Instead of one set-routine, it h For flexibility, EiffelVision 2 is built using the bridge pattern. This means that every platform-dependent component of the library consist of two classes, plus an implementation class for each platform (currently two). One is the interface. All the features of interfaces do nothing except delegate the call to the implementation object which is coupled to it. This object has the static type of the implementation-interface with the name of the interface class, with an "_I" suffix. The implementation classes (with an "_IMP" suffix) then inherit from this implementation-interface class to implement platform-specific features. At run time, these platform-specific implementation objects (instantiated from the "_IMP" classes) are then polymorphically attached to the to the "_I"-typed attributes (typically named "implementation") to provide the platform-specific services. - +{{SeeAlso| The book titled ''Design Patterns: Elements of Reusable Object-Oriented Software'' by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, contains a complete description of the Bridge Pattern.}}
