Detailed Description

A class for connecting several filters into one filter with logical "and" 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 _AND_ TCP port dst = 80"
This class follows the composite design pattern
For deeper understanding of the filter concept please refer to PcapFilter.h

AndFilter() [2/2]

pcpp::AndFilter::AndFilter

(

std::vector< GeneralFilter * > &

filters

)

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

Parameters

[in]

filters

The list of pointers to filters

Member Function Documentation

addFilter()

void pcpp::AndFilter::addFilter ( GeneralFilter *  filter )

inline

Add filter to the and condition

Parameters

[in]

filter

The filter to add

parseToString()

void pcpp::AndFilter::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

Implements pcpp::GeneralFilter.

setFilters()

void pcpp::AndFilter::setFilters

(

std::vector< GeneralFilter * > &

filters

)

Remove the current filters and set new ones

Parameters

[in]

filters

The new filters to set. The previous ones will be removed
