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()

pcpp::TcpStreamData::TcpStreamData ( const uint8_t *  tcpData, size_t  tcpDataLength, size_t  missingBytes, const ConnectionData &  connData, std::chrono::time_point< std::chrono::high_resolution_clock >  timestamp  )

inline

A c'tor for this class that get data from outside and set the internal members

Parameters

[in]	tcpData	A pointer to buffer containing the TCP data piece
[in]	tcpDataLength	The length of the buffer
[in]	missingBytes	The number of missing bytes due to packet loss.
[in]	connData	TCP connection information for this TCP data
[in]	timestamp	when this packet was received

Member Function Documentation

getConnectionData()

const ConnectionData& pcpp::TcpStreamData::getConnectionData ( ) const

inline

A getter for the connection data

Returns

The const reference to connection data

getData()

const uint8_t* pcpp::TcpStreamData::getData ( ) const

inline

A getter for the data buffer

Returns

A pointer to the buffer

getDataLength()

size_t pcpp::TcpStreamData::getDataLength ( ) const

inline

A getter for buffer length

Returns

Buffer length

getMissingByteCount()

size_t pcpp::TcpStreamData::getMissingByteCount ( ) const

inline

A getter for missing byte count due to packet loss.

Returns

Missing byte count

getTimeStamp()

timeval pcpp::TcpStreamData::getTimeStamp

(

)

const

Returns

A microsecond precision of the packet timestamp

getTimeStampPrecise()

std::chrono::time_point<std::chrono::high_resolution_clock> pcpp::TcpStreamData::getTimeStampPrecise ( ) const

inline

Returns

A nanosecond precision of the packet timestamp

isBytesMissing()

bool pcpp::TcpStreamData::isBytesMissing ( ) const

inline

Determine if bytes are missing. getMissingByteCount can be called to determine the number of missing bytes.

Returns

true if bytes are missing.
