static void ThePEG::Helicity::AbstractSSSVertex::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::SSSSVertex, and ThePEG::Helicity::SSSVertex.
AbstractSSSVertex& ThePEG::Helicity::AbstractSSSVertex::operator= | ( | const AbstractSSSVertex & | ) | [private] |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
AbstractNoPIOClassDescription<AbstractSSSVertex> ThePEG::Helicity::AbstractSSSVertex::initAbstractSSSVertex [static, private] |
The static object used to initialize the description of this class.
Indicates that this is an abstract class without persistent data.
