http://en.wikipedia.org/wiki/Multiple_inheritance#The_diamond_problem The "diamond problem" (sometimes referred to as the "deadly diamond of death"[6]) is an ambiguity that arises when two classes B and C inherit from A, and class D inherits from both B and C. If there is a method...
We also have class D that derives from both B and C by using multiple inheritance. You can see in the figure above that the classes essentially form the shape of a diamond – which is why this problem is called the diamond problem. The problem with having an inheritance hierarchy like ...
Multiple inheritance has always has been a topic, if not a debate. In this library, it is resolved by "flattening" the legacy. Single inheritance works as such : Existing inheritance: A - B - C. When writing class X extends A, we find the inheritance X - A - B - C Flattened inher...

Taking a look at the graphic below helps in explaining the diamond problem. Suppose we have 2 classes B and C that derive from the same class – in our example above it would be class A. We also have class D that derives from both B and C by using multiple inheritance. You can ...
