Instead, implicit interfaces and compile-time polymorphism move to the fore. Terms Definition OOP Example: class Widget { public: Widget( ); virtual ~Widget(); virtual std::size_t size() const; virtual void normalize(); void swap(Widget& other); ... }; void doProcessing(Widget& w) {...

polymorphism, on the other hand, refers to runtime polymorphism. Because method call resolution does not occur at build time; rather, it occurs at runtime when actual objects are formed. It is accomplished by method overriding. At runtime, every type of object determines which override met...
Method overloading is one of the way java supports static polymorphism. Here we have two definitions of the same method add() which add method would be called is determined by the parameter list at the compile time. That is the reason this is also known as compile time polymorphism. class...

GotW #7a: Minimizing Compile-Time Dependencies, Part 1 Managing dependencies well is an essential part of writing solid code. C++ supports two powerful methods of abstraction: object-oriented programming and generic programming. Both of these are fundame
Due to exhaustive matching DUs provide an alternative to polymorphism when you want to have a method with guaranteed behaviour-per-type (i.e. adding an abstract method on a base type, and then implementing that method in each type). It's a really powerful tool, ask any f#/Scala dev! :...
