In fact, they are hard to locate (scattering) and may give rise to multiple ripple effects (tangling). Aspect oriented programming offers mechanisms to factor them out into a modular unit, called an aspect. Aspect identification in existing code is supported by means of dynamic code analysis. Execution traces are generated for the use cases that exercise the main functionalities of the given application. The relationship between execution traces and executed computational units (class methods) is subjected to concept analysis. In the resulting lattice, potential aspects are detected by determining the use-case specific concepts and examining their specific computational units. When these come from multiple modules (classes) which contribute to multiple use-cases, a candidate aspect is recognized.","PeriodicalId":443491,"journal":{"name":"11th Working Conference on Reverse Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115505558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Binkley","doi":"10.1109/WCRE.2004.26","DOIUrl":"https://doi.org/10.1109/WCRE.2004.26","url":null,"abstract":"Program slicing is a source code extraction technique that can be used to support reverse engineering by automatically extracting executable subprograms that preserve some aspect of the original program's semantics. Although minimal slices are not generally computable, safe approximate algorithms can be used to good effect. However, the precision of such slicing algorithms is a major factor in determining the value of slicing for reverse engineering. Amorphous slicing has been proposed as a way of reducing the size of a slice. Amorphous slices preserve the aspect of semantic interest, but not the syntax that denotes it, making them generally smaller than their syntactically restricted counterparts. Amorphous slicing is suitable for many reverse engineering applications, since reverse engineering typically abandons the existing syntax to facilitate structural improvements. Previous work on amorphous slicing has not attempted to exploit its potential to apply loop-squashing transformations. This paper presents an algorithm for amorphous slicing of loops, which identifies induction variables, transformation rule templates and iteration-determining compile-time expressions. The algorithm uses these to squash certain loops into conditional assignments. The paper also presents an inductive proof of the rule templates and illustrates the application of the algorithm with a detailed example of loop squashing.","PeriodicalId":443491,"journal":{"name":"11th Working Conference on Reverse Engineering","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117066273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solutions are design motifs which software engineers imitate and introduce in the architecture of their program. It is important to identify the design motifs used in a program architecture to understand solved design problems and to make informed changes to the program. The identification of micro-architectures similar to design motifs is difficult because of the large search space, i.e., the many possible combinations of classes. We propose an experimental study of classes playing roles in design motifs using metrics and a machine learning algorithm to fingerprint design motifs roles. Fingerprints are sets of metric values characterising classes playing a given role. We devise fingerprints experimentally using a repository of micro-architectures similar to design motifs. We show that fingerprints help in reducing the search space of micro-architectures similar to design motifs efficiently using the Composite design motif and the JHotDraw framework.","PeriodicalId":443491,"journal":{"name":"11th Working Conference on Reverse Engineering","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125549651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reengineers can easily lose sight of the forest for the trees. There is a need to support a qualitative analysis of the duplicated code.

An informative visualization of the evolution history can help cope with this complexity by highlighting conspicuous evolution events using strong visual cues. We present a scalable visualization technique called evolution spectrographs (ESG). An evolution spectrograph portrays the evolution of a spectrum of components based on a particular property measurement. We describe several special-purpose spectrographs and discuss their use in understanding and supporting software evolution through the case studies of three large software systems (OpenSSH, KOffice and FreeBSD).","PeriodicalId":443491,"journal":{"name":"11th Working Conference on Reverse Engineering","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127340408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a novel software visualisation model for supporting object-oriented software comprehension that is intended to address the shortcomings of existing tools. We discuss the previous work that prompted us to develop this model. An initial model is then presented, based on multiple levels of abstraction, multiple perspectives of the software system, and the integration of statically and dynamically extracted information. We review the evaluation tasks used in our previous work and those from the software visualisation and comprehension literature to produce a refined set of evaluation tasks. We then use these tasks to perform an initial assessment of the proposed model. The refined model is then defined more formally. Finally, a concrete example of the use of the model to generate abstraction hierarchies is discussed. We conclude that a visualisation model incorporating a hierarchy of interrelated abstraction levels, combined with structural and behavioural perspectives of the software, will provide effective support for software comprehension.","PeriodicalId":443491,"journal":{"name":"11th Working Conference on Reverse Engineering","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121141796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially, points out two causes of inappropriately applied patterns from a case study on a large commercial project: developers inexperienced in design patterns and no connection with project requirement. Wrong decisions on the use of design patterns make the program difficult to understand, and refactoring the program to improve the underlying structure, especially without documentation, can be very tricky. To eliminate wrongly applied patterns or document important decisions automatically, design pattern recovery is important for not only the development phase but also the maintenance phase. Many design pattern recovery approaches focus on structural characteristics and do not touch set-up behavior that configures links between participants and precedes pattern behavior. To detect design patterns implemented in program code more precisely and to show their behavior, we analyze program at expression level. Our approach is based on statically approximating run time behavior among pattern participants. For this, a static program analysis technique is used. Many static analysis techniques for object-oriented languages exist mainly for optimizing compiler in program analysis area.","PeriodicalId":443491,"journal":{"name":"11th Working Conference on Reverse Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129535828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
