Class to compute floating point variables from a wire hit cluster which can be recorded as a flat TNt...
void initialize() override
Signal the initialisation of the event processing - requires the Monte Carlo information.
void beginEvent() override
Signal the beginning of a new event - loads the Monte Carlo information.
bool extract(const CDCWireHitCluster *ptrCluster) final
Generate and assign the contained variables.
Class that specifies the names of the variables.
Definition: VarNames.h:21
Generic class that generates some named float values from a given object.
Definition: VarSet.h:36
Abstract base class for different kinds of events.
Vehicle class to transport the variable names.
static const size_t nVars
Number of variables to be generated.
static constexpr char const * getName(int iName)
Getter for the name at the given index.
