Make a simple clone of this object.
Implements ThePEG::InterfacedBase.
|
protectedvirtual |
Make a clone of this object, possibly modifying the cloned object to make it sane.
Reimplemented from ThePEG::InterfacedBase.
|
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.
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
void Herwig::MPIPDF::persistentInput | ( | PersistentIStream & | is, |
int | version | ||
) |
Function used to read in object persistently.
is | the persistent input stream read from. |
version | the version number of the object when written. |
void Herwig::MPIPDF::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
|
virtual |
The valence density.
Return the pdf for the given cvalence parton inside the given particle for the virtuality partonScale and momentum fraction x. The particle is assumed to have a virtuality particleScale. If not overidden by a sub class this implementation will assume that the difference between a quark and anti-quark distribution is due do valense quarks, but return zero for anything else.
Reimplemented from ThePEG::PDFBase.

virtual |
The density.
Return the pdf for the given parton inside the given particle for the virtuality partonScale and momentum fraction x. The particle is assumed to have a virtuality particleScale. For MPIPDF, only the sea quark densities are included here!
