First of all, it is not ltti. Its RTTI

Run-time type information (RTTI) is a mechanism that allows
the type of an object to be determined during program
execution.

There are three main C++ language elements to run-time type
information:

The dynamic_cast operator. Used for conversion of
polymorphic types.

The typeid operator. Used for identifying the exact type of
an object.

The type_info class. Used to hold the type information
returned by the typeid operator.
