Purpose This document provides the requirements and functional specifications and also some technical issues fundamental to the development of SDMX Data Express1. SDMX Data Express corresponds to Work Package 3 (WP3), which is part of the project ESSnet on SDMX, and aims to develop a software application that can explore data files in SDMX format. 1.2. Project Scope The main purpose of this WP is to deliver an application that allows the users to visualize SDMX data files under different perspectives and in a user-friendly way. These visualization perspectives includes tabular (html and CSV) and graphic (charts). The user may use any SDMX data file (local or remote) whereas the related DSD (local or remote) is also provided. It will also provide a way to convert among different SDMX data messages formats (generic, cross sectional, compact) and provide an interface to help users to build a SDMX query (based on a given DSD file). Additionally it will be able to build a SDMX query message useful to retrieve data through an URL (invoking a web service, for instance). 1 Previous name “SDMX Data Express” was “SDMX Data Explorer” WP3 – Functional and Technical Specifications Pag. 4/14 ESSnet on SDMX 2. OVERALL DESCRIPTION 2.1. Product Perspective The produced application will be supported by a generic SDMX class library that can be reused in any future SDMX application. Using this generic library, programmers will be able to develop applications that operates SDMX-ML messages (create, read and write any SDMX file) in an easier way. The library will bind SDMX 2.0 standard schemas with .net classes representation, making it easy for .net developers to manipulate SDMX message files in any application (web or stand-alone). This work package will produce the following software products: a) A web application that will allow end-users to explore SDMX data; b) A generic SDMX class library, useful for programmers; c) Some web-services that will allow SDMX messages manipulation (SDMX conversion and schema validation). In the next diagram are represented the main components of the system, with user inputs and outputs expected, to help to understand the conceptual idea of SDMX Data Express. All these components will be discussed with more detail in this document.

Product Features SDMX Data Express provides a Graphic User Interface (SDMX.dx) to the common user with the following features: • SDMX Data load User can load an SDMX data file either locally, when the SDMX document is located in his computer, or by using an external URL, if the SDMX data file is located in an internet address. • Data Structure Definition (DSD) load In order to be able to manipulate the loaded SDMX data file, user must provide the corresponding DSD. To achieve this, the user may use a local DSD file, a remote DSD file (URL) or, if the Registry service is available, get the DSD from the Registry. • Tabular view In Tabular view, user may consult the loaded data either in HTML format or Comma Separated Format (CSV), which can be easily read by any Text reader or Spreadsheet application. • Chart view Using Chart view, the user is able to visualize data using a chart. The user can decide what kind of chart is the most convenient for the data (bars, columns or line chart). • Converter The Converter is a function that is able to convert from a SDMX data message format to another. WP3 – Functional and Technical Specifications Pag. 7/14 ESSnet on SDMX • Query builder The Query builder helps user to build a SDMX query message, through a visual interface, using the previously loaded DSD. • Validation After a data and structure files are loaded, user may confirm if the data file is valid. In a similar way, any SDMX query can also be validated. Beside all the previous features, available to any user, SDMX Data Express also provides some extra resources to developers: • SDMX library (SDMX.lib) The SDMX library is responsible for providing methods to manipulate any SDMX document. This library is able to represent, using .net classes, SDMX 2.0 standard schemas and, as a consequence, any SDMX data message file. The functions available to the user (using a graphic user interface) should be produced in this library. • Web Service (SDMX.ws) The web service exposes operations responsible for validation and conversion, of SDMX documents, through http request. WP3 – Functional and Technical Specifications Pag. 8/14 ESSnet on SDMX 2.3. Operating Environment SDMX Data Express will be delivered, primarily, as a web application. It should run on any 32-bits Microsoft Windows operating system but, considering it’s a web application, it’s necessary to have also installed the Internet Information Services (or Internet Information System) to be able to run. The option of having SDMX Data Express delivered as a web application was adopted because it was considered a better way to have this kind of tool available to the user, through a browser, anywhere and anyplace. To achieve this, the SDMX Data Express will be available in a web server over the internet. It should be available in the ESSnet on SDMX web site. In addition, a web service will also be produced and exposed in the same web site. 2.4. Design and implementation constraints • Programming language The programming language adopted for the development of SDMX Data Express is C-Sharp (C#), which is part of Microsoft .Net framework 3.0. In order to assure that all participants will develop the software modules in a similar way, it is recommended to use some C# conventions and rules (see Annex I). • Development Environment As the preferable Integrated Development Environment (IDE), it is proposed to be used the Visual Studio 2008, although Visual Web Developer 2008 Express WP3 – Functional and Technical Specifications Pag. 9/14 ESSnet on SDMX can also be used (this IDE is freely available at Microsoft web site, http://www.microsoft.com/express/vwd/). • Software licence and support All software produced must be developed under European Union Public Licence (EUPL). Although all the software will be delivered as open source the development team will not guarantee to give support to developers or users after the conclusion of this project. • Standards-based SDMX Data Express should comply with established industry standards, like XML, SDMX and HTML. The standards-compliance will not only apply to application development but also to design, platform/infrastructure and other parts of the SDMX Data Express. In terms of web service, cross-platform interoperability should be guaranteed according to the WS-I Basic Profile 1.1 (see http://www.ws-i.org/). 2.5. User documentation Along with the software delivered some documentation will also be produced. This documentation includes user manual and installation guide, but additionally some basic developer guide will also be delivered. WP3 – Functional and Technical Specifications

