 Default ctor.

 Create a TClass object. This object contains the full dictionary
 of a class. It has list to baseclasses, datamembers and methods.
 Use this ctor to create a standalone TClass object. Most useful
 to get a TClass interface to an interpreted class. Used by TTabCom.
 Normally you would use TClass::GetClass("class") to get access to a
 TClass object for a certain class.

copy constructor

assignement operator

 TClass dtor. Deletes all list that might have been created.

 Read the class.rules files from the default location:.
     $ROOTSYS/etc/class.rules (or ROOTETCDIR/class.rules)

 Read a class.rules file which contains one rule per line with comment
 starting with a #
 Returns the number of rules loaded.
 Returns -1 in case of error.

 Add a schema evolution customization rule.
 The syntax of the rule can be either the short form:
  [type=Read] classname membername [attributes=... ] [version=[...] ] [checksum=[...] ] [oldtype=...] [code={...}]
 or the long form
  [type=Read] sourceClass=classname [targetclass=newClassname] [ source="type membername; [type2 membername2]" ]
      [target="membername3;membername4"] [attributes=... ] [version=...] [checksum=...] [code={...}|functionname]

 For example to set HepMC::GenVertex::m_event to _not_ owned the object it is pointing to:
   HepMC::GenVertex m_event attributes=NotOwner

 Semantic of the tags:
   type : the type of the rule, valid values: Read, ReadRaw, Write, WriteRaw, the default is 'Read'.
   sourceClass : the name of the class as it is on the rule file
   targetClass : the name of the class as it is in the current code ; defaults to the value of sourceClass
   source : the types and names of the data members from the class on file that are needed, the list is separated by semi-colons ';'
   oldtype: in the short form only, indicates the type on disk of the data member.
   target : the names of the data members updated by this rule, the list is separated by semi-colons ';'
   attributes : list of possible qualifiers amongs:
      Owner, NotOwner
   version : list of the version of the class layout that this rule applies to.  The syntax can be [1,4,5] or [2-] or [1-3] or [-3]
   checksum : comma delimited list of the checksums of the class layout that this rule applies to.
   code={...} : code to be executed for the rule or name of the function implementing it.

 Adopt a new set of Data Model Evolution rules.

 Return the set of the schema rules if any.

 Return the set of the schema rules if any.
 If create is true, create an empty set

 Register a TClassRef object which points to this TClass object.
 When this TClass object is deleted, 'ref' will be 'Reset'.

 Browse external object inherited from TObject.
 It passes through inheritance tree and calls TBrowser::Add
 in appropriate cases. Static function.

 Browse objects of of the class described by this TClass object.

 This method is called by a browser to get the class information.

 Build a full list of persistent data members.
 Scans the list of all data members in the class itself and also
 in all base classes. For each persistent data member, inserts a
 TRealData object in the list fRealData.

 If pointer is not 0, uses the object at pointer
 otherwise creates a temporary object of this class.

 Build the list of real data for an emulated class

 Calculate the offset between an object of this class to
 its base class TObject. The pointer can be adjusted by
 that offset to access any virtual method of TObject like
 Streamer() and ShowMembers().

 Call ShowMembers() on the obj of this class type, passing insp and parent.
 isATObject is -1 if unknown, 0 if it is not a TObject, and 1 if it is a TObject.
 The function returns whether it was able to call ShowMembers().

 Do a ShowMembers() traversal of all members and base classes' members
 using the reflection information from the interpreter. Works also for
 ionterpreted objects.

 Return true if the data member of this TClass can be saved separately.

 Create a Clone of this TClass object using a different name but using the same 'dictionary'.
 This effectively creates a hard alias for the class name.

 Copy the argument.

 Draw detailed class inheritance structure.
 If a class B inherits from a class A, the description of B is drawn
 on the right side of the description of A.
 Member functions overridden by B are shown in class A with a blue line
 erasing the corresponding member function

 Dump contents of object on stdout.
 Using the information in the object dictionary
 each data member is interpreted.
 If a data member is a pointer, the pointer value is printed
 'obj' is assume to point to an object of the class describe by this TClass

 The following output is the Dump of a TArrow object:
   fAngle                   0           Arrow opening angle (degrees)
   fArrowSize               0.2         Arrow Size
   fOption.*fData
   fX1                      0.1         X of 1st point
   fY1                      0.15        Y of 1st point
   fX2                      0.67        X of 2nd point
   fY2                      0.83        Y of 2nd point

   fFillColor               19          fill area color
   fFillStyle               1001        fill area style

 Introduce an escape character (@) in front of a special chars.
 You need to use the result immediately before it is being overwritten.

