gtsam::SymbolicConditional Class Reference

Detailed Description

SymbolicConditional is a conditional with keys but no probability data, produced by symbolic elimination of SymbolicFactor.

It is also a SymbolicFactor, and thus derives from it. It derives also from Conditional<This>, which is a generic interface class for conditionals.
