Detailed Description
The PartonBin class is used by the PartonExtractor class to store information about the extraction of a parton from a particle.Several PartonBin objects can be used to specify a whole chain of partons extracted from particles extracted from other particles. A PartonBin without an incoming() PartonBin represents the incoming particle itself and is used to stop recursion.
After the extraction of a parton, the kinematical variables of that extraction is stored in a orresponding PartonBinInfo object.

Member Function Documentation
| int ThePEG::PartonBin::nDim | ( | bool | doscale | ) |
Detemine the number of degrees of freedom needed to generate the phase space of this and parent partons.
If doscale is true this bin is expected to generate the scale in addition to the momentum fraction.
| double ThePEG::PartonBin::fullFn | ( | Energy2 | newScale = -1.0 *GeV2 |
) |
Return the parton density for this and parent particles.
If the argument is positive, this scale should be used.
| void ThePEG::PartonBin::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
- Parameters:
-
os the persistent output stream written to.
| void ThePEG::PartonBin::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.
