Class Description

                                                                                  
  TObjectSet  - is a container TDataSet                                           
                  This means this object has an extra pointer to an embedded      
                  TObject.                                                        
  Terminology:    This TObjectSet may be an OWNER of the embeded TObject          
                  If the container is the owner it can delete the embeded object  
                  otherwsie it leaves that object "as is"                         
                                                                                  


TObjectSet(const Char_t *name, TObject *obj, Bool_t makeOwner):TDataSet(name)

TObjectSet(TObject *obj,Bool_t makeOwner) : TDataSet("unknown","TObjectSet")

~TObjectSet()

TObject* AddObject(TObject *obj,Bool_t makeOwner)
 Aliase for SetObject method

void Browse(TBrowser *b)
 Browse this dataset (called by TBrowser).

void Delete(Option_t *opt)

Bool_t DoOwner(Bool_t done)
 Set / Reset the ownerships and returns the previous
 status of the ownerships.

TDataSet* Instance() const
 apply the class default ctor to instantiate a new object of the same kind.
 This is a base method to be overriden by the classes
 derived from TDataSet (to support TDataSetIter::Mkdir for example)

TObject* SetObject(TObject *obj,Bool_t makeOwner)
 - Replace the embedded object with a new supplied
 - Destroy the preivous embedded object if this is its owner
 - Return the previous embedded object if any
