Detailed Description

Represents an IEEE 802.3 Ethernet protocol layer

Constructor & Destructor Documentation

EthDot3Layer() [1/2]

pcpp::EthDot3Layer::EthDot3Layer ( uint8_t *  data, size_t  dataLen, 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 ether_dot3_header)
[in]	dataLen	Size of the data in bytes
[in]	packet	A pointer to the Packet instance where layer will be stored in

EthDot3Layer() [2/2]

pcpp::EthDot3Layer::EthDot3Layer	(	const MacAddress &	sourceMac,
		const MacAddress &	destMac,
		uint16_t	length
	)

A constructor that creates a new IEEE 802.3 Ethernet header and allocates the data

Parameters

[in]	sourceMac	The source MAC address
[in]	destMac	The destination MAC address
[in]	length	The frame length

Member Function Documentation

computeCalculateFields()

void pcpp::EthDot3Layer::computeCalculateFields ( )

inlinevirtual

Does nothing for this layer

Implements pcpp::Layer.

getDestMac()

MacAddress pcpp::EthDot3Layer::getDestMac ( ) const

inline

Get the destination MAC address

Returns

The destination MAC address

getEthHeader()

ether_dot3_header* pcpp::EthDot3Layer::getEthHeader ( ) const

inline

Get a pointer to the Ethernet header. Notice this points directly to the data, so every change will change the actual packet data

Returns

A pointer to the ether_header

getHeaderLen()

size_t pcpp::EthDot3Layer::getHeaderLen ( ) const

inlinevirtual

Returns

Size of ether_dot3_header

Implements pcpp::Layer.

getOsiModelLayer()

OsiModelLayer pcpp::EthDot3Layer::getOsiModelLayer ( ) const

inlinevirtual

Returns

The OSI Model layer this protocol belongs to

Implements pcpp::Layer.

getSourceMac()

MacAddress pcpp::EthDot3Layer::getSourceMac ( ) const

inline

Get the source MAC address

Returns

The source MAC address

parseNextLayer()

void pcpp::EthDot3Layer::parseNextLayer ( )

virtual

Currently doesn't identify any particular layer (because LLC is not supported yet) so the payload will always be of type PayloadLayer.

Implements pcpp::Layer.

setDestMac()

void pcpp::EthDot3Layer::setDestMac ( const MacAddress &  destMac )

inline

Set destination MAC address

Parameters

destMac

Destination MAC to set

setSourceMac()

void pcpp::EthDot3Layer::setSourceMac ( const MacAddress &  sourceMac )

inline

Set source MAC address

Parameters

sourceMac

Source MAC to set

toString()

std::string pcpp::EthDot3Layer::toString ( ) const

virtual

Returns

A string representation of the layer most important data (should look like the layer description in Wireshark)

Implements pcpp::Layer.
