Detailed Description

A class for filtering UDP packets that matches UDP length criteria
For deeper understanding of the filter concept please refer to PcapFilter.h

Constructor & Destructor Documentation

pcpp::UdpLengthFilter::UdpLengthFilter	(	uint16_t	legnth,
		FilterOperator	op
	)

inline

A constructor that get the UDP length and operator and creates the filter. For example: "filter all UDP packets with length greater or equal to 500"

Parameters

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

void pcpp::UdpLengthFilter::parseToString ( std::string & result )

virtual

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::UdpLengthFilter::setLength ( uint16_t legnth )

inline

Set legnth value

Parameters

[in] legnth The legnth value that will be used in the filter
