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

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

overridevirtual

A method that parses the class instance into BPF string format

Parameters

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

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

inline

Set window-size value

Parameters

[in] windowSize The window-size value that will be used in the filter
