Detailed Description

A class for connecting several filters into one filter with logical "or" between them. For example: if the 2 filters are: "IPv4 address = x.x.x.x" + "TCP port dst = 80", then the new filter will be: "IPv4 address = x.x.x.x _OR_ TCP port dst = 80"
This class follows the composite design pattern
For deeper understanding of the filter concept please refer to PcapFilter.h

◆ OrFilter() [1/2]

pcpp::OrFilter::OrFilter ( )

◆ OrFilter() [2/2]

pcpp::OrFilter::OrFilter ( std::vector< GeneralFilter *> &  filters)

A constructor that gets a list of pointers to filters and creates one filter from all filters with logical "or" between them

[in]filtersThe list of pointers to filters

Member Function Documentation

◆ addFilter()

void pcpp::OrFilter::addFilter ( GeneralFilter filter)

Add filter to the or condition

[in]filterThe filter to add

◆ parseToString()

void pcpp::OrFilter::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
No return value

Implements pcpp::GeneralFilter.
