Detailed Description

Base class for common behaviour of generator interfaces.

This class is the base class used to specify the behavior of all event generator interface packages. It inherits the GenBase (and hence AthAlgorithm) interfaces.

The common behavior currently consists of:

Providing access to the ATLAS random number generator service
Creating the McEvent and if necessary the McEventCollection

The following virtual methods should be overloaded in the child class:

StatusCode genInitialize() StatusCode callGenerator() StatusCode genFinalize() StatusCode fillEvt(GeneratorEvent* evt)
