message data

Return values

ERR_NOERROR No Error.

◆ GetSignalID()

virtual tResult adtf::devicetb::sdk::can::axle::ICANCoder::GetSignalID	(	tChannelID	nChannel,
		const char *	strValueID,
		tSignalID *	pSignalID ) const

pure virtual

Returns the value ID of a given CAN signal name for the specified channel

Parameters

[in]	nChannel	CAN Channel number
[in]	strValueID	Name of CAN signal
[in,out]	pSignalID	Pointer to variable which receives the ID

Note: Relevant value id strings for gettings specific signal ids within a CAN message. In these cases the nChannel is negligible:; "ui8Tag" - returns CAN_SIGNALID_HEADER_TAG; "ui8Channel" - returns CAN_SIGNALID_HEADER_CHANNEL; "tmTimeStamp" - returns CAN_SIGNALID_HEADER_HWTIME

Return values

ERR_NOERROR	No Error.
ERR_NOT_FOUND	The given Name is not valid.

◆ GetSignalValue()

virtual tResult adtf::devicetb::sdk::can::axle::ICANCoder::GetSignalValue	(	tSignalID	nSignalID,
		tSignalValue *	pSignalValue ) const

pure virtual

Returns the decoded value of one CAN signal from the data area given by Begin() On return the field tSignalValue::nTypeTag and the corresponding field in the union will be filled with the appropriate value. To get the signal raw value, the field tSignalValue::nTypeTag has to be set to TAG_RAW_VALUE before calling this method.

Parameters

[in]	nSignalID	Value ID
[in,out]	pSignalValue	Pointer to structure which receives the value

Return values

ERR_NOERROR	No Error.
ERR_MEMORY	The buffer area of the data given by Begin() has no valid size for this message.

		const tSignalValue *	pSignalValue )

pure virtual

Sets the value of one CAN signal in the data area given by ICANCoder::Begin To set the raw value directly, the field tSignalValue::nTypeTag has to be set to TAG_RAW_VALUE and the field tSignalValue::n64RawValue to the new raw value.
