TClass Class Reference

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.

The name of the class as registered in the TClass object and in the list of class is the "normalized name" and is defined as:

The name of the type as accessible from the global scope to which a 'using namespace std;' has been applied to and with:

• all typedefs disagreed except for Double32_t, Float16_t, Long64_t, ULong64_t and std::string.
• default template parameters removed for STL collections and added for any other class templates instances.
• Fully qualified both for the class name itself and all of its component, except that, at least for moment, all 'std::' are stripped.

Definition at line 345 of file TClass.h.

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 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.

	)		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.

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).

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.

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

For example with:

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'.
