		FilterOperator	op
	)

inline

A constructor that gets the IP ID to filter and the operator and creates the filter out of them

Parameters

[in]	ipID	The IP ID to filter
[in]	op	The operator to use (e.g "equal", "greater than", etc.)

void pcpp::IPv4IDFilter::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::IPv4IDFilter::setIpID ( uint16_t ipID )

inline

Set the IP ID to filter

Parameters

[in] ipID The IP ID to filter
