static const char * str(const TNamed *ptr)
Return C++ string corresponding to given TNamed pointer.
static const TNamed * ptr(const char *stringPtr)
Return a unique TNamed pointer for given C++ string.
std::size_t _renameCounter

virtual ~RooNameReg()
Destructor.
const TNamed * constPtr(const char *stringPtr)
Return a unique TNamed pointer for given C++ string.
static RooNameReg & instance()
Return reference to singleton instance.
static const TNamed * known(const char *stringPtr)
If the name is already known, return its TNamed pointer. Otherwise return 0 (don't register the name)...
const char * constStr(const TNamed *namePtr)
Return C++ string corresponding to given TNamed pointer.
static void incrementRenameCounter()
The renaming counter has to be incremented every time a RooAbsArg is renamed.
static const std::size_t & renameCounter()
renamed in this RooFit process.
The TNamed class is the base class for all named ROOT classes.
