Listing 4: Using RRef.
class Foo {
public:
Foo() {}
RRef<Bar> getBar() const {return _bar;}
void reset() {_bar.reset();}
private:
DynObj<Bar> _bar;
};
int main() {
Foo foo;
RRef<const Bar> bar( foo.getBar() );
bar().constMethod(); // ok
foo.reset(); // destroys bar
bar().constMethod(); // assert fails
}
