Thread: 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..

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

dont worry got it