  • Declaring Data Member Public C
    Declaring Data Member Public C Rickard brooch stickily. Interceptive and hamulate Connie enure, but Norbert crossways extinguishes her patroness. Is Mario estimated or electrotonic when strangulating some moribundity deified deeply? Optimize for declaring data member public If dynamic allocation is necessary, prefer to keep ownership with the code that allocated it. This process of creating an object from a class is known as instantiation. Here is the quite surprising output of the program. Data attributes need not be declared; like local variables, they spring into existence when they are first assigned to. The term __________ means the ability to takemany forms. In many cases, this is not a problem, but it is a problem in some cases. Use rvalue references only in certain special cases listed below. By default, functions and data members of the class are public. How many data members should be in every class and why? Is it acceptable to omit default constructors in a class? For accessing the data, the declaration of a friend function should be done inside the body of a class starting with the keyword friend. The constructor is declared much like a normal member function but it will share the name of the class and it has no return value. Spirit would be impossible without it. The basic idea is really very simple. Giving sensible names to types and variables is much better than using obscure names that you must then explain through comments. Special member functions called constructors and destructors. This makes it impossible for the class to ensure that invariant properties of that variable are respected.

Vorsitzende: Univ.-Prof. Gudrun Klinker, Ph.D. Prüfer der Dissertation: 1. Univ.-Prof. Michael Beetz Ph.D., Universität Bremen 2. Univ.-Prof. Dr. Alin Albu-Schäffer Die Dissertation wurde am 19.08.2015 bei der Technischen Universität München ein- gereicht und durch die Fakultät für Informatik am 26.02.2016 angenommen. Abstract With the development of mobile robotic platforms that can operate in domestic do- mains such as a human household, for instance Willow Garage’s PR2, solving tasks such as cleaning up or cooking food has become possible. The software that controls these robots became more and more complex and recent research provides solutions for navigation, manipulation and perception. With rising complexity of the tasks to be performed, the requirements for a high level executive that orchestrates arm mo- tions, navigation and perception changed towards a tight integration of planning, reasoning and action execution. This thesis describes CRAM, a complete framework for implementing cognitive high-level robot control programs to enable robotic agents to execute their tasks more robustly, reliably and flexibly. CRAM combines a powerful language for programming robot actions with sophisti- cated reasoning mechanisms. This allows the programmer to state plans more ab- stractly by letting the robot make decisions based on its current belief about the en- vironment and the predicted future course of actions.

Introduction Stata’s two programming languages, ado and Mata, each support object-oriented programming. This manual entry explains object-oriented programming in Mata. Most users interested in object-oriented programming will wish to program in Mata. See[ P] class to learn about object-oriented programming in ado. Example The following example is explained in detail in Description. class coord { real scalar x, y real scalar length(), angle() } real scalar coord::length() { return(sqrt(x^2 + y^2)) } real scalar coord::angle() { return(atan2(y, x)*360/(2*pi())) } class rotated_coord extends coord { real scalar theta real scalar angle() void new() } 1 2 class — Object-oriented programming (classes) real scalar rotated_coord::angle() { return(super.angle() - theta) } void rotated_coord::new() { theta = 0 } One could use the class interactively: : b = rotated_coord() : b.x = b.y = 1 : b.angle() // displayed will be 45 : b.theta = 30 : b.angle() // displayed will be 15 Note that executing the class as if it were a function creates an instance of the class.

  • Chapter 10: Object-Oriented Programming in Labview
    Bitter, Rick et al "Object-Oriented Programming in LabVIEW" LabVIEW Advanced Programming Techinques Boca Raton: CRC Press LLC,2001 Object-Oriented 10 Programming in LabVIEW This chapter applies a different programming paradigm to G: Object-Oriented Pro- gramming (OOP). New languages like Java and its use on the Internet have created a lot of interest in this programming paradigm. This chapter explains the concepts that make object-oriented programming work, and applies them to programming in LabVIEW. This chapter begins with definitions of objects and classes. These are the fun- damental building blocks of OOP. Key definitions that define OOP are then presented which give a foundation for programmers to view applications in terms of their constituent objects. Once the basics of OOP are described, the first stage of objects is presented-- object analysis. Fundamentally, the beginning of the design is to identify the objects of the system. Section 10.4 discusses Object Design, the process by which methods and properties are specified. The interaction of objects is also defined in the design phase. The third and last phase is the Object Programming phase. This is where the code to implement the methods and properties is performed. This type of structuring seems foreign or even backward to many programmers with experience in structured languages such as LabVIEW. Object-oriented is how programming is currently being taught to computer science and engineering students around the world. A significant amount of effort has been put into the design of a process to produce high-quality software. This section introduces this type of phi- losophy to LabVIEW graphical programming.

  • Coding Conventions: 1.03
    Fiercefun.com Coding Conventions: 1.03 Please note that these conventions are not optional. Any project not following these conventions will not be used in production. Coding conventions are style guidelines for programming. They typically cover: ● Naming and declaration rules for variables and functions. ● Rules for the use of white space, indentation, and comments. ● Programming practices and principles Fierce Fun primarily uses C# and scripting languages (ActionScript, JavaScript, PHP) so our coding conventions follow those used primarily in Java/JavaScript standards. The Importance of Naming Choosing good names for variables, functions and classes is critical to creating code that is easy to use and easy to understand. You should always take the time to think about whether you have chosen the right name for something. Properly naming and commenting items is one of the most critical task of software projects. At all times, developers should care about and adhere to this critical task. Version Control GitHub Unity Collaborate Links Our conventions are based on the following https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/inside-a-program/coding- conventions C# https://pear.php.net/manual/en/standards.php (PHP) Fierce Fun ©. Private and Confidential General Coding Practise At Fierce Fun, we classify code as development and production. Development Code Development is what you work on day-to-day. It can be messy at time, undocumented and buggy. Effectively it is your in-progress work and only you will see it. Production Code Production code is what you submit for review on a weekly basis. This code could be used in the final production build so it should be clean, organised and commented before submitting.
