static void ThePEG::Helicity::AbstractVVVTVertex::Init (  )  [static]

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

Reimplemented from ThePEG::Helicity::VertexBase.

Reimplemented in ThePEG::Helicity::VVVTVertex.

AbstractVVVTVertex& ThePEG::Helicity::AbstractVVVTVertex::operator= ( const AbstractVVVTVertex  )  [private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
