Feather - with just a few hundred lines of code - is probably the easiest, tiniest, most obvious one, and is quite efficient too (see comparison section below). It is an adaptation of an earlier version created by Square and now maintained by Google. In this way, the DI pattern separates the responsibility of creating an object of the service class out of the client class. ActiveSpecializer is a unique technology that relies on a ground-breaking concept of using runtime information about instances of the classes.
