Detailed Description

template<typename IdxT, typename NonOptionalT>
class lvr2::BaseOptionalHandle< IdxT, NonOptionalT >

Base class for optional handles (handles that can be "null" or "None").

This class is semantically equivalent to boost::optional<BaseHandle>. This class uses a special index value to store the "None" value. This saves memory.
