AbstractVVSVertex & operator=(const AbstractVVSVertex &)=delete
The assignment operator is private and must never be called.
This is the main namespace within which all identifiers in ThePEG are declared.

AbstractVVSVertex()
Default constructor.
The VertexBase class is the base class for all helicity amplitude vertices.

static void Init()
The standard Init function used to initialize the interfaces.
