Hi,
As I'm a new user of OpenSceneGraph, pardon me for this simple question:
For the following class:
class Foo
{
public:
Foo() {}
virtual ~Foo() {}
private:
osg::ref_ptr<osg::Node> mNode;
};
since mNode is a pointer, is it a must to provide a copy constructor and
assignment operator for deep copy to prevent dangling pointer?
If there is a need to provide the copy constructor and assignment operator, is
it correct as illustrated by the codes below?
Foo(const Foo& other)
{
mNode = other.mNode;
}
Foo& operator=(const Foo& other)
{
if (this == &other)
return *this;
mNode = new osg::Node;
mNode = other.mNode;
return *this;
}
Thanks,
Yip Leng
