RooNameSet Class Reference

RooNameSet is a utility class that stores the names the objects in a RooArget.

This allows to preserve the contents of a RooArgSet in a specific use contents beyond the lifespan of the object in the RooArgSet. A new RooArgSet can be created from a RooNameSet by offering it a list of new RooAbsArg objects.

Member Function Documentation

◆ Clone()

virtual TObject* RooNameSet::Clone ( const char *  newname) const
inlinevirtual

Make a clone of an object using the Streamer facility.

If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.

If the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirectory. This usually means that the object will be appended to the current ROOT directory.
