Named container for two doubles, two integers two object points and three string pointers that can be passed as generic named arguments to a variety of RooFit end user methods.

To achieved the named syntax, RooCmdArg objects are created using global helper functions defined in RooGlobalFunc.h that create and fill these generic containers

	)

Constructor from payload parameters.

Constructor with full specification of payload: two integers, two doubles, three string poiners, two object pointers and one RooCmdArg pointer.

Note that the first payload parameter has no default value, because otherwise the implicit creation of a RooCmdArg from const char* would be possible. This would cause ambiguity problems in RooFit code. It is not a problem that the first parameter always has to be given, because creating a RooCmdArg with only a name and no payload doesn't make sense anyway.

◆ Clone()

TObject * RooCmdArg::Clone ( const char * newname = nullptr ) const

inlineoverridevirtual

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.
