The Abstract Factory pattern is a design pattern that we use to create families of related or dependent classes. It is like a factory of factories.
Flim-flam: to trick, deceive, swindle, or cheat. It’s only September. Or perhaps I should say, it’s already September. Either way, many of us are tired. Time flies, but we aren’t having much fun. And the work keeps piling up. The secret, apparently, is to avoid doing the work. This week I share with you some
The Factory Method pattern is a design pattern that delegates the responsibility of object creation to helper subclasses. The factory method pattern defines an interface for creating an object, but leaves the choice of its type to the subclasses.
Sanguine: cheerfully optimistic, hopeful, or confident. This has been a difficult week, which is why this email is shorter than usual and a day late. My week was dominated by three things:
The Simple Factory pattern is a design pattern that is not included in the GoF book. It is the easiest factory pattern to understand, and arguably the most commonly used.
Quest: a long or arduous search to find something. I considered a lot of words for what I wanted to write this week: Assiduous, to describe my perseverance on this topic. Lassitude, to describe a condition of lazy indifference. Specious, to describe the lack of merit in the reasons I’ve heard.
The null object design pattern is not included in the famous Gang of Four book. But it is a useful example of a good design pattern. The null object pattern defines a class that enables the processing of null values.
Accreditation: The act of certifying an educational institution or program as meeting all official formal requirements of academic excellence, facilities, curriculum, etc.
The template method pattern is a way to encapsulate algorithms. It uses inheritance to vary part of an algorithm. So we use the template method pattern when we need to support multiple variations of the same algorithm.
Furlong–firkin–fortnight (FFF): A humorous system of units based on unusual or impractical measurements.Also sometimes shortened to firkins per fortnight (FF). This week’s word is courtesy of Lewis, who actually referred to FF during his recent Object-Oriented Analysis and Design course.
