- Brief class description:
- This is the base class controlling the generation of the event after the hard sub-process generation. To its help it has a number of step handler objects, most noticeable the
CascadeHandler, the HadronizationHandler and the DecayHandler. Derived classes may also make use of the LuminosityFunction to specify the incoming beams, the PartonExtractor to administer the extraction of partons from incoming hadrons, and the Cuts to specify cuts on the primary sub-process.

Name: ConsistencyEpsilon
Type: Parameter
- Description:
- The maximum fraction of the total invariant mass of a collision that any of the components of the summed momentum is allowed to change during the generation. Used if
ConsistencyLevel is switched on.
Default value: 1.49012e-08
Minimum value: 0
Maximum value: 1
Name: ConsistencyLevel
Type: Switch
- Description:
- Determines how often the event handler should check for charge and energy-momentum conservation.
Registered options:
- 0(
Never)
- No consistency checks are made.
- 1(
EveryCollision)
- Every collision is checked for consistency.
- 2(
EveryStep)
- Every step is checked for consistency.
- 3(
PrintEveryCollision)
- Every collision is checked for consistency. If an inconsistency is found, the event is printed to the log file.
- 4(
PrintEveryStep)
- Every step is checked for consistency. If an inconsistency is found, the event is printed to the log file.
Default value: 1
Name: WarnIncomplete
Type: Switch
- Description:
- Emit a warning during the initialization that this EventHandler is incomplete. Should only be manipulated if the object is in fact an incomlete EventHandler and you do not want a warning.
Registered options:
- 0(
No)
- This EventHandler is either complete or no warning should be emitted in either case.
- 1(
Yes)
- This is an incomplete EventHandler and warning should be emitted.
