virtual vector<Lorentz5Momentum> Herwig::QTildeShowerKinematics1to2::getBasis | ( | ) | const [virtual] |
Implementation of the virtual function returning a set of basis vectors, specific to the type of evolution.
This function will be used by the ForwardShowerEvolver in order to access and .
Implements Herwig::ShowerKinematics.
QTildeShowerKinematics1to2& Herwig::QTildeShowerKinematics1to2::operator= | ( | const QTildeShowerKinematics1to2 & | ) | [private] |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
