[choose] PhD Defense: "Traits -- Composing Classes from Behavioral Building Blocks"

by Nathanael Schärli

Hello everybody You are invited to attend the defense of my Ph.D. entitled: "Traits -- Composing Classes from Behavioral Building Blocks" (thesis abstract below) The defense will take place on Thursday, February 3rd, 2005 at 11:00, room 002 in the IWI building (Engehaldenstrasse 8). After the defense, we will share a light lunch at the Cafeteria in building S14 (Schutzenmattstrasse 14). If you plan to join us for lunch, please let me know as soon as possible so that I can make sure there will be enough food. Kind regards, Nathanael Schärli Thesis abstract: Inheritance is well-known and accepted as a fundamental mechanism for reuse in object-oriented languages. Unfortunately, the main variants single inheritance, multiple inheritance, and mixin inheritanceall suffer from conceptual and practical problems related to software reuse and robustness with respect to changes. In a first part of this thesis, we identify and illustrate these problems. To overcome these problems, we then present traits, a simple compositional model that extends single inheritance. A trait is essentially a (parameterized) set of methods; it serves as a behavioral building block for classes and is the primitive unit of code reuse. We develop a formal model of traits that establishes how traits can be composed to form other traits or classes, and we describe how we implemented traits in Squeak Smalltalk by bootstrapping a new language kernel. We present our experimental validation in which we apply traits to refactor parts of the Smalltalk kernel and library, and we develop a programming methodology around the usage of traits and the trait browser, the tool that we implemented to take full advantage of the availability of traits in the Squeak programming environment. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ Nathanael Schärli Wuhrgasse 11 CH-4900 Langenthal, Switzerland Phone private: +41 62 922 61 21 Phone office: +41 31 631 35 47 Email: n.schaerli(a)gmx.net Web: www.iam.unibe.ch/~schaerli choose-news(a)iam.unibe.ch is a *moderated* mailing list for announcing non-commercial events related to Object Technology in Switzerland.

[choose] PhD Thesis: "High-Level Views in Object-Oriented Systems using Formal Concept Analysis" on Friday 14th, 2005 at 16:30 hs in IWI 001

by Gabriela Arevalo

You are kindly invited to the public defense of my PhD thesis " High-Level Views in Object-Oriented Systems using Formal Concept Analysis " that will take place on Friday, January 14th, 2005 at 16:30 at the room IWI 001 in Engehaldenstrasse 8 (Bern) After the defense, we will share an apero at the Cafeteria in the building S14 in Schutzenmattstrasse 14 (Bern). Best Regards, Gabriela Arevalo PhD Thesis Title: "High-Level Views in Object-Oriented Systems using Formal Concept Analysis" Abstract: Within object-oriented systems there are different meaningful dependencies between different objects. These dependencies reveal contracts, collaborations and relationships between classes, methods, packages and any development unit in the systems. In most of the cases, these dependencies are not explicit in the code. This problem is due to inadequate or out-of-date documentation and mechanisms such as dynamic binding, inheritance and polymorphism that obscure the presence of existing dependencies. These dependencies play an important part in implicit contracts between the various software artifacts of the system. It is therefore essential that a developer, who has to make changes or extensions to an object-oriented system, understands the dependencies among the classes. Lack of understanding increases the risk that seemingly innocuous changes break the implicit existing contracts in the system. In short, implicit, undocumented dependencies lead to fragile systems that are difficult to extend or modify correctly. In this thesis we develop an approach based on a methodology and a tool support to recover this implicit information and generate high-level views of a system at different abstraction levels, using a formal clustering technique called Formal Concept Analysis (FCA). With these views, we help to build the first mental model of a system. Thus the implicit or lost information is made explicit and we are able to find uses of coding styles, possible bottlenecks and weakpoints of a system, identify eventual contracts between the entities, patterns based on the dependencies and if possible propose possible solutions to correct problems in the code. With this approach we also evaluate which are the advantages and disadvantages of using a clustering technique in software reverse engineering. ------------------------------------------------------------------------ " The intelligence of his heart had taught him the uselessness of the glory " El General en su Laberinto - Garcia Marquez ------------------------------------------------------------------------ Gabriela Beatriz Arevalo Institut fur Informatik und angewandte Mathematik Gruppe Software Composition Neubrueckstrasse 10 - 3012 - Bern TE: +41 31 631 4868 (Raum: 106) Fax: +41 31 631 3355 email: arevalo(a)iam.unibe.ch http://www.iam.unibe.ch/~arevalo/ choose-news(a)iam.unibe.ch is a *moderated* mailing list for announcing non-commercial events related to Object Technology in Switzerland.
