Design Patterns

Design Patterns

1. Creational

   • Factory Method
     • Allows subclasses to instantiate their own objects
   • Abstract Factory
     • Offers the interface for creating a family of related objects, without explicitly specifying their classes.
   • Singleton
     • - Ensure that only one instance of a class is created - Provide a global access point to the object
   • Object Pool
     • Reuses and shares objects that are expensive to create

2. Structural

   • Facade
     • Simplifying the interface of a complex system
   • Bridge
     • Hiding variation of implementation
   • Adapter
     • Hide variation of interface design
   • Decorator
     • Modular assembler of complex components

3. Behavorial

   • Template Method
     • Hiding implementation of algorithms
   • Strategy
     • Hiding variation of algorithms
   • Observer
     • Handles notifications of changed methods and subscribed classes are updated accordingly
