class ROOT::Math::VirtualIntegratorOneDim: public 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

   @ingroup  Integration
