OneOneOneSplitFn()
The default constructor.
This class provides the concrete implementation of the exact leading-order splitting function for ...
virtual IBPtr fullclone() const
Make a clone of this object, possibly modifying the cloned object to make it sane.
virtual IBPtr clone() const
Make a simple clone of this object.
This is an abstract class which defines the common interface for all splitting functions, for both initial-state and final-state radiation.
