Detailed Description

A specialized AthenaEventLoopMgr that allows multiple passes over an event collection.

The number of passes is controlled by a tool called at the end of each pass over the events that implements the INextPassFilter interface (specified using the NextPassFilter property). At the end of each pass the event selector is rewound and the services listed in the ToBeReinitialized property are reinitialized. Typically MultipleEventLoopMgr will be used for calibration jobs, with the INextPassFilter object looking at the status of the constants in the DetectorStore
