Detailed Description

An abstract base class for Hop-By-Hop and Destination IPv6 extensions which their structure contains Type-Length-Value (TLV) options. This class provides access to these options and their data as well as methods to create new options. Notice this class is abstract and cannot be instantiated

Constructor & Destructor Documentation

pcpp::IPv6TLVOptionHeader::IPv6TLVOptionHeader ( const std::vector< TLVOptionBuilder > &  options)
protected

A private c'tor to keep this object from being constructed

Member Function Documentation

TLVOption* pcpp::IPv6TLVOptionHeader::getFirstOption ( )
Returns
A pointer to the first option or NULL if option cannot be found
TLVOption* pcpp::IPv6TLVOptionHeader::getNextOption ( TLVOption option)

Returns a pointer to the option that comes after the option given as the parameter

Parameters
[in]optionA pointer to an option instance
Returns
A pointer to the option that comes next or NULL if: (1) input parameter is out-of-bounds for this extension or (2) if the next option doesn't exist or (3) if input option is NULL
TLVOption* pcpp::IPv6TLVOptionHeader::getOption ( uint8_t  optionType)

Retrieve an option by its type

Parameters
[in]optionTypeOption type
Returns
A pointer to the option data or NULL if option cannot be found
size_t pcpp::IPv6TLVOptionHeader::getOptionCount ( )
Returns
The number of options this IPv6 extension contains
