Sound Invariant Checking Using Type Modifiers and Object Capabilities
Sound Invariant Checking Using Type Modifiers and Object Capabilities. Isaac Oscar Gariano Victoria University of Wellington [email protected] Marco Servetto Victoria University of Wellington [email protected] Alex Potanin Victoria University of Wellington [email protected] Abstract In this paper we use pre existing language support for type modifiers and object capabilities to enable a system for sound runtime verification of invariants. Our system guarantees that class invariants hold for all objects involved in execution. Invariants are specified simply as methods whose execution is statically guaranteed to be deterministic and not access any externally mutable state. We automatically call such invariant methods only when objects are created or the state they refer to may have been mutated. Our design restricts the range of expressible invariants but improves upon the usability and performance of our system compared to prior work. In addition, we soundly support mutation, dynamic dispatch, exceptions, and non determinism, while requiring only a modest amount of annotation. We present a case study showing that our system requires a lower annotation burden compared to Spec#, and performs orders of magnitude less runtime invariant checks compared to the widely used ‘visible state semantics’ protocols of D, Eiffel. We also formalise our approach and prove that such pre existing type modifier and object capability support is sufficient to ensure its soundness. 2012 ACM Subject Classification Theory of computation → Invariants, Theory of computation → Program verification, Software and its engineering → Object oriented languages Keywords and phrases type modifiers, object capabilities, runtime verification, class invariants Digital Object Identifier 10.4230/LIPIcs.CVIT.2016.23 1 Introduction Object oriented programming languages provide great flexibility through subtyping and arXiv:1902.10231v1 [cs.PL] 26 Feb 2019 dynamic dispatch: they allow code to be adapted and specialised to behave differently in different contexts.

Method Proxy-Based AOP in Scala
Vol. 0, No. 0, Z Method Proxy-Based AOP in Scala Daniel Spiewak and Tian Zhao University of Wisconsin – Milwaukee, fdspiewak,[email protected] This paper describes a fully-functional Aspect-Oriented Programming framework in Scala – a statically typed programming language with object-oriented and func- tional features. This framework is implemented as internal domain-specific lan- guages with syntax that is both intuitive and expressive. The implementation also enforces some static type safety in aspect definitions. 1 INTRODUCTION Aspect-Oriented Programming (AOP) implementations such as AspectJ provide language extensions of pointcuts and advices to insert code of crosscutting concerns into the base program through bytecode transformation. In this paper, we describe a framework to implement an AOP extension to the Scala language [13] using higher-order functions as AOP proxies 1. This framework allows programmers to specify pointcuts and aspects using a Domain Specific Language (DSL) [5] embedded within Scala. Our technique uses Scala’s higher-order functions to intercept method calls with minimal syntactic overhead imposed on the base program. This framework allows developers to define pointcuts by specifying class types and method signatures. The framework also allows access to context variables, while aspects can insert advice code before or after the advised body. The rest of the paper is organized as follows: In Section2, we present the main idea using an example. Section3 explains the syntax of pointcuts and advices. Section4 ex- plains the implementation details. We discuss the benefits and tradeoffs of our framework in Section5. and related works are in Section6. 2 EXAMPLE AOP enables developers to write code that is modularized to a point beyond the capabil- ities of vanilla object-oriented design.

AP Computer Science Basic OOP — Implementing Classes
AP Computer Science Basic OOP — Implementing Classes ORIENTATION Object-oriented programming (OOP) refers to the organization of data into classes, categories that represent a given type of “object.” An object can be a model of a real-life thing like a car, a six-sided die, or a person, or it can be a representation of something more abstract like a point in space, a menu item, or a digital clipboard. An object that belongs to a given class is called an instance of that class, and any instance of a class keeps track of its state using instance variables, or attributes. The object is created when its constructor is called, and can be interacted with by calling its methods, which may access data (accessor methods, or “getters”) or alter the object’s data (mutator methods, or “setters”). There are two important theoretical concepts in OOP: abstraction and encapsulation. Objects and the classes they belong to act as abstractions of the things they represent: a Java class called Person isn’t actually a person, of course, but a simplified representation of a person in terms of a limited number of qualities (name and age, perhaps). Other details such as hair color, nationality, and gender identity aren’t included in our abstraction of a person. Encapsulation refers to the way that a class and its methods hide away the details of a process. Someone using a QuadraticFormula class can call the hasSolutions() method to find out whether their equation has solutions without knowing what a discriminant is. The programmer and the class she has written have hidden that information away in a metaphorical “black box.” Basic OOP consists primarily of implementing classes: writing the JavaDocs, class header, constructors, attributes, and methods for an object as specified.

