◆ InitializeOffsets()

void TBranchElement::InitializeOffsets ( )
protectedvirtual

Initialize the base class subobjects offsets of our sub-branches and set fOffset if we are a container sub-branch.

Note: The offsets are zero for data members so that when SetAddress recursively sets their address, they will get the same address as their containing class because i/o is based on streamer info offsets from the addresss of the containing class.

Offsets are non-zero for base-class sub-branches that are not the leftmost direct base class. They are laid out in memory sequentially and only the leftmost direct base class has the same address as the derived class. The streamer offsets need to be added to the address of the base class subobject which is not the same as the address of the derived class for the non-leftmost direct base classes.

Detect a collection written using a zero pointer in old versions of root.

Hence there is no easy way to detect the case. In newer versions, a zero is written so that a 'missing' collection appears to be an empty collection.

Definition at line 5502 of file TBranchElement.cxx.

◆ SetAddress()

void TBranchElement::SetAddress ( void addr)
virtual

Point this branch at an object.

For a sub-branch, addr is a pointer to the branch object.

For a top-level branch the meaning of addr is as follows:

If addr is zero, then we allocate a branch object internally and the branch is the owner of the allocated object, not the caller. However the caller may obtain a pointer to the branch object with GetObject(). The pointer is reset to zero (nullptr) when the relevant branch object is destroyed.

Example:

branch->SetAddress(0);
Event* event = branch->GetObject();
... Do some work.

If addr is not zero, but the pointer addr points at is zero, then we allocate a branch object and set the passed pointer to point at the allocated object. The caller owns the allocated object and is responsible for deleting it when it is no longer needed.

Example:

Event* event = 0;
branch->SetAddress(&event);
... Do some work.
delete event;
event = 0;

If addr is not zero and the pointer addr points at is also not zero, then the caller has allocated a branch object and is asking us to use it. The caller owns it and must delete it when it is no longer needed.

Example:

Event* event = new Event();
branch->SetAddress(&event);
... Do some work.
delete event;
event = 0;

These rules affect users of TTree::Branch(), TTree::SetBranchAddress(), and TChain::SetBranchAddress() as well because those routines call this one.

An example of a tree with branches with objects allocated and owned by us:

TFile* f1 = new TFile("myfile_original.root");
TTree* t1 = (TTree*) f->Get("MyTree");
TFile* f2 = new TFile("myfile_copy.root", "recreate");
TTree* t2 = t1->Clone(0);
for (Int_t i = 0; i < 10; ++i) {
t1->GetEntry(i);
t2->Fill();
}
t2->Write()
delete f2;
f2 = 0;
delete f1;
f1 = 0;

An example of a branch with an object allocated by us, but owned by the caller:

TFile* f = new TFile("myfile.root", "recreate");
TTree* t = new TTree("t", "A test tree.")
Event* event = 0;
TBranchElement* br = t->Branch("event.", &event);
for (Int_t i = 0; i < 10; ++i) {
... Fill event with meaningful data in some way.
t->Fill();
}
t->Write();
delete event;
event = 0;
delete f;
f = 0;

Notice that the only difference between this example and the following example is that the event pointer is zero when the branch is created.

An example of a branch with an object allocated and owned by the caller:

TFile* f = new TFile("myfile.root", "recreate");
TTree* t = new TTree("t", "A test tree.")
Event* event = new Event();
TBranchElement* br = t->Branch("event.", &event);
for (Int_t i = 0; i < 10; ++i) {
... Fill event with meaningful data in some way.
t->Fill();
}
t->Write();
delete event;
event = 0;
delete f;
f = 0;

If AutoDelete is on (see TBranch::SetAutoDelete), the top level objet will be deleted and recreate each time an entry is read, whether or not the TTree owns the object.

Int_t  btype 
)
protected

Split class cl into sub-branches of this branch.

Create a sub-branch of this branch for each non-empty, non-abstract base class of cl (unless we are a sub-branch of a TClonesArray or an STL container, in which case we do not create a sub-branch), and for each non-split data member of cl.

Note: We do not create sub-branches for base classes of cl if we are a sub-branch of a TClonesArray or an STL container.

Note: We do not create sub-branches for data members which have a class type and which we are splitting.

Note: The above rules imply that the branch heirarchy increases in depth only for base classes of cl (unless we are inside of a TClonesArray or STL container, in which case the depth does not increase, the base class is elided) and for TClonesArray or STL container data members (which have one additional level of sub-branches). The only other way the depth increases is when the top-level branch has a split class data member, in that case the constructor will create a sub-branch for it. In other words, the interior nodes of the branch tree are all either: base class nodes; split class nodes which are direct sub-branches of top-level nodes (created by TClass::Bronch usually); or TClonesArray or STL container master nodes.

Note: The exception to the above is for the top-level branches, Tree::Bronch creates nodes for everything in that case, except for a TObject base class of a class which has the can ignore tobject streamer flag set.
