Run-Time Type Information

compiler (RTTI) Facilities included in C++ compilers to

allow the type of an object to be determined at run time.

This facility, found in good C++ compilers and some other

high level languages, adds type information to memory

resident objects (i.e. type name or unique type-id). This

allows the run-time system to determine if an object is of a

specific type, for example, to ensure that a cast of an

object is valid.
