fill_vertex_times()

virtual void VertexTimeAlgorithmBase::fill_vertex_times ( std::vector< TransientVertex > &  pvs )

inlinevirtual

replace the vertices in the input vector by new vertices with time coordinates determined by the vertexTime method this implementation does not alter the weights from the previous fit must be overridden to change weights, coordinates, tracklists or to add or remove vertices
