 Default constructor.  Used for I/O by default.

*-*                =====================

       * address is the address of the first item of a structure.
       * leaflist is the concatenation of all the variable names and types
         separated by a colon character :
         The variable name and the variable type are separated by a slash (/).
         The variable type may be 0,1 or 2 characters. If no type is given,
         the type of the variable is assumed to be the same as the previous
         variable. If the first variable does not have a type, it is assumed
         of type F by default. The list of currently supported types is given below:
            - C : a character string terminated by the 0 character
            - B : an 8 bit signed integer (Char_t)
            - b : an 8 bit unsigned integer (UChar_t)
            - S : a 16 bit signed integer (Short_t)
            - s : a 16 bit unsigned integer (UShort_t)
            - I : a 32 bit signed integer (Int_t)
            - i : a 32 bit unsigned integer (UInt_t)
            - F : a 32 bit floating point (Float_t)
            - D : a 64 bit floating point (Double_t)
            - L : a 64 bit signed integer (Long64_t)
            - l : a 64 bit unsigned integer (ULong64_t)

         By default, a variable will be copied to the buffer with the number of
         bytes specified in the type descriptor character. However, if the type
         consists of 2 characters, the second character is an integer that
         specifies the number of bytes to be used when copying the variable
         to the output buffer. Example:
             X         ; variable X, type Float_t
             Y/I       : variable Y, type Int_t
             Y/I2      ; variable Y, type Int_t converted to a 16 bits integer

   See an example of a Branch definition in the TTree constructor.

   Note that in case the data type is an object, this branch can contain
   only this object.

    Note that this function is invoked by TTree::Branch

       * address is the address of the first item of a structure
         or the address of a pointer to an object (see example).

*

 Initialization routine called from the constructor.  This should NOT be made virtual.

 Destructor.

 Add the basket to this branch.

 Add the start entry of the write basket (not yet create)

 Browser interface.

 Loop on all branch baskets. If the file where branch buffers reside is
 writable, free the disk space associated to the baskets of the branch,
 then call Reset(). If the option contains "all", delete also the baskets
 for the subbranches.
 The branch is reset.
 NOTE that this function must be used with extreme care. Deleting branch baskets
 fragments the file and may introduce inefficiencies when adding new entries
 in the Tree or later on when reading the Tree.

 Loop on all branch baskets. Drop all baskets from memory except readbasket.
 If the option contains "all", drop all baskets including
 read- and write-baskets.

 Increase BasketEntry buffer of a minimum of 10 locations
 and a maximum of 50 per cent of current size.

 Loop on all leaves of this branch to fill Basket buffer.

 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.

 Fill each of the leaf of the branch.

 -- Find the immediate sub-branch with passed name.

 -- Find the leaf corresponding to the name 'searchname'.

 Flush to disk all the baskets of this branch and any of subbranches.
 Return the number of bytes written or -1 in case of write error.

 If we have a write basket in memory and it contains some entries and
 has not yet been written to disk, we write it and delete it from memory.
 Return the number of bytes written;

Return pointer to basket basketnumber in this Branch*-
*-*      ====================================================

Return address of basket in the file*-
*-*      ====================================

 Returns (and, if 0, creates) browsable objects for this branch
 See TVirtualBranchBrowsable::FillListOfBrowsables.

 Return icon name depending on type of branch.

 Read all leaves of entry and return total number of bytes read.

 The input argument "entry" is the entry number in the current tree.
 In case of a TChain, the entry number in the current Tree must be found
 before calling this function. For example:

     TChain* chain = ...;
     Long64_t localEntry = chain->LoadTree(entry);
     branch->GetEntry(localEntry);

 The function returns the number of bytes read from the input buffer.
 If entry does not exist, the function returns 0.
 If an I/O error occurs, the function returns -1.

 See IMPORTANT REMARKS in TTree::GetEntry.

 Read all leaves of an entry and export buffers to real objects in a TClonesArray list.

 Returns total number of bytes read.

 Return pointer to the file where branch buffers reside, returns 0
 in case branch buffers reside in the same file as tree header.
 If mode is 1 the branch buffer file is recreated.

*Return pointer to the 1st Leaf named name in thisBranch
*-*        =======================================================

-*-*-*Return all elements of one row unpacked in internal array fValues
*-*      =================================================================

 Get our top-level parent branch in the tree.

 Find the parent branch of child.
 Return 0 if child is not in this branch hierarchy.

 Return total number of bytes in the branch (including current buffer)

 Return total number of bytes in the branch (excluding current buffer)
 if option ="*" includes all sub-branches of this branch too

 Return total number of zip bytes in the branch
 if option ="*" includes all sub-branches of this branch too

 Return kTRUE if an existing object in a TBranchObject must be deleted.

 Return kTRUE if more than one leaf or browsables, kFALSE otherwise.

 keep a maximum of fMaxEntries in memory

  Baskets associated to this branch are forced to be in memory.
  You can call TTree::SetMaxVirtualSize(maxmemory) to instruct
  the system that the total size of the imported baskets does not
  exceed maxmemory bytes.
  The function returns the number of baskets that have been put in memory.
  This method may be called to force all baskets of one or more branches
  in memory when random access to entries in this branch is required.
  See also TTree::LoadBaskets to load all baskets of all branches in memory.

 Print TBranch parameters

 Loop on all leaves of this branch to read Basket buffer.

 Loop on all leaves of this branch to read Basket buffer.

  refresh this branch using new information in b
  This function is called by TTree::Refresh

 Reset a Branch.

 Existing buffers are deleted.
 Entries, max and min are reset.

 Reset the address of the branch.

 Static function resetting fgCount

 Set address of this branch.

 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 kTRUE, this existing object will be deleted, a new object
 created by the default constructor, then read from disk by the streamer.

 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 the streamer).

 Set the basket size
 The function makes sure that the basket size is greater than fEntryOffsetlen

 -- Set address of this branch directly from a TBuffer to avoid streaming.

 Note: We do not take ownership of the buffer.

*-*-*-*-*-*-*-*Set the branch/subbranches compression level
*-*            ============================================

 Set the number of entries in this branch.

 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. /castor/... or 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).

 level, use TBranch::SetFile(TFile *file).

 Set object this branch is pointing to.

 Stream a class object

 Write the current basket to disk and return the number of bytes
 written to the file.
