With the surge of popularity of PHP 5, and with PHP 6 just around the corner, object-oriented programming is now an important consideration for PHP developers. This version-neutral book is a gentle introduction to object-oriented programming (OOP) that wont overburden you with complex theory. It teaches you the essential basics of OOP that youll need to know before moving onto a more advanced level, and includes a series of pre-packaged scripts that you can incorporate into your existing sites with the minimum of effort. It shows how OOP can be used to create reusable and portable code by walking you through a series of simple projects. The projects feature the sorts of things developers run up against every day, and include a validator for filtering user input, a simple Date class that avoids the need to remember all the esoteric format codes in PHP, and an XML generator. Teaches the fundamentals of OOP Simple projects show how OOP concepts work in the real world Pre-packaged scripts can easily be added to your own projects What youll learn PHP features, such as the Standard PHP Library (SPL), that are poorly documented or ignored by existing books How to develop classes of their own OOP in easy-to-understand language without getting bogged down in dense theory Solid foundations for developers wishing to delve more deeply into OOP How to leverage the strengths of OOP as a means for creating reusable code that can be used successfully within a procedural context How to code for both PHP 5 and 6 Who is this book for? This book is aimed at intermediate-level PHP developers who want to take their skills to the next level by exploring object-oriented programming as a way of creating reusable code for a everyday website tasks. A typical reader would be someone who has read one of the authors previous title, such as PHP Solutions, or one of the PHP books for Dreamweaverand feels ready to tackle something a little more challenging.

The definition of the second major release of the Unified Modelling Language, or UML 2.0, has been a long process. But the latest version of the object Management Group (OMG) standard will soon be ready. The large number of changes between UML 1.x and UML 2.0 have raised concerns from users: what is new in UML 2.0? Should I migrate? Is it compatible with existing UML 1.x?

Although Ruby is an easy language to learn, in the heat of action you may find that you can't remember the correct syntax for a conditional or the name of a method. This handy pocket reference offers brief yet clear explanations of Ruby's core components, from operators to reserved words to data structures to method syntax, highlighting those key features that you'll likely use every day when coding Ruby. Whether you've come to Ruby because of the Rails web development framework --Ruby's killer app -- or simply because it's a relatively clean, powerful and expressive language that's useful for a lot of applications, the Ruby Pocket Reference is organized to help you find what you need quickly. This book not only will get you up to speed on how Ruby works, it provides you with a handy reference you can use anywhere, anytime. In this book, you find essential information on: Reserved words, operators, comments, numbers, variables, ranges, and symbolsPredefined variables andglobal constantsConditional statements, method use, classes, and modules (mixins)Lists of methods from the object, String, Array, and Hash classes and the Kernel modulesprintf andtime formatting directoriesInteractive Ruby (irb) and the Ruby debuggerRuby documentation You also get information on the RubyGems package utility and Rake, a build tool similar to make.. If you're using Ruby daily and just want the facts-fast-Ruby Pocket Reference is your book.

With the award-winning book Agile Software Development: Principles, Patterns, and Practices, Robert C. Martin helped bring Agile principles to tens of thousands of Java and C++ programmers. Now .NET programmers have a definitive guide to agile methods with this completely updated volume from Robert C. Martin and Micah Martin, Agile Principles, Patterns, and Practices in C#. This book presents a series of case studies illustrating the fundamentals of Agile development and Agile design, and moves quickly from UML models to real C# code. The introductory chapters lay out the basics of the agile movement, while the later chapters show proven techniques in action. The book includes many source code examples that are also available for download from the authors' Web site. Readers will come away from this book understanding * Agile principles, and the fourteen practices of Extreme programming * Spiking, splitting, velocity, and planning iterations and releases * Test-driven development, test-first design, and acceptance testing * Refactoring with unit testing * Pair programming * Agile design and design smells * The five types of UML diagrams and how to use them effectively * object-oriented package design and design patterns * How to put all of it together for a real-world project Whether you are a C# programmer or a Visual Basic or Java programmer learning C#, a software development manager, or a business analyst, Agile Principles, Patterns, and Practices in C# is the first book you should read to understand agile software and how it applies to programming in the .NET Framework.

The problem of noise-resistance LSS control on the basis of interpreting a built-in hierarchical situational model IOHiP is considered. The method of multi-jump hypotheses for noise-resistant interpretation based on sequential analysis of the current situations hierarchy is suggested and discussed. An object-oriented IOHiP for definition of the general LSS structure and its dynamic state using the multi-jump hypotheses method is suggested. The interpretation algorithm is given in detail.

Our objective is to understand the notion of type in programming languages, present a model of typed, polymorphic programming languages that reflects recent research in type theory, and examine the relevance of recent research to the design of practical programming languages. object-oriented languages provide both a framework and a motivation for exploring the interaction among the concepts of type, data abstraction, and polymorphism, since they extend the notion of type to data abstraction and since type inheritance is an important form of polymorphism. We develop a A-calculus-based model for type systems that allows us to explore these interactions in a simple setting, unencumbered by complexities of production programming languages. The evolution of languages from untyped universes to monomorphic and then polymorphic type systems is reviewed. Mechanisms for polymorphism such as overloading, coercion, subtyping, and parameterization are examined. A unifying framework for polymorphic type systems is developed in terms of the typed A-calculus augmented to include binding of types by quantification as well as binding of values by abstraction. The typed A-calculus is augmented by universal quantification to model generic functions with type parameters, existential quantification and packaging (information hiding) to model abstract data types, and bounded quantification to model subtypes and type inheritance. In this way we obtain a simple and precise characterization of a powerful type system that includes abstract data types, parametric polymorphism, and multiple inheritance in a single consistent framework. The mechanisms for type checking for the augmented A-calculus are discussed. The augmented typed A-calculus is used as a programming language for a variety of illustrative examples. We christen this language Fun because fun instead of A is the functional abstraction keyword and because it is pleasant to deal with. Fun is mathematically simple and can serve as a b
