What are the elements of a design pattern?
- Pattern name: increases vocabulary of designers.
- Problem: intent, context, when to apply.
- Solution: UML-like structure, abstract code.
- Consequences: results and tradeoffs.
What problems do design patterns solve?
Polymorphism simplifies the definitions of clients, decouples objects from each other, and lets them vary their relationships to each other at run-time. Design patterns help
you define interfaces by identifying their key elements and the kinds of data that get sent across an interface
.
What are the characteristics of creational design pattern?
- A system should be independent of how its objects and products are created.
- A set of related objects is designed to be used together.
- Hiding the implementations of a class library or product, revealing only their interfaces.
- Constructing different representation of independent complex objects.
