SoC and the Apex Common Library Tutorial Series Part 1: Introduction to the Separation of Concerns Design Principle
ByCoding With The Force Inc April 5, 2021December 13, 2023

What is the Separation of Concerns Design Principle? Basically separation of concerns is the practice of putting logical boundaries on your code. Putting these logical boundaries on your code helps make your code easier to understand, easier to maintain and much more flexible when it needs to be altered (and every code base ever has…

SoC and the Apex Common Library Tutorial Series Part 3: The Factory Method Pattern
ByCoding With The Force Inc April 7, 2021December 13, 2023

What is the Factory Method Pattern? The factory method pattern allows you to create objects (or instantiate classes) without having to specify the exact class that is being created. Say for instance you have a service class that can be called by multiple object types and those object types each have their own object specific…

ByCoding With The Force Inc April 8, 2021December 13, 2023

What is the fflib_Application class? Quality question… I mean honestly wtf is this thing? Lol, sorry, let’s figure it out together. The fflib_Application class is around for two primary purposes. The first is to allow you an extremely abstract way of creating new instances of your unit of work, service layer, domain layer and selector…

SoC and the Apex Common Library Tutorial Series Part 5: The Unit of Work Pattern
ByCoding With The Force Inc April 9, 2021December 13, 2023

What is the Unit of Work Pattern (UOW) A Unit of Work, “Maintains a list of objects affected by a business transaction and coordinates the writing out of changes and the resolution of concurrency problems”. The goal of the unit of work pattern is to simplify DML in your code and only commit changes to…

SoC and the Apex Common Library Tutorial Series Part 6: The fflib_SObjectUnitOfWork Class
ByCoding With The Force Inc April 10, 2021December 13, 2023

What is the fflib_SObjectUnitOfWork class? It is a foundation built to allow you to leverage the unit of work design pattern from within Salesforce. Basically this class is designed to hold your database operations (insert, update, etc) in memory until you are ready to do all of your database transactions in one big transaction. It…

SoC and the Apex Common Library Tutorial Series Part 7: The Service Layer
ByCoding With The Force Inc April 11, 2021December 13, 2023

What is the Service Layer? The Service Layer, “Defines an application’s boundaries with a layer of services that establishes a set of available operations and coordinates the application’s response in each operation”. – Martin Fowler This essentially just means that the service layer should house your business logic. It should be a centralized place that…

SoC and the Apex Common Library Tutorial Series Part 9: The Template Method Pattern
ByCoding With The Force Inc April 13, 2021December 11, 2023

What is the Template Method Pattern? The Template Method Pattern is one of the more popular Behavioral Design Pattern. The Template Design Pattern basically is creating a genericized skeleton class that a sub class can extend and add functionality to. The genericized skeleton class has some core functionality pre-built, but expects you to fill out…

ByCoding With The Force Inc April 14, 2021December 13, 2023

What is the Domain Layer? The Domain Layer is, “An object model of the domain that incorporates both behavior and data”. – Martin Fowler In most coding languages you need to connect to the database, query for the data and then you create wrapper classes to represent each underlying table in your database(s) to allow…
