In this chapter, I have explored four more creational patterns.
The first pattern was a factory method. This pattern simplifies the creation of objects that depend on one another. We can implement it by following the classical object-oriented approach or in a modernized way by using interfaces and dependency injection.
From there, we moved to an abstract factory pattern. Abstract factory is a factory for factories. This pattern defines how abstract interfaces should be used to create collections of dependent objects.
The third pattern, prototype, is about making perfect copies of objects. In Delphi, we have to do this manually, and this section mostly explored the different ways of implementing the data-copying mechanism.
The last pattern in this chapter, builder, is closely related to an abstract factory pattern. It is used to split the creation of complex objects into...
