Many of the designations used by manufacturers and sellers to distinguish their products are claimed
as trademarks. Where those designations appear in this book, and the publisher was aware of a trademark
claim, the designations have been printed with initial capital letters or in all capitals.
The author and publisher have taken care in the preparation of this book, but make no expressed or

If you’ve ever read a technical book, you’ve seen the acknowledgments and understand that
even though there are (in this case) two names on the front cover, a lot of other folks behind
the scenes make the whole process work.
In particular, we’d like to single out Denise Santoro Lincoln, who was our primary wrangler.
We gave her “polenta” of problems, which she handled with taste, grace, and humor. Thanks
also to Clay Andres and Jeff LaMarche, who helped make sure we didn’t tell you any lies.
Welcome to Learn Objective-C on the Mac! This book is designed to teach you the basics of the
Objective-C language. Objective-C is a superset of C and is the language used by many (if not
most) applications that have a true OS X or iOS look and feel.
In addition to presenting Objective-C, this book introduces you to its companion, Apple’s Cocoa
(for OS X) and Cocoa Touch (for iOS) toolkits. Cocoa and Cocoa Touch are written in Objective-C
and contain all the elements of the OS X and iOS user interfaces, plus a whole lot more. Once
you learn Objective-C, you’ll be ready to dive...
Since Kant, philosophy has been obsessed with epistemological questions pertaining to the relationship between mind and world and human access to objects. In The Democracy of Objects Bryant proposes that we break with this tradition and once again initiate the project of ontology as first philosophy. Drawing on the object-oriented ontology of Graham Harman, as well as the thought Roy Bhaskar, Gilles Deleuze, Niklas Luhman, Aristotle, Jacques Lacan, Bruno Latour and the developmental systems theorists, Bryant develops a realist ontology that he calls “onticology”.
Dialogues may be seen as comprising commonplace routines on the one hand and specialized, task-specific interactions on the other. Object-orientation is an established means of separating the generic from the specialized. The system under discussion combines this objectoriented approach with a self-organizing, mixed-initiative dialogue strategy, raising the possibility of dialogue systems that can be assembled from ready-made components and tailored, specialized components.
With the release of .NET 3.5, the C# language has been enhanced to support a great number of new programming constructs, many of which are used to enable the LINQ API. This chapter, you will learn the role of implicit typing of local variables, partial methods, automatic properties, extension methods, anonymous types, and object initialization syntax.
After studying this chapter you will be able to understand: What classes, objects, methods and instance variables are; how to declare a class and use it to create an object; how to declare methods in a class to implement the class's behaviors; how to declare instance variables in a class to implement the class's attributes; how to call an object's method to make that method perform its task;...
Object Oriented Programming - Lesson 5: Encapsulation, Overloading and Aggregation includes Encapsulation (Visibility scope, Data hiding), Overloading (Principles, Constructor overloading), Aggregation (Principles, Order of initialization).
Object Oriented Programming - Lesson 6: Inheritance presents Inheritance (Principles, Inheritance hierarchy, Sub class definition, Order of initialization), Reusing through class, To provide new functionality to a subclass.
Chapter 3 introduction to Classes and Objects. In this chapter you will learn: What classes, objects, methods and instance variables are; how to declare a class and use it to create an object; how to declare methods in a class to implement the class’s behaviors; how to declare instance variables in a class to implement the class’s attributes; how to call an object’s method to make that method perform its task;...
In chapter 7 you will learn: What arrays are, to use arrays to store data in and retrieve data from lists and tables of values, to declare an array, initialize an array and refer to individual elements of an array, to use the enhanced for statement to iterate through arrays, to pass arrays to methods, to declare and manipulate multidimensional arrays, to write methods that use variable-length argument lists.
This chapter introduces Object-Oriented Systems Analysis and Design with the Unified Modeling Language, Version 2.0. First, the chapter introduces the basic characteristics of object-oriented systems. Second, it introduces UML 2.0. Third, the chapter overviews Object-Oriented Systems Analysis and Design and describes the Unified Process. Finally, based on the Unified Process and the UML 2.0, the chapter provides a minimalist approach to Object-Oriented Systems Analysis and Design with UML 2.0.
AutoCAD 2011 is designed to work in a Windows operating system. In
general, to open AutoCAD 2011, double-click on the AutoCAD 2011
shortcut in the Windows desktop ( Fig. 1.1 ). Depending on how details in
Profi les/Initial Setup … in the Options dialog ( Fig. 1.16 , page 13 ), the
Welcome dialog ( Fig. 1.2 ) may appear. This dialog allows videos showing
Fig. 1.1 T he AutoCAD methods of working AutoCAD 2011, to be selected from a list of icons.
The book you’re holding in your hand (or reading on the screen) owes its genesis to a
tongue-in-cheek exchange with Steve Fleischer of Flying Tiger Web Design (www.
flyingtigerwebdesign.com), who suggested I should write Powers Object-Oriented PHP.
Actually, he phrased it rather differently. If you take the initial letters of the suggested title,
you’ll get the drift . . . But Steve had an important point: he felt that books on object-oriented
programming (OOP) frequently assumed too much prior knowledge or weren’t easily
adaptable to PHP in a practical way.
This module provides students with the theory and syntax for creating and
destroying objects in a C# application.
After completing this module, students will be able to:
Create objects by using the new operator.
Use constructors to initialize objects.
Create overloaded constructors that can accept varying parameters.
Describe the lifetime of an object and what happens when it is destroyed.
Inherit from IDisposable interface and implement Dispose method.
After completing this lesson, you should be able to do
• Create and manage initialization parameter files
• Start up and shut down an instance
• Monitor and use diagnostic files.
Initialization Parameter Files
• Entries are specific to the instance being started
• Two types of parameters:
– Explicit: Having an entry in the file
The promoter or sponsor must be involved in all of the planning phases to ensure a
successful event. Often, the promoter is interested in monetary gain more than he or she is
interested in public safety. If this appears to be his or her primary goal, local agency
participation is essential. You may encourage the promoter to cooperate by linking
attendance at planning meetings with the permit process and issuance. For example, the
permit to host the event may require the promoter’s presence at the initial planning
meeting. Teamwork promotes successful events.
Dennis Ritchie at AT&T Bell Laboratories pioneered the C programming language in
the early 1970s. However, this programming language did not begin to gain widespread
popularity and support until the late 1970s.This was because, until that time, C compilers
were not readily available for commercial use outside of Bell Laboratories. Initially, this
growth in popularity was also partly spurred by the equal, if not faster, growth in popularity
of the UNIX operating system, which was written almost entirely in C.
Brad J. Cox designed the Objective-C language in the early 1980s.
Despite the prominence of gender issues in the IADGs, effectiveness of development cooperation has not focussed
enough on outcomes of gender equality and women’s rights in terms of either the inclusion of indicators tracking the
focus of development cooperation on gender equality or the participation of women’s organisations in initiatives to hold
actors to account. 2012 analysis conducted for the DCF shows that aid/partnership policies, targets and mutual
accountability processes do not focus adequately on the gender impact of development cooperation.