 Return a pointer the the real class of the object.
 This is equivalent to object->IsA() when the class has a ClassDef.
 It is REQUIRED that object is coming from a proper pointer to the
 class represented by 'this'.
 Example: Special case:
    class MyClass : public AnotherClass, public TObject
 then on return, one must do:
    TObject *obj = (TObject*)((void*)myobject)directory->Get("some object of MyClass");
    MyClass::Class()->GetActualClass(obj); // this would be wrong!!!
 Also if the class represented by 'this' and NONE of its parents classes
 have a virtual ptr table, the result will be 'this' and NOT the actual
 class.

 Return pointer to the base class "classname". Returns 0 in case
 "classname" is not a base class. Takes care of multiple inheritance.

 Return pointer to the base class "cl". Returns 0 in case "cl"
 is not a base class. Takes care of multiple inheritance.

 Return data member offset to the base class "cl".
 Returns -1 in case "cl" is not a base class.
 Returns -2 if cl is a base class, but we can't find the offset
 because it's virtual.
 Takes care of multiple inheritance.

 Return data member offset to the base class "cl".
 Returns -1 in case "cl" is not a base class.
 Takes care of multiple inheritance.

 Return pointer to (base) class that contains datamember.

 Return the Streamer Class allowing streaming (if any).

 Get a wrapper/accessor function around this class custom streamer (member function).

 Return the proxy implementing the IsA functionality.

 Static method returning pointer to TClass of the specified class name.
 If load is true an attempt is made to obtain the class by loading
 the appropriate shared library (directed by the rootmap file).
 If silent is 'true', do not warn about missing dictionary for the class.
 (typically used for class that are used only for transient members)
 Returns 0 in case class is not found.

 Return the class' names massaged with TClassEdit::ShortType with kDropStlDefault.

 Return pointer to class with name.

 Return a pointer to the dictionary loading function generated by
 rootcint

 Return a pointer to the dictionary loading function generated by
 rootcint

 Return pointer to datamember object with name "datamember".

 return offset for member name. name can be a data member in
 the class itself, one of its base classes, or one member in
 one of the aggregated classes.

 In case of an emulated class, the list of emulated TRealData is built

 -- Return pointer to TRealData element with name "name".

 Name can be a data member in the class itself,
 one of its base classes, or a member in
 one of the aggregated classes.

 In case of an emulated class, the list of emulated TRealData is built.

 Get the list of shared libraries containing the code for class cls.
 The first library in the list is the one containing the class, the
 others are the libraries the first one depends on. Returns 0
 in case the library is not found.

 Return list containing the TBaseClass(es) of a class.

 Return list containing the TDataMembers of a class.

 Return list containing the TMethods of a class.

 Returns a list of all public methods of this class and its base classes.
 Refers to a subset of the methods in GetListOfMethods() so don't do
 GetListOfAllPublicMethods()->Delete().
 Algorithm used to get the list is:
 - put all methods of the class in the list (also protected and private
   ones).
 - loop over all base classes and add only those methods not already in the
   list (also protected and private ones).
 - once finished, loop over resulting list and remove all private and
   protected methods.

 Returns a list of all public data members of this class and its base
 classes. Refers to a subset of the data members in GetListOfDatamembers()
 so don't do GetListOfAllPublicDataMembers()->Delete().

 Returns list of methods accessible by context menu.

 Return kTRUE if the class has elements.

 Unregister the TClassRef object.

 Inform the other objects to replace this object by the new TClass (newcl)

 Make sure that the current ClassInfo is up to date.

 Resets the menu list to it's standard value.

 The ls function lists the contents of a class on stdout. Ls output
 is typically much less verbose then Dump().
 If options contains 'streamerinfo', run ls on the list of streamerInfos
 and the list of conversion streamerInfos.

 Makes a customizable version of the popup menu list, i.e. makes a list
 of TClassMenuItem objects of methods accessible by context menu.
 The standard (and different) way consists in having just one element
 in this list, corresponding to the whole standard list.
 Once the customizable version is done, one can remove or add elements.

 Register the fact that an object was moved from the memory location
 'arenaFrom' to the memory location 'arenaTo'.

 Return the list of menu items associated with the class.

 Return pointer to method without looking at parameters.
 Does not look in (possible) base classes.

 Return pointer to method without looking at parameters.
 Does look in all base classes.

