Member Function Documentation

BuildEvent()

Bool_t TGo4TreeSource::BuildEvent ( TGo4EventElement *  dest )

overridevirtual

Fill the destination event dest from the tree. If end of tree is reached, the current event counter is reset and a kFALSE value is returned.

Reimplemented from TGo4EventSource.
