Ioc Containers in Spring
301AA - Advanced Programming Lecturer: Andrea Corradini [email protected] http://pages.di.unipi.it/corradini/ AP-2018-11: Frameworks and Inversion of Control Frameworks and Inversion of Control • Recap: JavaBeans as Components • Frameworks, Component Frameworks and their features • Frameworks vs IDEs • Inversion of Control and Containers • Frameworks vs Libraries • Decoupling Components • Dependency Injection • IoC Containers in Spring 2 Components: a recap A software component is a unit of composition with contractually specified interfaces and explicit context dependencies only. A software component can be deployed independently and is subject to composition by third party. Clemens Szyperski, ECOOP 1996 • Examples: Java Beans, CLR Assemblies • Contractually specified interfaces: events, methods and properties • Explicit context dependencies: serializable, constructor with no argument • Subject to composition: connection to other beans – Using connection oriented programming (event source and listeners/delegates) 3 Towards Component Frameworks • Software Framework: A collection of common code providing generic functionality that can be selectively overridden or specialized by user code providing specific functionality • Application Framework: A software framework used to implement the standard structure of an application for a specific development environment. • Examples: – GUI Frameworks – Web Frameworks – Concurrency Frameworks 4 Examples of Frameworks Web Application Frameworks GUI Toolkits 5 Examples: General Software Frameworks – .NET – Windows platform. Provides language interoperability – Android SDK – Supports development of apps in Java (but does not use a JVM!) – Cocoa – Apple’s native OO API for macOS. Includes C standard library and the Objective-C runtime. – Eclipse – Cross-platform, easily extensible IDE with plugins 6 Examples: GUI Frameworks • Frameworks for Application with GUI – MFC - Microsoft Foundation Class Library. -

Mac OS X: an Introduction for Support Providers
Mac OS X: An Introduction for Support Providers Course Information Purpose of Course Mac OS X is the next-generation Macintosh operating system, utilizing a highly robust UNIX core with a brand new simplified user experience. It is the first successful attempt to provide a fully-functional graphical user experience in such an implementation without requiring the user to know or understand UNIX. This course is designed to provide a theoretical foundation for support providers seeking to provide user support for Mac OS X. It assumes the student has performed this role for Mac OS 9, and seeks to ground the student in Mac OS X using Mac OS 9 terms and concepts.

An object-oriented framework is a set of classes that embodies an abstract design for solutions to a family of related prob- lems. The work presented is based on and has its origin in industrial contexts where object-oriented frameworks have been developed, used, evolved and managed. Thus, the results are based on empirical observations. Both qualitative and quanti- tative approaches have been used in the studies performed which cover both tech- nical and managerial aspects of object-oriented framework technology. Historically, object-oriented frameworks are large monolithic assets which require several design iterations and are therefore costly to develop. With the requirement of building larger applications, software engineers have started to compose multiple frameworks, thereby encountering a number of problems. -

Support for custom protocols design. -
Agent-Based Modeling with the JABM Toolkit
Noname manuscript No. (will be inserted by the editor) Agent-Based Modeling with the JABM Toolkit Steve Phelps Centre for Computational Finance and Economic Agents (CCFEA) [email protected] the date of receipt and acceptance should be inserted later Abstract In many areas of science, agent-based models have become increasingly important. These models are often sufficiently complex that deriving closed-form solutions for quantitative aspects of their macroscopic behaviour is often impracti- cal if not impossible, and hence they are often analysed using discrete-event simu- lation and Monte-Carlo methods. In this paper we give an overview of agent-based modeling with an emphasis on its application to multi-agent systems research, and show how a software design pattern called \dependency injection" can be used to implement highly configurable simulation models which are able to incorporate various assumptions about agents' rationality and learning. We then show how these ideas have been implemented in the Java Agent-Based Modelling (JABM) toolkit | an open-source framework for building agent-based models. 1 Introduction In this paper we describe practical aspects of developing agent-based simulation models with particular emphasis on agent-based computational economics and work carried out within the trading-agent design and analysis community. We introduce a new software framework for building agent-based models | the Java Agent Based Modeling (JABM) toolkit1. Work on JABM arose out of an earlier project | Java Auction Simulator API (JASA)2 | which was designed as a toolkit for performing experiments in Agent-based Computational Economics (ACE)3 and was subsequently used as the basis of the JCAT software used to run the CAT tournament which is part of the Trading Agent Competition (Cai et al, 2009). -
The Operating System the Operating System (OS) Is the He Low-Level Software Which Handles the Interface to Peripheral Hardware
The Operating System The Operating System (OS) is the he low-level software which handles the interface to peripheral hardware, schedules tasks, allocates storage, and presents a default interface to the user when no application program is running. Main functions: - 1. Provides instructions to display the on screen elements with which you interact. Collectively, these elements are known as the user interface. 2. Loads programs into the computers memory so that you can use them. 3. Co-ordinates how programs work with the CPU, RAM, keyboard, mouse, printer and other hardware as well as with software. 4. Manages the way information is stored on and retrieved from disks. The User Interface With an OS you see and interact with a set of items on the screen, the user interface. Graphical User Interface - Most current OS provide a graphical user interface (GUI). Apple computer introduced the first GUI with its Macintosh computer in 1984. GUIs are so called because you use a mouse (or other pointing device) to point at graphical objects on the screen. The Desktop - The coloured area that is seen on the screen. The pictures stand for items you might see on a real desktop such as “my computer”. Icons - Icons are pictures that represent the parts of the computer you work with. Software designers try to design the icons so that they look like what they represent. You interact with your computers resources by activating the icon that represent the resource. This is done by using a pointing device. The Taskbar and the Start Button (windows only) - When you start a program a button appears for it on the taskbar – an area at the bottom of the screen whose purpose is to display the buttons for the programs you are running.
