[ROOT] branch address problem

Hi,

I have a problem with branch addresses declared in a subroutine. I
define and build a branch in a subroutine :

MainClass::function1()
{
...
object = new SomeClass();
mObjArray->Add(object);
tree->Branch("name","SomeClass",&object);
...
}

where mObjArray is a member of my class MainClass
I fill the tree in another subroutine. The problem is that the pointer
to pointer &object may be lost between the two calls (the one defining
the branch and the one filling it) because they are not in the same
function.

For the time being, that means one has to define a global (or a member
of MainClass), which is seen by the two functions. The problem arises if
this member is a TObjArray or some such. I do not have access to the
internal array of addresses fCont. This is normal in regular use, but in
this case, it would be useful to pass it to the branch object.

Any way out of this ? I mean other than building a SomeClass** standard
array of  pointers and managing it myself, which is not particularly
pleasant ?

Any hints are welcome

Damir
