ROOT::Math::VirtualIntegratorOneDim Class Referenceabstract

Interface (abstract) class for 1D numerical integration It must be implemented by the concrate Integrator classes like ROOT::Math::GSLIntegrator.

Plug-in's exist in ROOT to be able to instantiate the derived classes via the plug-in manager. Users should not use directly this class but the concrete classes ROOT::Math::IntegratorOneDim.
