A data set (or event source) returns objects that implement the interface hep.analysis.EventSource
and return instances of hep.analysis.EventData for each event. In a
special case of EventData, hep.analysis.NTupleEventData, the
event data object contains parameters (called fields) for a number of events.
Data sets are used in jobs with analysis routines. Java Analysis Studio allows users to access data stored on a remote server when in a remote job, and to access data on their own machines when in a local job, using a local data interface module. See the tutorial for setting up a job for event analysis.
