  • Using Generics To Build Fluent API's In Java
  • extends BaseClass
  • super(ChildClass.class)
  • ...19 more annotations...
  • accomplish the same idea using generics
  • creates a bad sort of dependency where we need to update the base class every time we make a new derived class. Not good!
  • superclass requests information about the child, and the child provides it
  • (CHILD)
  • <CHILD extends BakedGood<CHILD>>
  • CHILD
  • (CHILD)
  • CHILD
  • abstract
  • extends BakedGood<Cake>
  • The type parameter is saying “the Child class must extend Base<Child>”, forcing the Child class to provide its own type to the type system
  • Now that we can return the derived class in our chained method calls we are free to alternately call methods from the base class and the derived class
  • All of the normal polymorphic abilities are retained (you can see that we’ve implemented the abstract bake() method required by BakedGood)
  • .bake()
