Detailed Description
HandlerGroupBase is the base class for the templated HandlerGroup utility class to manage a group ofStepHandlers.
The derived StepHandler has a main StepHandler (CascadeHandler, MultipleInteractionHandler, HadronizationHandler or DecayHandler) while this bease class has a list of pre-hadlers and a list of post-handlers.
The HandlerGroup class is used in the EventHandler and SubProcessHandler to manage the post-sub-process handler, the cascade, multiple interaction, hadronization and decay handler groups. When an event is generated, after the main sub-process is performed, all handler groups are processed in turn. In each group the pre-hadnlers are run first, followed by the main handler (which may be run several times is more than one Hint has been specified) and finally the post-handlers are run.
When a group is initialised before each run, an auxilliary HandlerGroupBase object may be specified to override the default handlers in this group.

Member Function Documentation
| void ThePEG::HandlerGroupBase::addPreHandler | ( | tStepHdlPtr | sh, | |
| tHintPtr | hint, | |||
| const HandlerGroupBase & | ext | |||
| ) |
Add a step handler, sh to the current list of pre-handlers.
Optionally a hint may be specified. If the main handler has already been executed, the object is reinitialized using ext to override defaults.
| void ThePEG::HandlerGroupBase::addPostHandler | ( | tStepHdlPtr | sh, | |
| tHintPtr | hint, | |||
| const HandlerGroupBase & | ||||
| ) |
Add a step handler, sh, to the current list of post-handlers.
Optionally a hint may be specified. If the main handler has already been executed, the object is reinitialized using ext to override defaults.
| void ThePEG::HandlerGroupBase::addHint | ( | tHintPtr | hint, | |
| const HandlerGroupBase & | ext | |||
| ) |
Add a hint to the currently selected main handler.
If the main handler has already been executed, the object is reinitialized using ext to override defaults.
| virtual void ThePEG::HandlerGroupBase::refillDefaultHandler | ( | tStepHdlPtr | ) | [pure virtual] |
Set the current main handler.
If the null pointer use the default main handler.
Implemented in ThePEG::HandlerGroup< HDLR >, ThePEG::HandlerGroup< ThePEG::CascadeHandler >, ThePEG::HandlerGroup< ThePEG::HadronizationHandler >, ThePEG::HandlerGroup< ThePEG::SubProcessHandler >, ThePEG::HandlerGroup< ThePEG::DecayHandler >, and ThePEG::HandlerGroup< ThePEG::MultipleInteractionHandler >.
| void ThePEG::HandlerGroupBase::refillDefaults | ( | const HandlerGroupBase & | ) |
Fill main, pre- and post- handlers with the default ones.
The default handlers in the argument takes precedence to this.
