Design Patterns


Software Design Patterns

Design patterns are common architectural approaches that have been observed in software engineering practices.

A pattern is a description of an approach, how it is expressed in a programming language and what it is used for.

Solid Principles

In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible, and maintainable.

Gama Categorization (Gang of Four)

Design patterns are typically slit into three categories

Creational

Deal with the construction of objects;constructor, DI, reflection;single statement, stet-by-step

Structural

Defines the structure (Interfaces, all API)

Behavioural

Focus on communication among objects

Other Patterns

SOLID (4/5) - Interface segregation principle

Interface segregation principle In the field of software engineering, the interface-segregation principle (ISP) states that no client should be forced to depend on methods it does not use. ISP splits interfaces that are very large into smaller and more specific ones so that clients will only have to know about the methods that are of interest to them. Such shrunken interfaces are also called role interfaces. ISP is intended to keep a system decoupled and thus easier to refactor, change, and redeploy. using   System ; namespace   interfacesegregation {      public   class   Document       {     }      public   interface   IMachine       {          void   Print ( Document   d );          void   Scan ( Document   d );     ...

SOLID (1/5) - Single Resposibility Principle

 SOLID (1/5) - Single Resposibility Principle The single-responsibility principle (SRP) is a computer-programming principle that states that every class in a computer program should have responsibility over a single part of that program's functionality, which it should encapsulate. All of that module, class or function's services should be narrowly aligned with that responsibility. In the following example we have a TodoList class which only handles it's own functionality logic, and then we have a Persistance class which handles the saving logic, hence keeping the concerns separeted. using   System ; using   System . Collections . Generic ; namespace   Journal {      public   class   TodoList     {          private   readonly   List < string >  _entries  =  new   List < string >();          private...
