OO programming is often presented primarily as a technique for controlling the complexity of mutable state. However, many of the concerns of OO programming are orthogonal to this. For example, programming constructs such as object interface types, inheritance, and higher-level design patterns such as publish/subscribe stem from the OO tradition, whereas techniques such as functions, type abstraction, and aggregate operations such as map and fold stem from the functional programming tradition. Many OO techniques have no fundamental relationship to object mutation and identity; for example, interfaces and inheritance can be used very effectively with immutable objects. Much of the expressivity of F# lies in the way it brings the techniques of OO programming and functional programming comfortably together.

You have no doubt heard stories about how the term computer bug was coined, and I d like to tell my favorite one. I have the pleasure of working near the location where Admiral Grace Hopper discovered the first computer bug. Legend has it that Rear Admiral Hopper was working with a large computational computer called a Mark II Aiken Relay Calculator in 1945. To call it a large computer today would be a stretch, but it was the size of a semi back then. When a troublesome electronic problem was traced to a failed relay that had a moth trapped in it, Admiral Hopper noted that the source of the error was a bug and that the system had been debugged and was now operational. To this day we refer to the removal of defective code as debugging.

So far in this chapter, you ve seen only how to define concrete object types. One of the key advances in both functional and OO programming has been the move toward using abstract types for large portions of modern software. These values are typically accessed via interfaces, and you now look at defining new object interface types. Many .NET object interface types begin with the letter I, as in System.IDisposable. The notion of an object interface type can sound a little daunting at first, but the concept is actually simple; object interface types are ones whose member implementations can vary from value to value. As it happens, you ve already met one important family of types whose implementations also vary from value to value: F# function types! In 3, you saw how functions can be used to model a range of concepts such as comparison functions, aggregation functions, and transformation functions. In 5, you saw how records of function values can be used for the parameters needed to make an algorithm generic.

Local scoping is used for many purposes in F# programming, especially to hide implementation details that you don t want revealed outside your functions or other objects. We cover this topic in more detail in 7.

You ve also already met some other important object interface types such as System.Collections.Generic.IEnumerable<'T> and System.IDisposable. Object interface types are always implemented, and the type definition itself doesn t specify how this is done. Listing 6-5 shows an object interface type IShape and a number of implementations of it. This section walks through the definitions in this code piece by piece, because they illustrate the key concepts behind object interface types and how they can be implemented. Listing 6-5. An Object Interface Type IShape and Some Implementations open System.Drawing type IShape = abstract Contains : Point -> bool abstract BoundingBox : Rectangle let circle (center:Point, radius:int) = { new IShape with member x.Contains(p:Point) = let dx = float32 (p.X - center.X) let dy = float32 (p.Y - center.Y) sqrt(dx*dx+dy*dy) <= float32 radius
