Detailed Description

The RaveVertexFitter class is part of the RaveInterface together with RaveSetup.

To fit a vertex the user adds tracks (different formats are supported). Then calls the fit() function where the name of the fitting method and parameters can be passed as a string. RaveVertexFitter provides the getters to extract the results produced by Rave.

◆ VecSize

typedef std::vector<int>::size_type VecSize
private

I am using std::vector<int>::size_type because it is the official return value of .size() although on normal machines a ::size_type is just an unsigned int anyway.

Because std::vector<int>::size_type is so long it is shortened to VecSize
