RooArgProxy Class Reference

RooArgProxy is the abstract interface for RooAbsArg proxy classes.

A RooArgProxy is the general mechanism to store references to other RooAbsArgs inside a RooAbsArg.

Creating a RooArgProxy adds the proxied object to the proxy owners server list (thus receiving value/shape dirty flags from it) and registers itself with the owning class. The latter allows the owning class to change the proxied pointer when the server it points to gets redirected (e.g. in a copy or clone operation).
