Classes
class	VertexView
	Type-erased view on a generic vertex class - implementation won't bother with any VertexTraits at the moment, since the only functions where the xAOD::TruthVertex and xAOD::Vertex have any overlap are the x(), y() and z(), and they have the same name, so there is literally no point at the moment. More...
struct	VertexView::VTable

Functions
std::ostream &	operator<< (std::ostream &s, const VertexView &v)
bool	dummyVertex (const VertexView &v)
