Public Types | |
using | Object = typename AVarSet::Object |
Type of the object to be analysed. | |
using | Interface |
Mark this class as the basic interface. | |
Public Member Functions | |
MVAFilter (const std::string &defaultTrainingName="", double defaultCut=NAN, const std::string &defaultDBObjectName="") | |
Constructor of the filter. | |
~MVAFilter () | |
Default destructor. | |
void | exposeParameters (ModuleParamList *moduleParamList, const std::string &prefix) override |
Expose the set of parameters of the filter to the module parameter list. | |
void | initialize () override |
Initialize the expert before event processing. | |
void | beginRun () override |
Signal to load new run parameters. | |
Weight | operator() (const Object &obj) override |
Function to object for its signalness. | |
virtual std::vector< float > | operator() (const std::vector< Object * > &objs) override |
Evaluate the MVA method over a vector of objects. | |
virtual Weight | operator() (const Object &obj) |
Function to evaluate the object. | |
Weight | operator() (const Object *obj) |
Function to evaluate the object. | |
virtual std::vector< float > | operator() (const std::vector< Object * > &objs) |

virtual double | predict (const Object &obj) |
