How to add a new variable
Each variable is defined inside FlavorTag.cc as a class inheriting from FTAlgo. The name of the variable is defined by providing a string argument to the constructor of the parent class. The variable class should implement the process() method which performs the variable computation. The result should be stored in the member variable _result.
An example implementation is shown below.
| Code Block |
|---|
class FtNvtx : public FTAlgo {class FtNvtx : public FTAlgo {
public:
FtNvtx() : FTAlgo("nvtx") {}
void process() { _result = _jet->getVertices().size(); }
};
