Option field for an IPv6ExtensionHeader Enables adding options to an IPv6ExtensionHeader.
Implementor's note: Make sure to add the result of OptionField::GetSerializedSize () to your IPv6ExtensionHeader::GetSerializedSize () return value. Call OptionField::Serialize and OptionField::Deserialize at the end of your corresponding IPv6ExtensionHeader methods.
OptionField::OptionField | ( | uint32_t | optionsOffset | ) |
Constructor.
optionsOffset | option offset |
void OptionField::AddOption | ( | Ipv6OptionHeader const & | option | ) |
Serialize the option, prepending pad1 or padn option as necessary.
option | the option header to serialize |
