TClass Class Reference

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

TClass instances are created starting from different sources of information:

1. TStreamerInfo instances saved in a ROOT file which is opened. This is called in jargon an emulated TClass.
2. From TProtoClass instances saved in a ROOT pcm file created by the dictionary generator and the dictionary itself.
3. 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.

AddRule()

Bool_t TClass::AddRule ( const char *  rule )

static

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 among: 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.

Return a pointer to 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.

		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.

requestListLoading = kTRUE

)

Return a list containing the TEnums of a class.

The list returned is safe to use from multiple thread without explicitly taking the ROOT global lock.

In the case the TClass represents a namespace, the returned list will implicit take the ROOT global lock upon any access (see TListOfEnumsWithLock)

In the case the TClass represents a class or struct and requestListLoading is true, the list is immutable (and thus safe to access from multiple thread without taking the global lock at all).

In the case the TClass represents a class or struct and requestListLoading is false, the list is mutable and thus we return a TListOfEnumsWithLock which will implicit take the ROOT global lock upon any access.

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).

New() [1/2]

void * TClass::New	(	ENewType	defConstructor = kClassNew,
		Bool_t	quiet = kFALSE
	)		const

Return a pointer to a newly allocated object of this class.

If quiet is true, do not issue a message via Error in case of problems, just return nullptr.

This method is also used by the I/O subsystem to allocate the right amount of memory for the objects. If a default constructor is not defined for a certain class, some options are available. The simplest is to define the default I/O constructor, for example

class myClass {
public:
   myClass() = delete;
   myClass(TRootIOCtor *) {/* do something *‍/}
// more code...
};

Moreover, the constructor called by TClass::New can be customized by using a rootcling pragma as follows:

#pragma link C++ ioctortype UserClass;

TClass::New will then look for a constructor (for a class MyClass in the following example) in the following order, constructing the object using the first one in the list that exists and is declared public:

MyClass(UserClass*);
MyClass(TRootIOCtor*);
MyClass(); // Or a constructor with all its arguments defaulted.

When more than one pragma ioctortype is specified, the priority order is defined as the definition order; the earliest definitions have higher priority. For example with:

#pragma link C++ ioctortype UserClass1;
#pragma link C++ ioctortype UserClass2;

ROOT looks for constructors with the following order:

MyClass(UserClass1*);
MyClass(UserClass2*);
MyClass(TRootIOCtor*);
MyClass(); // Or a constructor with all its arguments defaulted.

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);

'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'.

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.
