Member Function Documentation
| virtual double ThePEG::ACDCSampler::generate | ( | ) | [virtual] |
Generarate a new phase space point and return a weight associated with it.
This weight should preferably be 1.
Implements ThePEG::SamplerBase.
| virtual int ThePEG::ACDCSampler::lastBin | ( | ) | const [virtual] |
ACDCSampler is able to sample several different functions separately.
This function returns the last chosen function.
Reimplemented from ThePEG::SamplerBase.
| void ThePEG::ACDCSampler::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
- Parameters:
-
os the persistent output stream written to.
Reimplemented from ThePEG::SamplerBase.
| void ThePEG::ACDCSampler::persistentInput | ( | PersistentIStream & | is, | |
| int | version | |||
| ) |
Function used to read in object persistently.
- Parameters:
-
is the persistent input stream read from. version the version number of the object when written.
Reimplemented from ThePEG::SamplerBase.
| static void ThePEG::ACDCSampler::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::SamplerBase.
| virtual IBPtr ThePEG::ACDCSampler::clone | ( | ) | const [protected, virtual] |
Make a simple clone of this object.
- Returns:
- a pointer to the new object.
Implements ThePEG::InterfacedBase.
| virtual IBPtr ThePEG::ACDCSampler::fullclone | ( | ) | const [protected, virtual] |
Make a clone of this object, possibly modifying the cloned object to make it sane.
- Returns:
- a pointer to the new object.
Reimplemented from ThePEG::InterfacedBase.
| virtual void ThePEG::ACDCSampler::doinitrun | ( | ) | [protected, virtual] |
Initialize this object.
Called in the run phase just before a run begins.
Reimplemented from ThePEG::InterfacedBase.
| virtual void ThePEG::ACDCSampler::dofinish | ( | ) | [protected, virtual] |
Finalize this object.
Called in the run phase just after a run has ended. Used eg. to write out statistics.
Reimplemented from ThePEG::InterfacedBase.
