Create a new Directory.
A new directory with name,title is created in the current directory The directory header information is immediately saved in the file A new key is added in the parent directory
When this constructor is called from a class directly derived from TDirectory, the third argument classname MUST be specified. In this case, classname must be the name of the derived class.

Destructor.
Definition at line 101 of file TDirectory.cxx.
Reimplemented in TDirectoryFile.
Definition at line 118 of file TDirectory.h.
Sets the flag controlling the automatic add objects like histograms, TGraph2D, etc in memory.
By default (fAddDirectory = kTRUE), these objects are automatically added to the list of objects in memory. Note that in the classes like TH1, TGraph2D supporting this facility, one object can be removed from its support directory by calling object->SetDirectory(0) or object->SetDirectory(dir) to add it to the list of objects in the directory dir.
NOTE that this is a static function. To call it, use:

Clone an object.
This function is called when the directory is not a TDirectoryFile. This version has to load the I/O package, hence via Cling.
If autoadd is true and if the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirector. This usually means that the object will be appended to the current ROOT directory.
Reimplemented in TDirectoryFile.
Definition at line 328 of file TDirectory.cxx.

examples:
The retrieved object should in principle derive from TObject. If not, the function TDirectory::GetObject should be called. However, this function will still work for a non-TObject, providing that the calling application cast the return type to the correct type (which is the actual type of the object).
NOTE:
The method GetObject offer better protection and avoid the need for any cast:
VERY IMPORTANT NOTE:
In case the class of this object derives from TObject but not as a first inheritance, one must use dynamic_cast<>().
then on return, one can do:
then on return, one must do:
Of course, dynamic_cast<> can also be used in the example 1.

Find a directory using apath.
It apath is null or empty, returns "this" directory. Otherwise use apath to find a directory. The absolute path syntax is: file.root:/dir1/dir2
where file.root is the file and /dir1/dir2 the desired subdirectory in the file. Relative syntax is relative to "this" directory. E.g: ../aa
. Returns 0 in case path does not exist. If printError is true, use Error with 'funcname' to issue an error message.

Save object in filename, if filename is 0 or "", a file with "objectname.root" is created.
The name of the key is the object name. If the operation is successful, it returns the number of bytes written to the file otherwise it returns 0. By default a message is printed. Use option "q" to not print the message. If filename contains ".json" extension, JSON representation of the object will be created and saved in the text file. Such file can be used in JavaScript ROOT (https://root.cern.ch/js/) to display object in web browser When creating JSON file, option string may contain compression level from 0 to 3 (default 0)

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. 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.
