Detailed Description

template<typename T>
class ns3::OptFieldWithPresenceInd< T >

OptFieldWithPresenceInd is a class modeling an optional field (in an Information Element, a management frame, etc.) having an associated Presence Indicator bit.

This class is a wrapper around std::optional (most of its functions are exposed, more can be added if needed) that additionally sets the Presence Indicator flag appropriately when operations like reset or assignment of a value are performed on the optional field.
