Rosetta example: Inheritance/Multiple

+
+

Write two classes (or interfaces) Camera and MobilePhone, then write +a class CameraPhone which is both a Camera and a MobilePhone.

+

https://rosettacode.org/wiki/Inheritance/Multiple

+
+
+
package req nx
+

NX offers class-based and mixin-based multiple inheritance. The +search order of features (methods, properties) along the class +hierarchy is computed using a scheme equivalent with L3 +linearization.

+

a) Class-based multiple inheritance

+
+
+
nx::Class create Camera
+nx::Class create MobilePhone
+
+nx::Class create CameraPhone -superclasses {Camera MobilePhone}
+

Show the resulting class search order:

+
+
+
% CameraPhone info superclasses -closure
+::Camera ::MobilePhone ::nx::Object
+% [CameraPhone new] info precedence
+::CameraPhone ::Camera ::MobilePhone ::nx::Object
+

b) Mixin-based multiple inheritance

+
+
+
nx::Class create CameraPhone -mixins {Camera MobilePhone}
+% CameraPhone info mixins
+::Camera ::MobilePhone
+

Show the resulting class search order:

+
+
+
% [CameraPhone new] info precedence
+::Camera ::MobilePhone ::CameraPhone ::nx::Object
