class RooWorkspace::WSDir: public TDirectoryFile

The RooWorkspace is a persistable container for RooFit projects. A workspace can contain and own variables, p.d.f.s, functions and datasets. All objects that live in the workspace are owned by the workspace. The import() method enforces consistency of objects upon insertion into the workspace (e.g. no duplicate object with the same name are allowed) and makes sure all objects in the workspace are connected to each other. Easy accessor methods like pdf(), var() and data() allow to refer to the contents of the workspace by object name. The entire RooWorkspace can be saved into a ROOT TFile and organises the consistent streaming of its contents without duplication.

If a RooWorkspace contains custom classes, i.e. classes not in the ROOT distribution, portability of workspaces can be enhanced by storing the source code of those classes in the workspace as well. This process is also organized by the workspace through the importClassCode() method.
