pcpp::IPv4TotalLengthFilter::IPv4TotalLengthFilter ( uint16_t  totalLength,
FilterOperator  op 

A constructor that gets the total length to filter and the operator and creates the filter out of them

[in]totalLengthThe total length value to filter
[in]opThe operator to use (e.g "equal", "greater than", etc.)

Member Function Documentation

◆ parseToString()

void pcpp::IPv4TotalLengthFilter::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.

◆ setTotalLength()

void pcpp::IPv4TotalLengthFilter::setTotalLength ( uint16_t  totalLength)

Set the total length value

[in]totalLengthThe total length value to filter
