TClass instances represent classes, structs and namespaces in the ROOT type system.
TClass instances are created starting from different sources of information:
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:
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.

then on return, one must do:
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.

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.
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.

| 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

| 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:
'cl' is a pointer to the TClass object that corresponds to the 'pointer type' used to retrieve the value 'obj'
For example with:
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'.

| 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.
