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

Member Function Documentation

◆ getFirstOption()

IPv6Option pcpp::IPv6TLVOptionHeader::getFirstOption ( ) const

Returns: An IPv6Option that wraps the first option data or logical null (IPv6Option::isNull() == true) if no options exist

◆ getNextOption()

IPv6Option pcpp::IPv6TLVOptionHeader::getNextOption ( IPv6Option & option ) const

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

Parameters

[in] option A pointer to an option instance

Returns: An IPv6Option object that wraps the option data. In the following cases logical null (IPv6Option::isNull() == true) is returned: (1) input parameter is out-of-bounds for this extension or (2) the next option doesn't exist or (3) the input option is nullptr

◆ getOption()

IPv6Option pcpp::IPv6TLVOptionHeader::getOption ( uint8_t optionType ) const

Retrieve an option by its type

Parameters

[in] optionType Option type

Returns: An IPv6Option object that wraps the option data. If option isn't found a logical null is returned (IPv6Option::isNull() == true)

◆ getOptionCount()

size_t pcpp::IPv6TLVOptionHeader::getOptionCount ( ) const

Returns: The number of options this IPv6 extension contains
