Mixins allow document authors to define patterns of property value pairs, which can then be reused in other rulesets. The mixin name is a class selector that identifies the mixin being declared. The @mixin keyword must be followed by the mixin name and a declaration block. The following line...

In this scenario, each capability of a light is its own interface; only classes inherit multiple interfaces. This sample shows one scenario where you can define discrete features that can be mixed into classes. You declare any set of supported functionality by declaring which interfaces a class ...
Some things to keep in mind when using mixins though: TheObject.assign(both in object and class implementation) does only a shallow copy of the mixin properties. There can be potential name clashes while using properties from different mixins (the diamond problem in multiple inheritance) ...
Unfortunately, the use of inheritance over composition often leads to systems that, paradoxically, increase code duplication. The main problem lies in the fact that inheritance can directly delegate to only one other class (the parent class), as opposed to composition, where the object can ...
More than one description can be generated for each image. Descriptions are ordered by their confidence score. Descriptions may include results from celebrity and landmark domain models, if applicable. Two input methods are supported – (1) ...
A mixin is essentially an abstract class that is parameterized over a (super)class. Each mixin consists of three parts: (i) methods defined in the mixin; (ii) expected methods, that must be provided by the superclass; (iii) redefined methods, where next can be used to access the (old...
One of the strongest arguments made for multiple inheritance in C++ is for the use of mixins. However, a more interesting and elegant approach to mixins is using parameterized types, whereby a mixin is a class that inherits from its type parameter. In C++, you can easily create mixins bec...