 Find the best method (if there is one) matching the parameters.
 The params string must contain argument values, like "3189, \"aap\", 1.3".
 The function invokes GetClassMethod to search for a possible method
 in the class itself or in its base classes. Returns 0 in case method
 is not found.

 Find the method with a given prototype. The proto string must be of the
 form: "char*,int,double". Returns 0 in case method is not found.

 Look for a method in this class that has the interface function
 address faddr.

 Look for a method in this class that has the name and
 signature

 Return the number of data members of this class
 Note that in case the list of data members is not yet created, it will be done
 by GetListOfDataMembers().

 Return the number of methods of this class
 Note that in case the list of methods is not yet created, it will be done
 by GetListOfMethods().

 returns a pointer to the TVirtualStreamerInfo object for version
 If the object doest not exist, it is created

 Note: There are two special version numbers:

       0: Use the class version from the currently loaded class library.
      -1: Assume no class library loaded (emulated class).

 Warning:  If we create a new streamer info, whether or not the build
           optimizes is controlled externally to us by a global variable!
           Don't call us unless you have set that variable properly
           with TStreamer::Optimize()!

  When the class kIgnoreTObjectStreamer bit is set, the automatically
  generated Streamer will not call TObject::Streamer.
  This option saves the TObject space overhead on the file.
  However, the information (fBits, fUniqueID) of TObject is lost.

  Note that to be effective for objects streamed object-wise this function
  must be called for the class deriving directly from TObject, eg, assuming
  that BigTrack derives from Track and Track derives from TObject, one must do:
     Track::Class()->IgnoreTObjectStreamer();
  and not:
     BigTrack::Class()->IgnoreTObjectStreamer();
  To be effective for object streamed member-wise or split in a TTree,
  this function must be called for the most derived class (i.e. BigTrack).

 Return kTRUE if this class inherits from a class with name "classname".
 note that the function returns KTRUE in case classname is the class itself

 Return kTRUE if this class inherits from class cl.
 note that the function returns KTRUE in case cl is the class itself

 Cast obj of this class type up to baseclass cl if up is true.
 Cast obj of this class type down from baseclass cl if up is false.
 If this class is not a baseclass of cl return 0, else the pointer
 to the cl part of this (up) or to this (down).

 Return a pointer to a newly allocated object of this class.
 The class must have a default constructor. For meaning of
 defConstructor, see TClass::IsCallingNew().

 The constructor actually called here can be customized by
 using the rootcint pragma:
    #pragma link C++ ioctortype UserClass;
 For example, with this pragma and a class named MyClass,
 this method will called the first of the following 3
 constructors which exists and is public:
    MyClass(UserClass*);
    MyClass(TRootIOCtor*);
    MyClass(); // Or a constructor with all its arguments defaulted.

 When more than one pragma ioctortype is used, the first seen as priority
 For example with:
    #pragma link C++ ioctortype UserClass1;
    #pragma link C++ ioctortype UserClass2;
 We look in the following order:
    MyClass(UserClass1*);
    MyClass(UserClass2*);
    MyClass(TRootIOCtor*);
    MyClass(); // Or a constructor with all its arguments defaulted.

 Return a pointer to a newly allocated object of this class.
 The class must have a default constructor. For meaning of
 defConstructor, see TClass::IsCallingNew().

 Return a pointer to a newly allocated array of objects
 of this class.
 The class must have a default constructor. For meaning of
 defConstructor, see TClass::IsCallingNew().

 Return a pointer to a newly allocated object of this class.
 The class must have a default constructor. For meaning of
 defConstructor, see TClass::IsCallingNew().

 Explicitly call destructor for object.

 Explicitly call operator delete[] for an array.

 Set the splitability of this class:
   -1: Use the default calculation
    0: Disallow splitting
    1: Always allow splitting.

 Private function.  Set the class version for the 'class' represented by
 this TClass object.  See the public interface:
    ROOT::ResetClassVersion
 defined in TClassTable.cxx

 Note on class version numbers:
   If no class number has been specified, TClass::GetVersion will return -1
   The Class Version 0 request the whole object to be transient
   The Class Version 1, unless specified via ClassDef indicates that the
      I/O should use the TClass checksum to distinguish the layout of the class

 Set pointer to current TVirtualStreamerInfo

 Return size of object of this class.

 Load class description from I/O buffer and return class object.

 Store class description on I/O buffer.

 Return true if the shared library of this class is currently in the a
 process's memory.  Return false, after the shared library has been
 unloaded or if this is an 'emulated' class created from a file's StreamerInfo.

