The getters in the abstract superclasses can even be defined as abstract to require concrete implementations to define those fields. Basically the concrete subclasses define the actual fields that the Builder should support, and the Getter annotation results in the corresponding superclass methods to be overridden. Lombok makes it simple to create builder objects in much the same way that it enables easy POJO creation. Factory pattern removes the instantiation of actual implementation classes from client code.
