Operator overloading and inheritence

Hi,

ive been working on a operator = overloading function, and wondered whether it worked when in an inheritence hierarchy.

For example my base class implements the operator =, and the derived classes inherit this?

Do the derived classes inherit this? Does polymorphism allow this operator = class type to be derived at run time?

For example if i have a the following code:

Code:

---

Juxtacrine j = new Juxtacrine(); // derived object from Cell
Morphogen m = new Morphogen(); //derived object from Cell different to Juxtacrine

m = j; // calls Cell& operator =(Cell& c) - base class implementation

---

Now at the moment it doesnt seem to work as each time i call the =operator it makes a copy of type const Cell&.

Am i going down the right path ? or do i need to rethink what im doing?

Thanks in advance..

It doesn't get inherited. You would need to create an assignment operator for your derived class which calls the assignment operator of the base class and then does any special things for the derived class.

ok cool thanks, how do i call the baseclass assignment operator?

dont worry got it
