class TClass: public TDictionary


The ROOT global object gROOT contains a list of all defined
classes. This list is build when a reference to a class dictionary
is made. When this happens, the static "class"::Dictionary()
function is called to create a TClass object describing the
class. The Dictionary() function is defined in the ClassDef
macro and stored (at program startup or library load time) together
with the class name in the TClassTable singleton object.
For a description of all dictionary classes see TDictionary.

void RemoveClass(TClass* cl)
 static: Remove a class from the list and map of classes
TClass()
 Default ctor.
TClass(const char* name, Bool_t silent = kFALSE)
 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.
TClass(const char* name, Version_t cversion, const char* dfil = 0, const char* ifil = 0, Int_t dl = 0, Int_t il = 0, Bool_t silent = kFALSE)
 Create a TClass object. This object contains the full dictionary
 of a class. It has list to baseclasses, datamembers and methods.
TClass(const char* name, Version_t cversion, const type_info& info, TVirtualIsAProxy* isa, ShowMembersFunc_t showmember, const char* dfil, const char* ifil, Int_t dl, Int_t il, Bool_t silent = kFALSE)
 Create a TClass object. This object contains the full dictionary
 of a class. It has list to baseclasses, datamembers and methods.
void ForceReload(TClass* oldcl)
 we found at least one equivalent.
 let's force a reload
void Init(const char* name, Version_t cversion, const type_info* info, TVirtualIsAProxy* isa, ShowMembersFunc_t showmember, const char* dfil, const char* ifil, Int_t dl, Int_t il, Bool_t silent)

 of a class. It has list to baseclasses, datamembers and methods.
TClass(const TClass& tc)
copy constructor
TClass& operator=(const TClass& )
assignement operator
~TClass()
 TClass dtor. Deletes all list that might have been created.
Int_t ReadRules()
 Read the class.rules files from the default location:.
     $ROOTSYS/etc/class.rules (or ROOTETCDIR/class.rules)
Int_t ReadRules(const char* filename)
 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.
Bool_t AddRule(const char* rule)
 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.
void AdoptSchemaRules(ROOT::TSchemaRuleSet* rules)
 Adopt a new set of Data Model Evolution rules.
const ROOT::TSchemaRuleSet* GetSchemaRules() const
 Return the set of the schema rules if any.
ROOT::TSchemaRuleSet* GetSchemaRules(Bool_t create = kFALSE)
 Return the set of the schema rules if any.
 If create is true, create an empty set
void AddImplFile(const char* filename, int line)
void AddRef(TClassRef* ref)
 Register a TClassRef object which points to this TClass object.
 When this TClass object is deleted, 'ref' will be 'Reset'.
Int_t AutoBrowse(TObject* obj, TBrowser* browser)
 Browse external object inherited from TObject.
 It passes through inheritance tree and calls TBrowser::Add
 in appropriate cases. Static function.
Int_t Browse(void* obj, TBrowser* b) const
 Browse objects of of the class described by this TClass object.
void Browse(TBrowser* b)
 This method is called by a browser to get the class information.
void BuildRealData(void* pointer = 0, Bool_t isTransient = kFALSE)
 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.
void BuildEmulatedRealData(const char* name, Long_t offset, TClass* cl)
 Build the list of real data for an emulated class
void CalculateStreamerOffset() const
 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().
Bool_t CallShowMembers(void* obj, TMemberInspector& insp, Int_t isATObject = -1) const
 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().
void InterpretedShowMembers(void* obj, TMemberInspector& insp)
 Do a ShowMembers() traversal of all members and base classes' members
 using the reflection information from the interpreter. Works also for
 ionterpreted objects.
Bool_t CanSplit() const
 Return true if the data member of this TClass can be saved separately.
TObject * Clone(const char* newname = "") const
 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.
void CopyCollectionProxy(const TVirtualCollectionProxy& )
 Copy the argument.
void Draw(Option_t* option = "")
 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
void Dump(void* obj) const
 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

   fFillColor               19          fill area color
   fFillStyle               1001        fill area style
char * EscapeChars(const char* text) const
 Introduce an escape character (@) in front of a special chars.
 You need to use the result immediately before it is being overwritten.
TClass * GetActualClass(const void* object) const
 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.

   list (also protected and private ones).
 - once finished, loop over resulting list and remove all private and
   protected methods.

 is typically much less verbose then Dump().
 If options contains 'streamerinfo', run ls on the list of streamerInfos
 and the list of conversion streamerInfos.
void MakeCustomMenuList()
 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.
void Move(void* arenaFrom, void* arenaTo) const

 by GetListOfMethods().
TVirtualStreamerInfo* GetStreamerInfo(Int_t version = 0) const
 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()!

void IgnoreTObjectStreamer(Bool_t ignore = kTRUE)
  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).
Bool_t InheritsFrom(const char* cl) const
 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
Bool_t InheritsFrom(const TClass* cl) const
 Return kTRUE if this class inherits from class cl.
 note that the function returns KTRUE in case cl is the class itself
void * DynamicCast(const TClass* base, void* obj, Bool_t up = kTRUE)

 to the cl part of this (up) or to this (down).
void * New(TClass::ENewType defConstructor = kClassNew) const
 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.

void * New(void* arena, TClass::ENewType defConstructor = kClassNew) const
 Return a pointer to a newly allocated object of this class.

 defConstructor, see TClass::IsCallingNew().
void * NewArray(Long_t nElements, TClass::ENewType defConstructor = kClassNew) const
 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().
void * NewArray(Long_t nElements, void* arena, TClass::ENewType defConstructor = kClassNew) const
 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.
void DeleteArray(void* ary, Bool_t dtorOnly = kFALSE)
 Explicitly call operator delete[] for an array.
void SetCanSplit(Int_t splitmode)
 Set the splitability of this class:
   -1: Use the default calculation
    0: Disallow splitting
    1: Always allow splitting.
void SetClassVersion(Version_t version)
 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
void SetCurrentStreamerInfo(TVirtualStreamerInfo* info)
 Set pointer to current TVirtualStreamerInfo
Int_t Size() const
 Return size of object of this class.

 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.
Bool_t IsStartingWithTObject() const
 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.
Bool_t IsTObject() const
 Return kTRUE is the class inherits from TObject.
Bool_t IsForeign() const
 Return kTRUE is the class is Foreign (the class does not have a Streamer method).
void PostLoadCheck()
 Do the initialization that can only be done after the CINT dictionary has
 been fully populated and can not be delayed efficiently.
Long_t Property() const
 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.
void SetContextMenuTitle(const char* title)
 Change (i.e. set) the title of the TNamed.
void SetGlobalIsA(IsAGlobalFunc_t )
 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'.
void SetUnloaded()
 Call this method to indicate that the shared library containing this
 class's code has been removed (unloaded) from the process's memory
TVirtualStreamerInfo * SetStreamerInfo(Int_t version, const char* info = "")
 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.
UInt_t GetCheckSum(UInt_t code = 0) const
 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.
