<p>each object contains a pointer to the vtable of its class, which is then consulted whenever a polymorphic method is called. This mechanism is an example of:<br/>
* <a href="page.php?w=late_binding">late binding</a>, because virtual function calls are not bound until the time of invocation;<br/>
* <a href="page.php?w=single_dispatch">single dispatch</a> (i.e., single-argument polymorphism), because virtual function calls are bound simply by looking through the vtable provided by the first argument (the <code>this</code> object), so the runtime</p><p>
