Class Description

BrParameterDbManager()

 CTOR - DO NOT USE - use Instance instead

BrParameterDbManager* Instance()

 Get an isntance of the manager

~BrParameterDbManager()

 DTOR

void SetDbParameterFileName(Char_t* filename)

 Set the parameter file name, usually "DetectorParameters.txt" is
 fine

Bool_t Open(Char_t* filename)

 Open the parameter file

TObject* GetDetectorParameters(const Char_t* classname, const Char_t* detector)

Return a pointer to the concrete class.
This is the only place where specific references to concrete class are
given.  But in order to avoid cyclic dependencies, references are
made indirectly through the TMethodCall interface.  That also makes
this routine much more general.  It should not have to be modified
whenever a new parameter class is added.  The only thing one has to
take care of is that the parameter class inherits from TObject, or
better yet (I think) TNamed.  They must also have a constructor
with 3 arguments that are Char_t *'s, eg
BrDetectorParamsTof::BrDetectorParamsTof(Char_t *name,Char_t *title,Char_t *filename)

BrDbObject* GetDbObject(const Char_t* classname, const Char_t* detector)

  Find a geometry database member with the requested detector and in the
  given class.

void List()

 List the currently registered parameter objects.
