Detailed Description

A class for filtering TCP packets that matches TCP window-size criteria
For deeper understanding of the filter concept please refer to PcapFilter.h

Constructor & Destructor Documentation

pcpp::TcpWindowSizeFilter::TcpWindowSizeFilter ( uint16_t  windowSize,
FilterOperator  op 
)
inline

A constructor that get the window-size and operator and creates the filter. For example: "filter all TCP packets with window-size less than 1000"

Parameters
[in]windowSizeThe window-size value that will be used in the filter
[in]opThe operator to use (e.g "equal", "greater than", etc.)

Member Function Documentation

void pcpp::TcpWindowSizeFilter::parseToString ( std::string &  result)
virtual

A method that parses the class instance into BPF string format

Parameters
[out]resultAn empty string that the parsing will be written into. If the string isn't empty, its content will be overridden

Implements pcpp::GeneralFilter.

void pcpp::TcpWindowSizeFilter::setWindowSize ( uint16_t  windowSize)
inline

Set window-size value

Parameters
[in]windowSizeThe window-size value that will be used in the filter
