◆ HandleMessage()

void doip_client::channel::udp_channel::DoipUdpChannel::HandleMessage ( uds_transport::UdsMessagePtr message )

Function to Hands over a valid received Uds message to upper layer.

Parameters

[in] message The Uds message ptr (unique_ptr semantics) with the request. Ownership of the UdsMessage is given back to the conversation here

Definition at line 55 of file doip_udp_channel.cpp.

                                                                      {

◆ IndicateMessage()

std::pair< uds_transport::UdsTransportProtocolMgr::IndicationResult, uds_transport::UdsMessagePtr > doip_client::channel::udp_channel::DoipUdpChannel::IndicateMessage	(	uds_transport::UdsMessage::Address	source_addr,
		uds_transport::UdsMessage::Address	target_addr,
		uds_transport::UdsMessage::TargetAddressType	type,
		uds_transport::ChannelID	channel_id,
		std::size_t	size,
		uds_transport::Priority	priority,
		uds_transport::ProtocolKind	protocol_kind,
		core_type::Span< std::uint8_t >	payload_info
	)

Function to indicate a start of reception of message.

This is called to indicate the reception of new message by underlying transport protocol handler

Parameters

[in]	source_addr	The UDS source address of message
[in]	target_addr	The UDS target address of message
[in]	type	The indication whether its is phys/func request
[in]	channel_id	The transport protocol channel on which message start happened
[in]	size	The size in bytes of the UdsMessage starting from SID
[in]	priority	The priority of the given message, used for prioritization of conversations
[in]	protocol_kind	The identifier of protocol kind associated to message
[in]	payload_info	The view onto the first received payload bytes, if any. This view shall be used only within this function call. It is recommended that the TP provides at least the first two bytes of the request message, so the DM can identify a functional TesterPresent

Returns: std::pair< IndicationResult, UdsMessagePtr > The pair of IndicationResult and a pointer to UdsMessage owned/created by DM core and returned to the handler to get filled
