Little Sugar ( Mixins in Java)

Mixin ?? what is a mixin ...

Thats what i wondered when i cam accross the phrase . A Mixin is a way of adding features to the core functionlaity of a class . It is different from extending the class , cause it generally pertains to adding features not related to the core or default behaviour of a class .

A little example will make things clear . Say you have a small class Person that represents a person wholly . Not if you want to compare 2 instances of Person , you could implement the Comparable interface . By implementing the Comparable interface you add a functionlity that is not directly related to a Person object but is a help ful feature .

So a simple way to implement a Mixin is to implement an interface .. so much for buzz words...
