Mother of all ROOT objects.
The TObject class provides default behaviour and protocol for all objects in the ROOT system. It provides protocol for object I/O, error handling, sorting, inspection, printing, drawing, etc. Every object which inherits from TObject can be stored in the ROOT collection classes.
TObject's bits can be used as flags, bits 0 - 13 and 24-31 are reserved as global bits while bits 14 - 23 can be used in different class hierarchies (watch out for overlaps).

◆ TObject() [1/2]
TObject constructor.
It sets the two data words of TObject to their initial values. The unique ID is set to 0 and the status word is set depending if the object is created on the stack or allocated on the heap. Depending on the ROOT environment variable "Root.MemStat" (see TEnv) the object is added to the global TObjectTable for bookkeeping.

◆ CheckedHash()
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.

◆ Clone()

Make a clone of an object using the Streamer facility.
If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.
If the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirectory. This usually means that the object will be appended to the current ROOT directory.

Must be overridden if a class wants to be able to compare itself with other objects. Must return -1 if this is smaller than obj, 0 if objects are equal and 1 if this is larger than obj.

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like
Mother of all ROOT objects.

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.
missing call to RecursiveRemove in destructor).
Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Save this object in the file specified by filename.
- if "filename" contains ".root" the object is saved in filename as root binary file.
- if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
- if "filename" contains ".cc" the object is saved in filename as C code independant from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().
otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.
The function is available via the object context menu.

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:
- Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
- The TBuffer object is filled via the class::Streamer function.
- If the file is compressed (default) a second buffer is created to hold the compressed buffer.
- Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
- The buffer is written to the file.
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.
