Detailed Description

This is the purely sequential simulation kernel, executed once per event. The ISF::SimKernel is configured by providing:

• one particle stack service (ISF::IParticleMgr )
• one truth record service (ISF::ITruthSvc)
• n simulation services for the subdetector geometries ( ISF::ISimulationSvc )

The AthAlgorithm::initialize() framework call triggers:

• retrieval of the given components, and subsequent inialize() calls on them
• translation of the ServiceHandleArray<ISF::ISimulationSvc> into a std::vector<ISF::ISimulationSvc*> for fast access of the geometry service

The AthAlgorithm::execute() framework call triggers the following sequence of calls :

• (1) the stack filling call to the ParticleMgr
• (2) the setupEvent() calls to the provided components
• (3) the loop over the particle stack
• (4) the releaseEvent() calls to the provided components
