Detailed Description

template<class Record, typename Object, class Filler = MVAModuleHelperDefaultFiller<Object>>
class PhysicsTools::MVAModuleHelper< Record, Object, Filler >

Template for automated variable collection and MVA computation in EDM modules.

The class MVAModuleHelper can be embedded in EDM modules. It automatically collects the variables listed in the MVA training description using type traits and passes them on to the computer. The calibration and or trainer is automatically collected from the EventSetup.
