Pronunciation

• IPA: /ˈmɪksɪn/

Noun

mixin (plural mixins)

1. (object-oriented programming) An uninstantiable class that provides functionality to be inherited by a subclass.

   Traits are somewhat between an interface and a mixin, as an interface contains only method signatures, while a trait includes also the full method definitions; on the other side mixins include method definitions, but they can also carry state through attributes, while traits usually don't.

Synonyms

• abstract base class
