◆ Ident() [1/2]

uint64_t dbc::Message::Ident ( ) const

inline

< Returns the message ID.

◆ Ident() [2/2]

void dbc::Message::Ident ( uint64_t ident )

inline

< Sets the message ID (29-bit)

◆ UpdateData()

bool dbc::Message::UpdateData	(	const std::vector< uint8_t > &	message,
		size_t	offset = `0`,
		size_t	data_index = `0`
	)

Sets the internal last message data buffer. Note that the input offset and destination offset is used if the message requires more than one CAN data message before it is complete.

Parameters

message	Message data.
offset	Offset in the message data buffer (input index).
data_index	Offset in the last message data buffer (dest index).

Returns: Returns true if this was the last byte (complete message).
