A reconstructed sequence of two dimensional hits in one super layer.
Class to compute floating point variables from a segment which can be recorded as a flat TNtuple or s...
void initialize() final
Require the Monte Carlo truth information at initialisation.
bool extract(const CDCSegment2D *segment) override
Generate and assign the contained variables.
void beginEvent() final
Prepare the Monte Carlo truth information at start of the event.
VarSet< TruthSegmentVarNames > Super
Type of the base class.
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.
