Hi rooters,
The following are the files, please notice the constructor in node.h (in fact, it is necessary to read node.h, test.C, and the root execution only, others being pasted here for completeness):

#include “TObject.h”

};
#endif
//-----------------node.cxx-------------------
#include “node.h”
ClassImp(node)
//--------------------nodeLinkDef.h--------------
#ifdef CINT
#pragma link C++ class node+;
#endif
