        protected:

          TList* fListOfShapes  Pointer to the list of the "extra" shape definitions

## Class Description

     TVolumeView

     TVolumeView class is a special kind of TDataSet with one extra
     pointer to wrap any TObject onto TDataSet object

      BE CAREFUL !!!
      One has to use it carefully no control over that extra object
      is performed. This means: the object m_Obj data-member points to can
      be destroyed with no this kbject notifying.
      There is no tool /protection to check whether m_Obj is till alive.
      It is one's  code responsilitiy

TVolumeView(TVolumeView *viewNode,TVolumePosition *nodePosition) : TObjectSet(viewNode->GetName(),(TObject *)nodePosition),fListOfShapes(0) // ,fListOfAttributes(0)

     This ctor creates a TVolumeView structure from the "marked" nodes
     of the "viewNode" input structure
     It re-calculates all positions according of the new topology
     All new TVolume became UNMARKED though

TVolumeView(TVolumeView *viewNode,TVolumeView *topNode) : TObjectSet(viewNode->GetName(),(TObject *)0),fListOfShapes(0) // ,fListOfAttributes(0)

     This ctor creates a TVolumeView structure containing:

       - viewNode on the top
       - skip ALL node from the original viewNode untill topNode found
       - include all "marked" node below "topNode" if any
         topNode is always included

     It re-calculates all positions according of the new topology

TVolumeView(TVolumeView *viewNode,const Char_t *nodeName1,const Char_t *nodeName2) : TObjectSet(viewNode->GetName(),(TObject *)0),fListOfShapes(0) // ,fListOfAttributes(0)

     This ctor creates a TVolumeView structure containing:

       - viewNode on the top
       - skip ALL node from the original viewNode untill topNodeName found
       - include all "marked" node below "topNodename" if any
         topNodeName is always included

     It re-calculates all positions according of the new topology

TVolumeView(TVolumeView *viewNode,const TVolumeView *node1,const TVolumeView *node2) : TObjectSet(viewNode->GetName(),(TObject *)0),fListOfShapes(0) // ,fListOfAttributes(0)

     This ctor creates a TVolumeView structure containing:

       - viewNode on the top
       - skip ALL node from the original viewNode untill topNodeName found
       - include all "marked" node below "topNodename" if any
         topNodeName is always included

     It re-calculates all positions according of the new topology

TVolumeView(TVolume &pattern,Int_t maxDepLevel, const TVolumePosition *nodePosition,EDataSetPass iopt, TVolumeView *rootVolume) : TObjectSet(pattern.GetName(),(TObject *)nodePosition),fListOfShapes(0)

     Creates TVolumeView (view) with a topology similar with TVolume *pattern

      Parameters:
      -----------
      pattern        - the pattern dataset
      iopt = kStruct - clone only my structural links
             kAll    - clone all links
             kRefs   - clone only refs
             kMarked - clone marked (not implemented yet) only

       All new-created sets become the structural ones anyway.

      cout << "ctor for " << GetName() << " - " << GetTitle() << endl;

TVolumeView(TVolumeView &viewNode): TObjectSet(viewNode.GetName(),(TObject *)viewNode.GetPosition()) ,TAtt3D() ,fListOfShapes(viewNode.GetListOfShapes())

TVolumeView(Double_t *translate, Double_t *rotate, UInt_t positionId, TVolume *topNode, const Char_t *thisNodePath, const Char_t *matrixName, Int_t matrixType) // : fListOfAttributes(0)

     Special ctor to back TVolumeView::SavePrimitive() method

TVolumeView(TVolume *thisNode,TVolumePosition *nodePosition) : TObjectSet(thisNode?thisNode->GetName():"",(TObject *)nodePosition),fListOfShapes(0)
