Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.
In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Add the basket to this branch.
Warning: if the basket are not 'flushed/copied' in the same order as they were created, this will induce a slow down in the insert (since we'll need to move all the record that are entere 'too early'). Warning we also assume that the current write basket is not present (aka has been removed) or is empty (no entries).

Loop on all leaves of this branch to back fill Basket buffer.
Use this routine instead of TBranch::Fill when filling a branch individually to catch up with the number of entries already in the TTree.
First it calls TBranch::Fill and then if the number of entries of the branch reach one of TTree cluster's boundary, the basket is flushed.
The function returns the number of bytes committed to the memory basket. If a write error occurs, the number of bytes returned is -1. If no data are written, because e.g. the branch is disabled, the number of bytes returned is 0.
To insure that the baskets of each cluster are located close by in the file, when back-filling multiple branches make sure to call BackFill for the same entry for all the branches consecutively
rather than doing all the entries of one branch at a time.

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.
The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();
(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

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 address 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.

This method must be overridden if a class wants to paint itself.
The difference between Paint() and Draw() is that when a object draws itself it is added to the display list of the pad in which it is drawn (and automatically redrawn whenever the pad is redrawn). While paint just draws the object without adding it to the pad display list.

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

See TBranchElement::SetAddress.
If implied is true, we do not over-ride existing address for sub-branches. The offset is the offset of the sub-object within its parent, it is already included in the addr but is still needed to be added the OnfileObject address when/if we need to use that address.

Set the automatic delete bit.
This bit is used by TBranchObject::ReadBasket to decide if an object referenced by a TBranchObject must be deleted or not before reading a new entry.
If autodel is true, this existing object will be deleted, a new object created by the default constructor, then read from disk by the streamer.
If autodel is false, 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 the streamer).

Set file where this branch writes/reads its buffers.
By default the branch buffers reside in the file where the Tree was created. If the file name where the tree was created is an absolute path name or an URL (e.g. root://host/...) and if the fname is not an absolute path name or an URL then the path of the tree file is prepended to fname to make the branch file relative to the tree file. In this case one can move the tree + all branch files to a different location in the file system and still access the branch files. The ROOT file will be connected only when necessary. If called by TBranch::Fill (via TBasket::WriteFile), the file will be created with the option "recreate". If called by TBranch::GetEntry (via TBranch::GetBasket), the file will be opened in read mode. To open a file in "update" mode or with a certain compression level, use TBranch::SetFile(TFile *file).

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 hierarchy 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.

Write this object to the current directory.
The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".
Writing an object to a file involves the following steps:
Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.
If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().
The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.
An object is read from the file into memory via TKey::Read() or via TObject::Read().
The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
