The upper layer of SpecTcl event recording/playback code
consists of a pair of objects that interface into
SpecTcl's analysis system. Specifically,
CDBProcessor is used
to write run starts stops and scalers to the
database. It is an CEventProcessor
and will be added to the event processing pipeline
CDBSink, on the other hand
is a CEventSink and will be added
to the event sink pipline. By the time the event sink pipline
is executed for an event, the event has been fully decoded and
can be written to the database.
