Instead of embedding this code directly in the class which calls the algorithm, a better approach is to decouple this code into another class which implements Factory method. and Builder. Abstract Factory specializes in creating families of related objects. How to implement the factory method pattern in C++ correctly. Why did the International Telecommunications Union denote CY for Canada? Domain Model Design - Best Practices for Robust Fluency, Encapsulation, and Extensibility. The Builder Pattern.

Be careful that you do not confuse the name of a pattern (which is a reusable technique involving, almost always, multiple objects / participants / roles), and the name of a specific role in a pattern. consider a builder when faced with many constructor patterns, the algorithm for creating complex object should be independent of the parts that make up the object and how they are assembled, -constructs and assmbles parts of the product by implementing the builder interface, -Specifies interface for creating parts of product, -Constructs an object using the builder interface, -represents the complex object under construction, Provides an interface for creating families of related or dependent objects without specifying their concrete classes, user interface toolkit needs to support multiple look-and-feel options, -a system should be independent of how its products are created, -declares an interface for operations that create abstract product objects, -implements the operations to create concrete product objects, -declares an interface for a type of product object, -defines a product object to be created by the corresponding concrete factory, -uses only interfaces declared by AbstractFactory and AbstractProduct classes. So thought of an idea to reduce code clutter using factory pattern. Now the specific builder FordBuilder or GMBuilder can execute the process or recipe for building a sedan or truck as requested by a customer, making calls on makeFrame(), makeDoor() and makeWheel() as needed, safe in the knowledge that that what comes off the line is a proper sedan or truck and not some non-functioning chimera.

Note that while the director is giving the directions, its the builder that knows how those parts fit together to make a coherent whole. Builder ( VehicleBuilder ) specifies an abstract interface for creating parts of a Product object ConcreteBuilder ( MotorCycleBuilder, CarBuilder, ScooterBuilder ) constructs and assembles parts of the product by implementing the Builder interface defines and keeps track of the representation it creates This pattern includes four main roles: AbstractFactory declares an interface for operations that create product object.

Although you will find examples of it also being used to return Builder, Prototypes, Singletons or other design pattern implementations. Builder pattern is used to instantiate complex objects and abstract factory pattern is used to create group of similar object without requiring the exact classes. Builder focuses on constructing a complex object step by step. Builder - A pattern for creating complex objects by separating the construction process from the final product.
