A struct representing a Type-Length-Value (TLV) option. These type of options are used inside Hop-By-Hop and Destinations IPv6 extensions

Member Function Documentation

getDataSize()

size_t pcpp::IPv6TLVOptionHeader::TLVOption::getDataSize ( )

inline

Returns

The size of the option data

getTotalSize()

size_t pcpp::IPv6TLVOptionHeader::TLVOption::getTotalSize ( ) const

inline

Returns

The total size of this option (in bytes)

getValueAs()

template<typename T >

T pcpp::IPv6TLVOptionHeader::TLVOption::getValueAs ( )

inline

A templated method to retrieve the option data as a certain type T. For example, if option data is 4B long (integer) then this method should be used as getValueAs<int>() and it will return the option data as an integer.
Notice this return value is a copy of the data, not a pointer to the actual data

Returns

The option data as type T
