Iterator over all objects?

Hi,

at some point during a ROOT session I want to selectively store objects
of a certain class to a file (such as all TH1F's or so). I unsuccesfully
tried to ask the gRoot object for all the other objects it knows about.
I can only get the classes, but not a list of all objects. If  I had an
Iterator which gives me all objects, I would open a file, then loop over
all the objects, see if it is of the class I'm interested in, and then
call object->Write().
Any hints?

Thanks,
    Martin
