virtual |
The main function called by the EventHandler class to perform a step.
Given the current state of an Event, this function performs the event generation step and includes the result in a new Step object int the Event record.
eh | the EventHandler in charge of the Event generation. |
tagged | if not empty these are the only particles which should be considered by the StepHandler. |
hint | a Hint object with possible information from previously performed steps. |
Veto | if the StepHandler requires the current step to be discarded. |
Stop | if the generation of the current Event should be stopped after this call. |
Exception | if something goes wrong. |
Implements ThePEG::StepHandler.
|
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.
|
privatedelete |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.

Function used to read in object persistently.
is | the persistent input stream read from. |
version | the version number of the object when written. |
