Syntax
__declspec(hidesbase) declarator
The hidesbase argument is used for compatibility with Delphi. It is used to change the standard C++ overriding semantics so that Delphi code can be ported to C++ with minimum modifications.
Note: You can use the macro
HIDESBASE, defined in sysmac.h, as an alternative for __declspec(hidesbase).
The following code example shows the effect of macro HIDESBASE:
| Method f is overridden. | With HIDESBASE, method f is not overridden.
|
class T1 {
public:
virtual void f()
{
puts("T1::f");
}
};
class T2 : public T1 {
public:
void f()
{
puts("T2::f");
}
};
// ...
T1 *t = new T2();
t->f(); // displays T2::f
|
class T1 {
public:
virtual void f()
{
puts("T1::f");
}
};
class T2 : public T1 {
public:
HIDESBASE void f()
{
puts("T2::f");
}
};
// ...
T1 *t = new T2();
t->f(); // displays T1::f
