Hi,
Is it safe to do the following(3rd last line): (I apologise for the long
message.)
Compiler: gcc3.0.3
OS: RedHat 7.2
Architecture: i386
class Fruit
{
}
class Basket
{
public:
add(list<Fruit*>& fruits);
}
class Apple : public Fruit
{
}
class AppleTree
{
public:
list<Apple*>* getApples() { return &myApples; }
private:
list<Apple*> myApples;
}
The above classes cannot be modified.
class AppleBasket : Basket
public:
void doWork(AppleTree* appleTree)
{
list<Apple*>& apples = *appleTree.getApples();
add((list<Fruit*>&)apples); <------ is this line
safe???????
}
}
Any help will be much appreciated.
Thanks & Best Regards,
