~TBranchObject()
*-*-*-*-*-*Default destructor for a BranchObject*-*-*-*-*-*-*-*-*-*-*-*

void Browse(TBrowser *b)
Int_t Fill()
*-*-*-*-*-*-*-*Loop on all leaves of this branch to fill Basket buffer*-*-*

*-*-*-*-*-*-*-*Reset a Branch*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-* ====================
Existing buffers are deleted
Entries, max and min are reset
void SetAddress(void *add)
*-*-*-*-*-*-*-*Set address of this branch*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-* ====================
void SetAutoDelete(Bool_t autodel)
*-*-*-*-*-*-*-*Set the AutoDelete bit
*-* ====================
This function can be used to instruct Root in TBranchObject::ReadBasket
to not delete the object referenced by a branchobject before reading a
new entry. By default, the object is deleted.
If autodel is kTRUE, this existing object will be deleted, a new object
created by the default constructor, then object->Streamer called.
If autodel is kFALSE, the existing object is not deleted. Root assumes
that the user is taking care of deleting any internal object or array
This can be done in Streamer itself.
If this branch has sub-branches, the function sets autodel for these
branches as well.
We STRONGLY suggest to activate this option by default when you create
the top level branch. This will make the read phase more efficient
because it minimizes the numbers of new/delete operations.
Once this option has been set and the Tree is written to a file, it is
not necessary to specify the option again when reading, unless you
want to set the opposite mode.
void SetBasketSize(Int_t buffsize)
*-*-*-*-*-*-*-*Reset basket size for all subbranches of this branchobject
*-* ==========================================================
void UpdateAddress()
*-*-*-*-*-*-*-*Update branch addresses if a new object was created*-*-*
*-* ===================================================
