RooArgList Class Reference

RooArgList is a container object that can hold multiple RooAbsArg objects.

The container has list semantics which means that:

  • Contained objects are ordered, The iterator follows the object insertion order.
  • Objects can be retrieved by name and index
  • Multiple objects with the same name are allowed

Ownership of contents.

Unowned objects are inserted with the add() method. Owned objects are added with addOwned() or addClone(). A RooArgSet either owns all of it contents, or none, which is determined by the first <add> call. Once an ownership status is selected, inappropriate <add> calls will return error status. Clearing the list via removeAll() resets the ownership status. Arguments supplied in the constructor are always added as unowned elements.
