class ROOT::Math::VirtualIntegrator


   Abstract class for all numerical integration methods (1D and multi-dim)
   Interface defining the common methods for the
   numerical integrator classes of one and multi dimensions
   The derived class VirtualIntegratorOneDim defines the methods
   for one-dimensional integration.
   The derived class VirtualIntegratorMultiDim defines the method for
   multi-dimensional integration.
   The concrete classes for one dimension (e.g. GSLIntegrator) or
   multi-dimension (e.g. GSLMCIntegrator) can be created using the
   plug-in manager.
   Users should not use directly this class but the concrete classes ROOT::Math::IntegratorOneDim or
   ROOT::Math::IntegratorMultiDim

Function documentation

virtual ~VirtualIntegrator()

 destructor: no operation

{}

void SetRelTolerance(double )

      set the desired relative Error

void SetAbsTolerance(double )

      set the desired absolute Error

double Result() const

      return  the Result of the last Integral calculation

double Error() const

      return the estimate of the absolute Error of the last Integral calculation

int Status() const

      return the Error Status of the last Integral calculation

int NEval() const

      return number of function evaluations in calculating the integral
      (if integrator do not implement this function returns -1)

{ return -1; }
