TClass instances represent classes, structs and namespaces in the ROOT type system.

TClass instances are created starting from different sources of information:

TStreamerInfo instances saved in a ROOT file which is opened. This is called in jargon an emulated TClass.
From TProtoClass instances saved in a ROOT pcm file created by the dictionary generator and the dictionary itself.
From a lookup in the AST built by cling.

If a TClass instance is built through the mechanisms 1. and 2., it does not contain information about methods of the class/struct/namespace it represents. Conversely, if built through 3. or 1., it does not carry the information which is necessary to ROOT to perform I/O of instances of the class/struct it represents. The mechanisms 1., 2. and 3. are not mutually exclusive: it can happen that during the execution of the program, all the three are triggered, modifying the state of the TClass instance.

In order to retrieve a TClass instance from the type system, a query can be executed as follows through the static TClass::GetClass method:

auto myClassTClass_0 = TClass::GetClass("myClass");
auto myClassTClass_1 = TClass::GetClass<myClass>();
auto myClassTClass_2 = TClass::GetClass(myClassTypeInfo);

The name of classes is crucial for ROOT. A careful procedure of name normalization is carried out for each and every class. A normalized name is a valid C++ class name. In order to access the name of a class within the ROOT type system, the method TClass::GetName() can be used.

TClass * 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

TObject

Mother of all ROOT objects.

Definition TObject.h:37

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.

UInt_t TClass::GetCheckSum	(	ECheckSum	code,
		Bool_t &	isvalid
	)		const

Compute and/or return the class check sum.

isvalid is set to false, if the function is unable to calculate the checksum.

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. Original algorithm from Victor Perevovchikov (perev.nosp@m.@bnl.nosp@m..gov).

The valid range of code is determined by ECheckSum.

kNoEnum: data members of type enum are not counted in the checksum
kNoRange: return the checksum of data members and base classes, not including the ranges and array size found in comments.
kWithTypeDef: use the sugared type name in the calculation.

This is needed for backward compatibility.

WARNING: this function must be kept in sync with TStreamerInfo::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.

inline

Definition at line 404 of file TClass.h.

◆ HasDefaultConstructor()

Bool_t TClass::HasDefaultConstructor ( Bool_t testio = kFALSE ) const

Return true if we have access to a constructor usable for I/O.

This is typically the default constructor but can also be a constructor specifically marked for I/O (for example a constructor taking a TRootIOCtor* as an argument). In other words, if this routine returns true, TClass::New is guarantee to succeed. To know if the class described by this TClass has a default constructor (public or not), use

cl->GetProperty() & kClassHasDefaultCtor

kClassHasDefaultCtor

@ kClassHasDefaultCtor

Definition TDictionary.h:140

To know if the class described by this TClass has a public default constructor use:

gInterpreter->ClassInfo_HasDefaultConstructor(aClass->GetClassInfo());

staticprivate

Definition at line 3375 of file TClass.cxx.

◆ IgnoreTObjectStreamer()

void TClass::IgnoreTObjectStreamer ( Bool_t doIgnore = 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).

◆ IsStartingWithTObject()

Bool_t TClass::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.

Concretely this means that the following code is proper for this class:

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().

If quiet is true, do no issue a message via Error on case of problems, just return 0.

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.

◆ SetDirectoryAutoAdd()

void TClass::SetDirectoryAutoAdd ( ROOT::DirAutoAdd_t autoAddFunc )

Install a new wrapper around the directory auto add function.

The function autoAddFunc has the signature void (*)(void *obj, TDirectory dir) and should register 'obj' to the directory if dir is not null and unregister 'obj' from its current directory if dir is null

Definition at line 7002 of file TClass.cxx.

◆ SetGlobalIsA()

void TClass::SetGlobalIsA ( IsAGlobalFunc_t func )

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);

TClass

TClass instances represent classes, structs and namespaces in the ROOT type system.

Definition TClass.h:80

'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

TNamed

The TNamed class is the base class for all named ROOT classes.

Definition TNamed.h:29

TNamed::TNamed

TNamed()

Definition TNamed.h:36

m

auto * m

Definition textangle.C:8

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'.

◆ SetStreamerInfo()

TVirtualStreamerInfo * TClass::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 responsibility to implement a StreamerInfo function (override TObject::StreamerInfo). The user must call IsA()->SetStreamerInfo(info) from this function.