 Returns true if this class inherits from TObject and if the start of
 the TObject parts is at the very beginning of the objects.
 Concretly this means that the following code is proper for this class:
     ThisClass *ptr;
     void *void_ptr = (void)ptr;
     TObject *obj = (TObject*)void_ptr;
 This code would be wrong if 'ThisClass' did not inherit 'first' from
 TObject.

 Return kTRUE is the class inherits from TObject.

 Return kTRUE is the class is Foreign (the class does not have a Streamer method).

 Do the initialization that can only be done after the CINT dictionary has
 been fully populated and can not be delayed efficiently.

 Set TObject::fBits and fStreamerType to cache information about the
 class.  The bits are
    kIsTObject : the class inherits from TObject
    kStartWithTObject:  TObject is the left-most class in the inheritance tree
    kIsForeign : the class doe not have a Streamer method
 The value of fStreamerType are
    kTObject : the class inherits from TObject
    kForeign : the class does not have a Streamer method
    kInstrumented: the class does have a Streamer method
    kExternal: the class has a free standing way of streaming itself
    kEmulated: the class is missing its shared library.

 Create the collection proxy object (and the streamer object) from
 using the information in the TCollectionProxyInfo.

 Change (i.e. set) the title of the TNamed.

 This function installs a global IsA function for this class.
 The global IsA function will be used if there is no local IsA function (fIsA)

 A global IsA function has the signature:

    TClass *func( TClass *cl, const void *obj);

 'cl' is a pointer to the  TClass object that corresponds to the
 'pointer type' used to retrieve the value 'obj'

  For example with:
    TNamed * m = new TNamed("example","test");
    TObject* o = m
 and
    the global IsA function would be called with TObject::Class() as
    the first parameter and the exact numerical value in the pointer
    'o'.

  In other word, inside the global IsA function. it is safe to C-style
  cast the value of 'obj' into a pointer to the class described by 'cl'.

 Call this method to indicate that the shared library containing this
 class's code has been removed (unloaded) from the process's memory

 Info is a string describing the names and types of attributes
 written by the class Streamer function.
 If info is an empty string (when called by TObject::StreamerInfo)
 the default Streamer info string is build. This corresponds to
 the case of an automatically generated Streamer.
 In case of user defined Streamer function, it is the user responsability
 to implement a StreamerInfo function (override TObject::StreamerInfo).
 The user must call IsA()->SetStreamerInfo(info) from this function.

 Compute and/or return the class check sum.
 The class ckecksum is used by the automatic schema evolution algorithm
 to uniquely identify a class version.
 The check sum is built from the names/types of base classes and
 data members.
 Algorithm from Victor Perevovchikov (perev@bnl.gov).

 if code==1 data members of type enum are not counted in the checksum
 if code==2 return the checksum of data members and base classes, not including the ranges and array size found in comments.
            This is needed for backward compatibility.

 WARNING: this function must be kept in sync with TClass::GetCheckSum.
 They are both used to handle backward compatibility and should both return the same values.
 TStreamerInfo uses the information in TStreamerElement while TClass uses the information
 from TClass::GetListOfBases and TClass::GetListOfDataMembers.

 Adopt the Reference proxy pointer to indicate that this class
 represents a reference.
 When a new proxy is adopted, the old one is deleted.

 Adopt the TMemberStreamer pointer to by p and use it to Stream non basic
 member name.

 Install a new member streamer (p will be copied).

 Function called by the Streamer functions to deserialize information
 from buffer b into object at p.
 This function assumes that the class version and the byte count information
 have been read.
   version  is the version number of the class
   start    is the starting position in the buffer b
   count    is the number of bytes for this object in the buffer

 Function called by the Streamer functions to deserialize information
 from buffer b into object at p.

 Function called by the Streamer functions to serialize object at p
 to buffer b. The optional argument info may be specified to give an
 alternative StreamerInfo instead of using the default StreamerInfo
 automatically built from the class definition.
 For more information, see class TVirtualStreamerInfo.

There is special streamer for the class

 or if Property() has not yet been called.

 Adopt a TClassStreamer object.  Ownership is transfered to this TClass
 object.

 Install a new wrapper around 'new'.

 Install a new wrapper around 'new []'.

 Install a new wrapper around 'delete'.

 Install a new wrapper around 'delete []'.

 Install a new wrapper around the destructor.

 Install a new wrapper around the directory auto add function..
