ROOT::Math::IBaseFunctionMultiDimTempl< T > Class Template Reference

Description

template<class T>
class ROOT::Math::IBaseFunctionMultiDimTempl< T >

Documentation for the abstract class IBaseFunctionMultiDim. Interface (abstract class) for generic functions objects of multi-dimension Provides a method to evaluate the function given a vector of coordinate values, by implementing operator() (const double *). In addition it defines the interface for copying functions via the pure virtual method Clone() and the interface for getting the function dimension via the NDim() method. Derived classes must implement the pure private virtual method DoEval(const double *) for the function evaluation in addition to NDim() and Clone().

Clone()

template<class T >

virtual IBaseFunctionMultiDimTempl<T>* ROOT::Math::IBaseFunctionMultiDimTempl< T >::Clone ( ) const

pure virtual

Clone a function. Each derived class must implement their version of the Clone method

Implemented in ROOT::Math::WrappedParamFunctionGen< FuncPtr >, ROOT::Math::WrappedParamFunction< FuncPtr >, ROOT::Math::WrappedMemMultiFunction< FuncObj, MemFuncPtr >, ROOT::Math::WrappedMultiFunction< Func >, ROOT::Math::MultiNumGradFunction, ROOT::Math::MinimTransformFunction, ROOT::Math::LSResidualFunc, ROOT::Math::GradFunctor, ROOT::Math::Functor, and ROOT::Fit::FcnAdapter.

DoEval()

template<class T >

virtual T ROOT::Math::IBaseFunctionMultiDimTempl< T >::DoEval ( const T *  x ) const

privatepure virtual

Implementation of the evaluation function. Must be implemented by derived classes

Implemented in ROOT::Math::IParametricGradFunctionMultiDimTempl< T >, and ROOT::Math::IParametricFunctionMultiDimTempl< T >.

NDim()

template<class T >

virtual unsigned int ROOT::Math::IBaseFunctionMultiDimTempl< T >::NDim ( ) const

pure virtual

Retrieve the dimension of the function

Implemented in ROOT::Math::WrappedParamFunctionGen< FuncPtr >, ROOT::Math::WrappedParamFunction< FuncPtr >, ROOT::Math::WrappedMemMultiFunction< FuncObj, MemFuncPtr >, ROOT::Math::WrappedMultiFunction< Func >, ROOT::Math::MultiNumGradFunction, ROOT::Math::MinimTransformFunction, ROOT::Math::LSResidualFunc, ROOT::Math::GradFunctor, ROOT::Math::Functor, and ROOT::Fit::FcnAdapter.

operator()()

template<class T >

T ROOT::Math::IBaseFunctionMultiDimTempl< T >::operator() ( const T *  x ) const

inline

Evaluate the function at a point x[]. Use the pure virtual private method DoEval which must be implemented by the sub-classes

Definition at line 92 of file IFunction.h.

         {
            return DoEval(x);
         }
