Detailed Description

A class for filtering TCP or UDP port ranges, meaning match only packets which port is within this range, for example: "src portrange 1000-2000" will match only TCP or UDP traffic which source port is in the range of 1000 - 2000
For deeper understanding of the filter concept please refer to PcapFilter.h

Constructor & Destructor Documentation

◆ PortRangeFilter()

pcpp::PortRangeFilter::PortRangeFilter ( uint16_t  fromPort,
uint16_t  toPort,
Direction  dir 

A constructor that gets the port range the the direction and creates the filter with them

[in]fromPortThe lower end of the port range
[in]toPortThe higher end of the port range
[in]dirThe port range direction to filter (source or destination)

Member Function Documentation

◆ parseToString()

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

A method that parses the class instance into BPF string format

[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.

◆ setFromPort()

void pcpp::PortRangeFilter::setFromPort ( uint16_t  fromPort)

Set the lower end of the port range

[in]fromPortThe lower end of the port range

◆ setToPort()

void pcpp::PortRangeFilter::setToPort ( uint16_t  toPort)

Set the higher end of the port range

[in]toPortThe higher end of the port range
