Object Splicing

[Anunay]

Hello all,

Can you explain me the basic concept of "OBJECT SPLICING" ? When does
it occur?

Thanks,
Anunay

splicing or slicing?
When does it occur?

If you are talking about slicing:

struct A
{
int first;
};

struct B : public A
{
int second;
};

int main()
{
B b;
A a = b;

// 'b' was sliced: its B part (b.second) was not
// copied into 'a' (because it doesn't exist)
}

If you are really talking about "object splicing", then I don't know
what that is.

It's not a C++ term or concept.

So it's off-topic in [comp.lang.c++].

I've set follow ups to [comp.programming].

I think you've misunderstood a reference to "object
slicing". This results from converting a derived object
to a base object -- everything that's not present in the
base object gets sliced off, leaving only a base object.

The universe is a figment of its own imagination.

Thanks all. I, by mistake, typed "splicing" at both places.

Assuming that the OP meant "object slicing", isn't that a C++ topic?

Err, C++ concept, not topic.
