- /// \brief Base for resolvable objects
- ///
- /// \note \ref Resolvable is a SolvableType, which provides direct
- /// access to many of the underlying sat::Solvables properties.
- /// Don't add common properties here, but in \ref sat::Solvable
- /// and extend \ref sat::SolvableType.
- ///
- /// In most cases you want to retrieve the common properties directly
- /// from a \ref PoolItem or \ref sat::Solvable. Construction from and
- /// explicit conversion to sat::Solvable are supported. Next goal is
- /// to get rid of the smart pointer hierarchy. A Resolvable is actually
- /// an unsigned and derived classes contain no data, so it makes little
- /// sense to wrap this into ReferenceCounted smart pointer.
- ///
- /// \todo Merge with ResObject
- /// \todo Get rid of refcout/smart_prt bloat, as this type is actually IdBased (i.e. sizeof(unsigned))
