class HDataSource: public TObject

_HADES_CLASS_DESCRIPTION

HDataSource

  This is an abstract base class. Its derived classes provide the data needed
 for the reconstruction, reading them from different sources.

  The main method of this class is getNextEvent() which is responsible of
 reading data from the source (file...) and put them into the event pointed
 by fEventAddr

  The return value is:
      kDsOk --------> no error.
      kDsEndFile ---> file's end.
      kDsEndData ---> data's end.
      kDsError -----> error.

  Another important method is init(). In this method the data source must
 setup all what it needs to run (get pointers to the target categories, and
 if the returned pointer is NULL, create those categories ...).


  Within the whole framework, the data sources (classes inherited from
 HDataSource) are the responsible for reading the event's data before its
 proccessing.
