Category : Web Design

I'm trying to solve a design puzzle in the most efficient way, but I tend to end thinking that I really need a multiple inheritance here. So, here I am, asking the pros. I'm creating an active-record lib that will perform almost identical actions with different name and value variables. I'm on PHP 5.2.13


Suppose I have these classes:

Multiple inheritance with pointer casting and virtual inheritance
Category : Programming Languages

Please explain why there is a difference between the O/P of the following codes...
1> When virtual inheritance is used for class A and B then B::f is called

In addition, most estates are n

Inheritance confusion involving generics and self-inheritance

I'm a little confused by this interface and class definition. Could someone possibly shed some light?


The interface and a class that inherits from it are defined this way:


public abstract class DNum {
}

...the DIM : DNum<DIM> bit is th
