A RooTemplateProxy is used to hold references to other RooFit objects in an expression tree. A RooGaussian(..., x, mean, sigma)
can e.g. store references to x, mean, sigma
as
Now, the values of these three can be accessed, and the template argument ensures that only objects that evaluate to real numbers (RooAbsReal) can be stored in such a proxy. These can e.g. be variables, PDFs and functions. To store an object that's a RooCategory
, one would, for example, use
Since ROOT 6.22, the proxy can be used like a pointer to an instance of the template argument. For this, it provides operator*
and operator->
, e.g.
RooTemplateProxy's base class RooArgProxy registers the proxied objects as "servers" of the object that holds the proxy. When the value of the proxied object is changed, the owner is notified, and can recalculate its own value. Renaming or exchanging objects that serve values to the owner of the proxy is handled automatically.
In ROOT 6.22, the classes RooRealProxy and RooCategoryProxy were replaced by RooTemplateProxy<class T>.
Two typedefs have been defined for backward compatibility:
RooRealProxy = RooTemplateProxy<RooAbsReal>
. Any generic object that converts to a real value.RooCategoryProxy = RooTemplateProxy<RooAbsCategory>
. Any category object.To modernise a class, one can change the template argument of the proxy to the most appropriate type, and increment the class version of the owner.

Other template arguments are possible, as long as they derive from RooAbsArg.proxy->
and *proxy
to work with the stored object. No need to cast.Only if necessary If errors about missing symbols connected to RooTemplateProxy appear at link time, a specific template instantiation for RooTemplateProxy is not yet in ROOT's dictionaries. These two lines should be added to the LinkDef.h of the project:
Replace RooMultiCategory
by the proper type. If the proxy was holding a real-valued object, use sourceClass="RooRealProxy"
.
The first line adds the proxy class to the dictionary, the second line enables reading a legacy RooCategoryProxy
from a file, and converting it to the new type-safe proxy. If no old proxies have to be read from files, this line can be omitted.
If the template instantiation that triggered the missing symbols seems to be a very common instantiation, request for it to be added to RooFit by creating a pull request for ROOT. If it is rather uncommon, it is sufficient to add it to the LinkDef.h of the local project only.

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.
