Abstract Factory Pattern
•
0 likes•363 views
The Abstract Factory pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes. It encapsulates knowledge about which concrete classes a system uses and hides how they are created and assembled. The pattern is applicable when a system needs to be independent of how product objects are created, created product families can be used independently, and products within a family are usually used together. Common implementations of the pattern include the Factory Method, Prototype, and Builder patterns. The classic Abstract Factory pattern isolates concrete classes but makes exchanging product families and enforcing consistency among products more difficult. Variations like pluggable and extensible factories aim to address these issues but also have tradeoffs around complexity and type safety.

Factory Method Design Pattern
The Factory Method pattern defines an interface for creating objects but allows subclasses to determine which object class to instantiate. This pattern encapsulates object creation and delegates it to subclasses, allowing classes to be extended without modifying the original code. The document also discusses why design patterns are useful, some strategies for using them like programming to interfaces, and themes and consequences of the Factory Method pattern like increased flexibility and eliminating hard-coded dependencies.

The document describes a heart rate and temperature monitoring system that uses sensors to detect a patient's vital signs and send alerts in emergency situations. The system includes: (1) Sensors to measure heart rate and temperature, (2) An Arduino microcontroller to process the sensor readings, (3) An Android phone for GPS location, (4) An application server to analyze the data and send SMS alerts if vital signs are abnormal, along with the patient's location. Pseudocode and diagrams are provided to illustrate how the different components communicate and function as part of the monitoring system.

GRDDL: A Pictorial Approach
This document discusses abstract and concrete syntaxes in computing languages and how GRDDL (Gleaning Resource Descriptions from Dialects of Languages) addresses some issues. It provides examples of different concrete syntaxes for arithmetic and RDF and explains that GRDDL allows authors to express RDF using XML without having to learn a specific RDF syntax or vocabulary by defining mappings from XML to RDF's abstract syntax. The document outlines some open questions about how GRDDL will handle transformation pipelines, URI resolution, validation, and its base rule.

Object Oriented Programming is revisited. It is assumed that students know OO languages so this is more of a review. We will cover concepts such as encapsulation, interfaces and polymorphism. These are important concepts that students must understand in order to write flexible and lasting code. We look at several design principles.
We also look at software design and take an example from a video games.
In this lecture we will also reveal the secret of programming which all good programmers must know.

Layers of Smalltalk Application
This document discusses several software design patterns and principles for managing dependencies between packages and modules, including:
- The Observer pattern which eliminates dependencies by having observers update independently of the subject.
- Factory patterns (factory method, abstract factory, builder) which are used to create objects while avoiding tight coupling between object producers and products.
- Singleton pattern which ensures a class only has one instance.
- Mediator pattern which defines an object to encapsulate interactions between classes, promoting loose coupling.
- Adapter pattern which converts an interface into another interface clients expect, allowing classes to work together with incompatible interfaces.
The document advises applying these patterns through refactoring to existing systems to control dependencies

Testing the untestable
1. The document discusses techniques for testing legacy production code that was not originally written with testability in mind. This includes unit testing, which allows verifying code works as expected in isolation, and writing tests before making changes to help preserve existing behavior.
2. Testing legacy code can be challenging as the code may have dependencies that are hard to isolate for testing purposes. Techniques to address this include extracting functions to new classes, replacing static dependencies with interfaces, and overriding classes to inject test dependencies.
3. While testing legacy code requires more initial work, it provides long-term benefits like reducing defects, empowering refactoring, and creating a safety net for future changes. The document provides a case study and
How effective is modularization
The document analyzes the modularity of three open source software systems: Evolution, Firefox, and Mylyn. It finds that:
1) Most changes are contained within a single module, though other modules sometimes need to be examined.
2) The distribution of lines of code changed varies between systems.
3) While the current modularization helps developers, analysis of change patterns suggests room for improvement in how the systems are modularized.

Bartlesville Dot Net User Group Design Patterns
The document summarizes several design patterns including creational, structural, and behavioral patterns. Creational patterns like abstract factory, builder, and factory method deal with object instantiation. Structural patterns like adapter, bridge, composite deal with class and object composition. Behavioral patterns like chain of responsibility, command, and observer deal with object communication and can be used to implement things like menus, toolbars, and event handling. Many of these patterns are used throughout the .NET framework in various class libraries.
Comfortable code
The document discusses best practices for code quality. It recommends writing tests first to ensure code is testable, encapsulated, cohesive, and decoupled. It also recommends separating object construction from use, favoring delegation over inheritance, and refactoring code as needed. The goal is to produce code that is testable, has no redundancy, strong encapsulation and cohesion, correct coupling, and readability.
