Member Function Documentation

Bool_t TTrbSource::BuildEvent ( TGo4EventElement * dest ) [virtual]

This methods actually fills the target event class which is passed as pointer. Uses the latest event which is referenced by fxEvent or fxBuffer. Does _not_ fetch a new event from source, therefore one source event may be used to fill several TTrbEvent classes. To get a new event call NextEvent() before this method.

Bool_t TTrbSource::CheckEventClass ( TClass * cl ) [virtual]

This method checks if event class is suited for the source

Int_t TTrbSource::Close ( ) [virtual]

Close the file or connection.

Bool_t TTrbSource::NextBuffer ( ) [protected]

read next buffer from file into memory

Each buffer contains one full event: First read event header:

Then read rest of buffer from file

Account padding of events to 8 byte boundaries:

Bool_t TTrbSource::NextEvent ( TGo4MbsEvent * target ) [protected]

Fill next xsys event from buffer location into output structure

We fill complete hadaq event into one mbs subevent, not to lose header information decomposing hades subevents is left to the user analysis processor!
