This document discusses advanced reflection capabilities in Pharo. It describes how instance variables are currently represented as strings but could be modeled as objects using layouts and slots. It also explains how method structures are not currently modeled at a fine-grained level and proposes using abstract syntax trees (ASTs) to represent methods as objects with sub-elements like message sends, assignments, and variable access. This would enable capabilities like behavioral reflection through meta-object links on AST nodes. The document advocates "ASTs everywhere" and sub-method reflection with meta-links in future versions of Pharo.
Object-oriented PHP provides several advantages over functional programming including easier maintenance and reuse of code through inheritance, polymorphism, and design patterns. Key concepts in OO PHP include classes, objects, inheritance, access modifiers, static methods/attributes, and cloning vs object references. An example photo gallery application is described that utilizes objects like User, Photograph, and Comment along with design patterns like strategy, iterator, and singleton.
Python allows introspection, or the ability to treat code as objects that can be examined and manipulated at runtime. It uses objects and object-oriented programming. Functions can take optional and named arguments with default values. Built-in functions like type, str, dir, and callable provide information about objects. Attributes can be accessed and functions dispatched dynamically using getattr. Lambda functions are anonymous one-line functions. Classes define objects through attributes and methods. Methods have a self parameter to access instance attributes. Special methods like __init__ and __str__ control object initialization and representation as a string. Classes can inherit from other classes and override methods while still accessing the parent implementation using super(). Operators can be overloaded to work on custom classes.
This is an intermediate conversion course for C++, suitable for second year computing students who may have learned Java or another language in first year.

Super keyword is a reference variable that is used for refer parent class object. Super keyword is used in java at three level, at variable level, at method level and at constructor level.
Reflection in C# allows examining and modifying program code, objects, and types at runtime without knowing their internal representations, enabling discovery of class information and accessing metadata. Key aspects of reflection include Type objects that represent types, MemberInfo classes that provide metadata about members, attributes that mark elements of code, and the System.Reflect namespace that contains classes for core reflection functionality. Reflection can be used for tasks like late binding, inspecting types, activating objects, and generating code on the fly.

This document discusses different data structures used in Flash and Flex, including arrays, vectors, byte arrays, and collections like ArrayCollection. It explains that arrays provide fast random access but slow insertion/deletion. Collections like ArrayCollection add sorting and filtering capabilities. Linked lists are also described as an alternative data structure that allows very fast insertion/deletion through references between nodes.
This document provides an overview of object-oriented programming (OOP) concepts. It defines what an object is, explains the differences between classes and objects, and discusses the four main principles of OOP: encapsulation, abstraction, inheritance, and polymorphism. Specific examples are given to illustrate each principle, like using a vehicle class hierarchy to demonstrate inheritance and overriding methods to show polymorphism.
This document discusses using the Doctrine ORM framework to improve object mapping in Joomla. It describes how Doctrine allows mapping between objects and database tables through associations like one-to-one, one-to-many, and many-to-many relationships. Using Doctrine's mapping features could help address Joomla's limitations with hierarchies, nested objects, and separating data structure from content models. The Jooctrine package provides an easy way to use Doctrine in Joomla extensions by handling configuration, models, and table prefixes. While Doctrine improves object mapping, fully replacing Joomla's core functionality could break many aspects that rely on its current design.

The document discusses Java serialization and common myths surrounding it. It summarizes that Java serialization allows for flexible evolution of classes while maintaining backwards compatibility through the use of serialVersionUID. It debunks common myths that Java serialization is slow, inflexible, or that changing private fields breaks compatibility. The document explains that serialization performance depends more on how streams are used rather than the underlying implementation.
The document discusses the current state and failures of the EXT:palm extension in TYPO3, which provides object to XML mapping. It outlines the extension's features for generating XML schemas from domain models and serializing/unserializing between XML and objects. However, it fails due to using global definitions, inability to output different XML, flawed TS configuration, high memory usage from multiple object representations, and slow reflection. The vision is to implement custom binding and compile it to avoid these issues and gain performance. It asks for feedback on an example alternative binding approach.
Jonathan Birch from Microsoft discusses how misuse of serialization in .NET can lead to remote code execution (RCE) vulnerabilities. He explains how serialization works and how untrusted data streams containing type information can be exploited to instantiate dangerous classes and execute arbitrary code. He provides advice on how to prevent these vulnerabilities, such as using serialization formats without type information, constraining allowed types, and validating streams have not been modified.
This document provides an overview of test automation using Selenium. It discusses reasons to automate testing such as supporting regression testing and finding defects missed by manual testing. It also discusses when not to automate, such as when an application's behavior is unstable. The document then covers the Selenium framework, its components like Selenium IDE and WebDriver, and languages it supports like Java. It also discusses concepts in object-oriented programming relevant to test automation like classes, objects, inheritance and more.
This document provides an overview of core Java concepts including object-oriented programming (OOP) principles like classes, objects, encapsulation, abstraction, inheritance, and polymorphism. It also discusses Java language benefits like being simple, portable, robust, and suitable for distributed environments. Finally, it outlines how to set up a Java development environment and write a basic "Hello World" program to get started with Java programming.
A collections framework provides a unified architecture for representing and manipulating collections of objects. It includes interfaces that define common operations on collections, implementations of those interfaces that provide reusable data structures, and algorithms that perform useful computations on collections. The main interfaces are Collection, Set, List, Queue, and Map. Collections make programming easier by reducing effort, increasing speed/quality, allowing interoperability, and fostering reuse.
The document discusses Java strings, string buffers, file I/O, serialization, dates and numbers. Some key points include:
- String objects are immutable but string references are mutable. The String constant pool stores shared strings.
- StringBuilder is like StringBuffer but not thread-safe. Both are used for file I/O with large input streams.
- File handles file paths. FileReader/Writer read/write characters. BufferedReader/Writer improve performance.
- Serialization converts objects to streams. ObjectOutputStream writes and ObjectInputStream reads objects.
- Inheritance affects serialization if the superclass is serializable. Constructors don't run on deserialization.
- Calendar manipulates dates. Date
Flush() synchronizes the database with pending changes in the persistence context. Close() ends the session and detaches all objects. Clear() detaches all objects but keeps the session open, allowing further work before needing to

2. What is deserialization about?
Its all about coverting a string to an object
• decode: (json, url-encoded, yaml, xml) => array
• denormalize: array => object
3. Where to use deserialization?
• Rest APIs
• Webapplication forms
4. But why not using JMS/Symfony?
• denormalize recursive structure within existing objects
5. Howto use the deserializer?
• define one mapping per class (explicit > implicit)
• 3 methods (getClass, getDenormalizationFactory,
getDenormalizationFieldMappings)
8. What is serialization about?
Its all about coverting a object to a string
• normalize: object => array
• encode: array => (json, url-encoded, yaml, xml)
10. But why not using JMS/Symfony?
• there is no link support
• have a consistent tool on de/serialize
11. Howto use the serializer?
• define one mapping per class (explicit > implicit)
• 4 methods (getClass, getNormalizationType,
getNormalizationFieldMappings,
getNormalizationEmbeddedFieldMappings,
getNormalizationLinkMappings)
