Dynamic
binding can be used with overloaded operators
|
|
|
as
well as conversion functions.
|
|
|
| • |
All
that is necessary is to declare the overloaded operators
|
|
to
be virtual in a direct or indirect base class just like we
|
|
|
do
for regular member functions.
|
|
|
| • |
Functions
and overloaded operators that cannot be
|
|
|
implemented
as members can benefit from dynamic
|
|
|
binding
by invoking a virtual member function that
|
|
|
actually
performs the required operation.
|
|
|
| • |
When
this is done, such functions are called “virtual”
|
|
|
friends
(although this is a misleading term!).
