Hi Brandon,
To replace an object in a file, use the kOverwrite option.
Instead of
obj.Write("name")
do
obj.Write("name",TObject::kOverwrite);

Hi Guys,
Got a little question here...
I have an application where I use a TFile as a sort of file system and store
various objects as 'files' within. One of the requirements of this file system
is that I'm able to perform a destructive overwrite of a 'file' object in the
TFile without wiping out the entire TFile and recreating. One of these 'file'
objects is a class the has a TTree* as a member. I'm able to delete the object
fine, and it dissapears from the TFile when I do so. However, in cases where I
delete the object and then create a new one with the same name (to simulate a
destructive overwrite), the size of the TFile is ~ double what it was before (in
this case it only has a single 'file' object.. so double that object's size).
So, the question is, what am I doing wrong?
Thanks as always!
