double Root () const override
 Returns the previously calculated root.
bool SetFunction (const IGenFunction &f, double xlow, double xup) override
 Sets the function for the rest of the algorithms.
virtual bool SetFunction (const ROOT::Math::IGenFunction &, double, double)
 Sets the function for the rest of the algorithms.
virtual bool SetFunction (const ROOT::Math::IGradFunction &, double)
 Sets the function for algorithms using derivatives.
bool SetFunction (GSLFuncPointer f, void *params, double xlow, double xup)
bool Solve (int maxIter=100, double absTol=1E-8, double relTol=1E-10) override
 Find the root.
