Run
Time Type Identification (RTTI) uses type
|
|
|
information
stored in objects by the compiler to determine
|
|
|
at
run time the actual type of an object pointed or referred
|
|
|
to.
|
|
|
| • |
RTTI
can only be used when at least one function has
|
|
|
been
declared to be virtual in the class or in a direct or
|
|
|
indirect
base class.
|
|
|
| • |
For
the full benefits of dynamic binding, applications must
|
|
write
code independent of the type of object being pointed
|
|
|
or
referred to.
|
|
|
| • |
RTTI
provides a way for client applications to determine
|
|
|
the
type of an object without having to compromise their
|
|
|
use
of dynamic binding.
