Creational Patterns of the GoF

  1. Abstract Factory - Provide an interface for creating families of related or dependent objects without specifying their concrete classes.
  2. Builder - Separate the construction of a complex object from its representation so that the same construction process can create different representations.
  3. Factory Method - Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses.
  4. Prototype - Specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype.
  5. Singleton - Ensure a class only has one instance, and provide a global point of access to it.
