Constructor & Destructor Documentation

◆ SomeIpTpLayer() [1/2]

pcpp::SomeIpTpLayer::SomeIpTpLayer	(	uint8_t *	data,
		size_t	dataLen,
		Layer *	prevLayer,
		Packet *	packet
	)

inline

A constructor that creates the layer from an existing packet raw data

Parameters

[in]	data	A pointer to the raw data (will be casted to someiptphdr)
[in]	dataLen	Size of the data in bytes
[in]	prevLayer	A pointer to the previous layer
[in]	packet	A pointer to the Packet instance where layer will be stored in

◆ SomeIpTpLayer() [2/2]

pcpp::SomeIpTpLayer::SomeIpTpLayer	(	uint16_t	serviceID,
		uint16_t	methodID,
		uint16_t	clientID,
		uint16_t	sessionID,
		uint8_t	interfaceVersion,
		MsgType	type,
		uint8_t	returnCode,
		uint32_t	offset,
		bool	moreSegmentsFlag,
		const uint8_t *const	data = `nullptr`,
		size_t	dataLen = `0`
	)

A constructor that creates empty layer and sets values

Parameters

[in]	serviceID	Service ID
[in]	methodID	Method ID
[in]	clientID	Client ID
[in]	sessionID	Session ID
[in]	interfaceVersion	Interface Version
[in]	type	Type of the message
[in]	returnCode	Return Code
[in]	offset	Offset indicating the data offset in increments of 16 bytes
[in]	moreSegmentsFlag	Flag indicating whether more SOME/IP-TP Packets will follow
[in]	data	A pointer to the raw data
[in]	dataLen	Size of the data in bytes

Member Function Documentation

◆ getMoreSegmentsFlag()

bool pcpp::SomeIpTpLayer::getMoreSegmentsFlag ( ) const

Get the More Segments Flag

Returns: true if the More Segments Flag is set, false if it is not set

◆ getOffset()

uint32_t pcpp::SomeIpTpLayer::getOffset ( ) const

Get the Offset. Offset is returned in multiple of 16 bytes.

Returns: The offset value

◆ getSomeIpTpHeader()

someiptphdr* pcpp::SomeIpTpLayer::getSomeIpTpHeader ( ) const

inline

Get a pointer to the basic SOME/IP-TP header. Notice this points directly to the data, so every change will change the actual packet data

Returns: A pointer to the someiptphdr

◆ setMoreSegmentsFlag()

void pcpp::SomeIpTpLayer::setMoreSegmentsFlag ( bool flag )

Set the More Segments Flag

Parameters

[in] flag True if the More Segments Flag shall be set, false for resetting

◆ setOffset()

void pcpp::SomeIpTpLayer::setOffset ( uint32_t offset )

Set the Offset. Already has to be in multiples of 16 bytes. If 32 bytes have already been transmitted, the offset has to be set to 2.

Parameters

[in] offset Offset to set. Already has to be in multiples of 16 bytes.

◆ toString()

std::string pcpp::SomeIpTpLayer::toString ( ) const

overridevirtual

Returns: The string representation of the SOME/IP-TP layer

Reimplemented from pcpp::SomeIpLayer.
