Creational Design Pattern

Creational patterns provide various object creation mechanisms, which increase flexibility and reuse of existing code.

In the world of software engineering, Creational design pattern means the creation of objects and classes. These design patterns are valid for creating objects. These patterns attach clearness to object creation by controlling it. 

They are classified into Class and Object creational patterns, where Class-creational deals with class instantiation and Object-creational deals with Object creation. Below are five summaries of acclaimed creational design patterns:

  • Prototype Method
    • This method is a creational design pattern that permits cloning objects, even complex ones, without joining to their specific classes. Simply put, create new items by copying this method.
  • Abstract Factory Method
    • This method defines an interface for creating all specific products but leaves the actual product creation to concrete factory classes.
  • Singleton Method
    • We use this method when we want to restrict the instantiation of a class to one object. It is a type of creational pattern that involves only one class to create methods and specified objects. It helps us to provide a global point of access to the instance created.
  • Builder Method
    • This method is a rare design pattern that helps us in building a complicated object using simple objects and uses an algorithmic approach. Exceptionally, the builder’s method is beneficial when we need to create an object(complex) with lots of possible configuration options.
  • Factory Method
    • This method is a creational design pattern used to create concrete implementations of a common interface. It separates the process of creating an object from the code that depends on the interface of the object.
