Consider the class definitions for each of the chair parts and the chair itself below.

Organizations and Objects

Note that for simplicity, each of the chair parts is just an empty object. They would each have properties and methods of their own in a real application.

Back; protected var seat: Seat; protected var legs: Using composition does not mean you will never use inheritance. In fact, when you begin composing a new object, you will frequently still need to choose an appropriate super class. This is the most common way you will work when building complex objects.

Object-oriented programming concepts: Composition and aggregation

Aggregation There is a closely related concept to composition called aggregation. In conversation the differences between composition and aggregation are often ignored. However, for the sake of accuracy, it will be covered here. Just like composition, aggregation occurs when an object is composed of multiple objects. However, with composition, the internal objects such as LegSeat and Back are owned by the main object Chair. If you destroy the Chairyou also likely want the LegSeat and Back instances destroyed because they are a composition which, together, form a single Chair.

However, imagine you make a new type of Chair called DinnerChair. DinnerChair extends Chair but it also defines a property which refers to the person currently sitting in the DinnerChair.

You could say that DinnerChair has a Person. The Chair instance certainly doesn't own the Person and you probably shouldn't assume that the Person is destroyed if the Chair is destroyed. Further, the Person exists independent of the Chair.

The Person can leave this chair and sit on another one. How SGD associates a user profile object with a user depends on the authentication mechanisms in use. For some authentication mechanisms, you might not have to create user profile objects at all. Group Object Group objects are used to associate groups of applications with an object on the User Profiles tab or groups of application servers with an object on the Applications tab. Group objects are not the same as directory objects.

Applications or application servers can only belong to one directory, but can be a member of many different groups. Members of a group can be applications, application servers, or other groups. Groups can moved or renamed without affecting group membership. Groups of application server objects can be used to associate similar application servers for load balancing.

Windows Application Object Windows application objects are used to give Microsoft Windows graphical applications to users. X Application Object X application objects are used to give X11 graphical applications to users.

Document Object Document objects are used to give documents to users.

Welcome to the Object Relations Institute for Psychotherapy and Psychoanalysis

A document object can refer to any URL. Dynamic Application Object Dynamic application objects are used with dynamic launch to enable users to select an application to run.

Application Server Object Application server objects are used to represent an application server that is used to run applications through SGD. Application servers are used with load balancing.

If you assign two or more application server objects to an application object, SGD chooses which application server to use, based on the load across the application servers.

Dynamic Application Server Object Dynamic application server objects are used with dynamic launch to enable users to select the application server that runs the application. Designing the Organizational Hierarchy You have complete control over the objects that you create to model your organizational hierarchy. However it is important to design and test your organizational hierarchy before implementing it.

The following factors affect your design: The most important influence on the design of organizational hierarchy is the Secure Global Desktop authentication mechanisms you use. For example, if you use UNIX system authentication, you can structure the hierarchy however you like. Sometimes it is a good approach to use OUs to represent the departments or offices in your organization. However, if your organization is restructured, you might have to reorganize your hierarchy.

Object Oriented programming ( OOP ) :- What is Aggregation , Association and Composition ?

The settings for user profile objects and OU objects can be inherited from the object's parent in the organizational hierarchy. For example if everyone in a department needs an application, assign the application to the OU that represents the department. Every user belonging to that OU gets the applications assigned to the OU.

Developers choose to program in the object-oriented paradigm because the proper use of objects makes it easier to build, maintain, and upgrade an application. Also, developing an application with objects that have been tested increases the reliability of the application. ActionScript 3 is an object-oriented language.

Understanding objects and knowing how to work with them is key to developing any application using ActionScript 3. This article is the first of many that will focus on object-oriented programming concepts within ActionScript 3. In it, you will learn what an object is, what a class is, how to instantiate an object, and how to work with objects using dot notation. Objects In programming terms, an object is a self-contained component that contains properties and methods needed to make a certain type of data useful.

Association (object-oriented programming)

The project management application mentioned above had a status object, a cost object, and a client object, among others. One property of the status object would be the current status of the project.

The status object would have a method that could update that status. They also allow for the actual implementation of tasks to be hidden and for particular operations to be standardized across different types of objects. Objects are the fundamental building blocks of applications from an object-oriented perspective. You will use many objects of many different types in any application you develop.
