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

Todo:
add some methods: "addFilter", "removeFilter", "clearAllFilter"

Constructor & Destructor Documentation

inline

An empty constructor for this class. Use addFilter() to add filters to the or condition

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

Parameters
[in]filtersThe list of pointers to filters

Member Function Documentation

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

Add filter to the or condition

Parameters
[in]filterThe filter to add
void pcpp::OrFilter::parseToString ( std::string &  result)
virtual

A method that parses the class instance into BPF string format

Parameters