An Empirical Study on Encapsulation and Refactoring in the Object-Oriented Paradigm
Declaration of Authorship I certify that the work presented here is, to the best of my knowledge and belief, original and the result of my own investigations, except as acknowledged, and has not been submitted, either in part or whole, for a degree at this or any other University. Rajaa Najjar Date: 10 September 2008 An Empirical Study on Encapsulation and Refactoring in the Object-Oriented Paradigm by Rajaa Najjar A Thesis Submitted in Fulfilment of the Requirements for the Degree of Doctor of Philosophy in the University of London September, 2008 School of Computer Science and Information Systems Birkbeck, University of London 1 Abstract Encapsulation lies at the heart of the Object-Oriented (OO) paradigm by regulating access to classes through the private, protected and public declaration mechanisms. Refactoring is a relatively new software engineering technique that is used to improve the internal structure of software, without necessarily affecting its external behaviour, and embraces the OO paradigm, including encapsulation. In this Thesis, we empirically study encapsulation trends in five C++ and five Java systems from a refactoring perspective. These systems emanate from a variety of application domains and are used as a testbed for our investigations. Two types of refactoring related to encapsulation are investigated. The ‘Encapsulate Field’ refactoring which changes a declaration of an attribute from public to private, thus guarding the field from being accessed directly from outside, and the ‘Replace Multiple Constructors with Creation Methods’ refactoring; the latter is employed to remove code ‘bloat’ around constructors, improve encapsulation of constructors and improve class comprehension through the conversion of constructors to normal methods.

Perl and Ruby are both extensively used scripting languages that are applied in a wide scope of modern software applications. Applications that use Perl are Amazon.com, TicketMaster.com, and Priceline.com. Applications that use Ruby are Twitter.com, YellowPages.com, and LivingSocial.com. The purpose of discussing these languages is two-fold. First, the available quantitative comparison of these languages is limited. This paper provides essential quantitative as well as qualitative analysis that can be used as a tool for future references. Secondly, this work was performed as a trade study for the implementation of a real world database application known as PennData SpecEd Application. PennData SpecEd is used to collect records of special education students from the Commonwealth of Pennsylvania student census. This comparative study focuses first on the performance and ease of programming software components using object oriented features of both Perl and Ruby.

Arquitecturas De Microservicios Para Aplicaciones Desplegadas En Contenedores
UNIVERSIDAD POLITÉCNICA DE MADRID Escuela Técnica Superior Ingeniería de Sistemas Informáticos TRABAJO FIN DE GRADO EN INGENIERÍA DEL SOFTWARE Arquitecturas de microservicios para aplicaciones desplegadas en contenedores Autor: Carlos Jiménez Aliaga Tutora: Ana Isabel Lías Quintero Diciembre 2018 A mis padres, por haberme guiado a lo largo de los años. A mi hermana, por estar siempre ahí y ayudarme a dar lo mejor de mí. Y a mi abuela, donde quiera que esté, que siempre estuvo orgullosa de que su nieto estudiara álgebra. i | RESUMEN El estado actual de las redes de comunicaciones y la evolución de los dispositivos electrónicos, cada vez más potentes, ligeros y portátiles, ha cambiado la forma en la se consumen los servicios en línea. Los dispositivos están siempre conectados y los clientes necesitan acceder a los datos desde cualquier lugar y de forma instantánea. Esta necesidad implica una rápida adaptación de los servicios así como replicar los datos geográficamente para que puedan estar accesibles globalmente con una latencia mínima. La cuestión es, ¿cómo se consigue desarrollar servicios que cumplan las necesidades actuales de una forma eficiente a la vez que sean capaces de adaptarse rápidamente a nuevos cambios? El propósito de este proyecto de fin de grado es presentar cómo definir arquitecturas basadas en microservicios, haciendo uso de buenas prácticas, para aplicaciones desplegadas en contenedores. Para ello se hace uso de tecnologías de código abierto y multiplataforma, en concreto .NET Core para el desarrollo y Docker como motor de los contenedores. Elegir dónde y cómo desplegar las aplicaciones es un factor determinante. Se presenta el uso los orquestadores para la gestión de los contenedores (Kubernetes específicamente, que es también de código abierto) y de las plataformas Cloud donde el orquestador, las aplicaciones y servicios adicionales (como las bases de datos) son desplegados y accesibles a nivel global.

The Development of a Method to Assist in the Transformation
THE DEVELOPMENT OF A METHOD TO ASSIST IN THE TRANSFORMATION FROM PROCEDURAL LANGUAGES TO OBJECT ORIENTED LANGUAGES WITH SPECIFIC REFERENCE TO COBOL AND JAVA by Jeanette Wendy Wing A Research dissertation submitted in complete fulfilment for the requirements of the degree of Master of Technology in Information Technology in the Department of Computer Studies, Durban Institute of Technology, Durban, South Africa. Durban, December 2002 APPROVED FOR FINAL SUBMISSION ________________________________ __________________ Mr. D. A. Hunter, M.Sc.(UND) DATE SUPERVISOR i ABSTRACT Computer programming has been a science for approximately 50 years. It this time there have been two major paradigm shifts that have taken place. The first was from “spaghetti code” to structured programs. The second paradigm shift is from procedural programs to object oriented programs. The change in paradigm involves a change in the way in which a problem is approached, can be solved, as well as a difference in the language that is used. The languages that were chosen to be studied, are COBOL and Java. These programming languages were identified as key languages, and the languages that software development are the most reliant on. COBOL, the procedural language for existing business systems, and Java the object oriented language, the most likely to be used for future development. To complete this study, both languages were studied in detail. The similarities and differences between the programming languages are discussed. Some key issues that a COBOL programmer has to keep in mind when moving to Java were identified. A transformation method is proposed. The transformation method identifies the creation of two distinct types of Java classes from one COBOL program.
