Detailed Description

Base class for event generator filtering modules.

Author
Ian Hinchliffe (initial code, December 2001)
Andy Buckley (updates to AthAlgorithm, etc., Dec 2011)
Andy Buckley (conversion to GenBase and tidying, Nov 2013)

This class is the base class used to specify the behavior of all event generator filtering modules and is meant to capture the common behavior of these modules. GenFilter inherits the GenBase interface and is principally used in Generators/GeneratorFilters.

The following virtual methods should be overloaded in the child class: StatusCode filterInitialize() (optional) StatusCode filterEvent() StatusCode filterFinalize() (optional)

LeptonFilter or ElectronFilter are good templates for learning to implement new filters.

Declare a new Gaudi property.
