Detailed Description

When following a TCP connection each packet may contain a piece of the data transferred between the client and the server. This class represents these pieces: each instance of it contains a piece of data, usually extracted from a single packet, as well as information about the connection

Constructor & Destructor Documentation

TcpStreamData() [1/3]

pcpp::TcpStreamData::TcpStreamData

(

)

A c'tor for this class that basically zeros all members

TcpStreamData() [2/3]

pcpp::TcpStreamData::TcpStreamData	(	uint8_t *	tcpData,
		size_t	tcpDataLength,
		ConnectionData	connData
	)

A c'tor for this class that get data from outside and set the internal members. Notice that when this class is destroyed it also frees the TCP data it stores

Parameters

[in]	tcpData	A buffer containing the TCP data piece
[in]	tcpDataLength	The length of the buffer
[in]	connData	TCP connection information for this TCP data

~TcpStreamData()

pcpp::TcpStreamData::~TcpStreamData

(

)

A d'tor for this class

TcpStreamData() [3/3]

pcpp::TcpStreamData::TcpStreamData

(

TcpStreamData &

other

)

A copy c'tor for this class. Notice the data buffer is copied from the source instance to this instance, so even if the source instance is destroyed the data in this instance stays valid. When this instance is destroyed it also frees the data buffer

Parameters

[in]

other

The instance to copy from

Member Function Documentation

getConnectionData()

ConnectionData pcpp::TcpStreamData::getConnectionData ( )

inline

A getter for the connection data

Returns

The connection data

getData()

uint8_t* pcpp::TcpStreamData::getData ( )

inline

A getter for the data buffer

Returns

A pointer to the buffer

getDataLength()

size_t pcpp::TcpStreamData::getDataLength ( )

inline

A getter for buffer length

Returns

Buffer length

operator=()

TcpStreamData& pcpp::TcpStreamData::operator=

(

const TcpStreamData &

other

)

Overload of the assignment operator. Notice the data buffer is copied from the source instance to this instance, so even if the source instance is destroyed the data in this instance stays valid. When this instance is destroyed it also frees the data buffer

Parameters

[in]

other

The instance to copy from

Returns

A reference to this instance
