Description:
 def Get(self, path, rootpy=True, **kwargs):
 """ Return the requested object cast as its corresponding subclass in rootpy if one exists and ``rootpy=True``, otherwise return the unadulterated TObject. """

            raise DoesNotExist

        # Ensure that the file we took the object from is alive at least as
        # long as the object being taken from it.

        # Note, Python does *not* own `thing`, it is ROOT's responsibility to
        # delete it in the C++ sense. (SetOwnership is False). However, ROOT
        # will delete the object when the TFile's destructor is run.
        # Therefore, when `thing` goes out of scope and the file referred to
        # by `this` has no references left, the file is destructed and calls
        # `thing`'s delete.

        # (this is thanks to the fact that weak referents (used by keepalive)
        #  are notified when they are dead).

        keepalive(thing, self)
