Implement the Create method (these will instantiate the Factory's Product objects). ![]() In some cases, this may include a default implementation. To achieve the factory pattern, there are 4 types of classes we need to implement: The factory takes care of instantiating the products that it wants to produce, and the products just need to know what rules they need to follow in order to be a product. We use a factory and product relationship to make up this pattern. Like I said earlier, the factory pattern is a creational pattern, and it gives us flexibility in creating different types of objects that inherit from the same class and then use those objects within the same code. Overviewįactory: a building or group of buildings where goods are manufactured. Let’s first visit the definition, then the implementation of the pattern, and finish with a look at some example code. This time we’ll be taking a look at another creational pattern, the factory pattern. My first post covered the singleton pattern and you can find that here. Yo yo! This is the second post that I’m writing as I’m starting to learn design patterns.
