Java class files may be created by a number of different tools including standard Java compilers, compilers for other languages such as AspectJ, or other tools such as optimizers or obfuscators. There are two kinds of Java decompilers, Javac-specific decompilers that assume that the class file was created by a standard Javac compiler and tool-independent decompilers that can decompile arbitrary class files, independent of the tool that created the class files. Typically Javac-specific decompilers produce more readable code, but they fail to decompile many class files produced by other tools. This paper tackles the problem of how to make a tool-independent decompiler, Dava, produce Java source code that is programmer-friendly. In past work it has been shown that Dava can decompile arbitrary class files, but often the output, although correct, is very different from what a programmer would write and is hard to understand. Furthermore, tools like obfuscators intentionally confuse the class files and this also leads to confusing decompiled source files. Given that Dava already produces correct Java abstract syntax trees (ASTs) for arbitrary class files, we provide a new back-end for Dava. The back-end rewrites the ASTs to semantically equivalent ASTs that correspond to code that is easier for programmers to understand. Our new back-end includes a new AST traversal framework, a set of simple pattern-based transformations, a structure-based data flow analysis framework and a collection of more advanced AST transformations that use flow analysis information. We include several illustrative examples including the use of advanced transformations to clean up obfuscated code","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"87 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132540890","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}

In the recent years many specific rules and patterns for the design of such applications were proposed. These new specific principles of EA design define precise roles (patterns) for classes and methods, and then describe \"good-design\" rules in terms of such roles. Yet, these roles are rarely explicitly documented; therefore, due to their importance for an efficient understanding and assessment of EA design, they must be identified and localized in the source code based on their specificities. In this paper we define a suite of techniques for the identification and location of four such roles, all related to the data source layer of an EA. Using the knowledge about these roles we show how this can improve the accuracy of formerly defined techniques for detecting two well-known design problems (i.e., data class and feature envy), making them more applicable for the usage on enterprise systems. Based on an experimental study conducted on three EAs, we prove the feasibility of the approach, discuss its benefits and touch the issues that need to be addressed in the future","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"307 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133757625","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}

When functions are uncommented, as many are, comprehension is almost exclusively dependent on the identifier names. Assuming that writers of programs want to create quality identifiers (e.g., include relevant domain knowledge) how should they go about it? For example, do the initials of a concept name provide enough information to represent the concept? If not, and a longer identifier is needed, is an abbreviation satisfactory or does the concept need to be captured in an identifier that includes full words? Results from a study designed to investigate these questions are reported. The study involved over 100 programmers who were asked to describe twelve different functions. The functions used three different \"levels\" of identifiers: single letters, abbreviations, and full words. Responses allow the level of comprehension associated with the different levels to be studied. The functions include standard algorithms studied in computer science courses as well as functions extracted from production code. The results show that full word identifiers lead to the best comprehension; however, in many cases, there is no statistical difference between full words and abbreviations","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115842003","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}

Therefore, changes are not related to particular source code entities such as classes or methods but rather to text lines added and/or removed. For analyzing whether some change coupling between source code entities is significant or only minor textual adjustments have been checked in, it is essential to reflect the changes to the source code entities. We have developed an approach for analyzing and classifying change types based on code revisions. We can differentiate between several types of changes on the method or class level and assess their significance in terms of the impact of the change types on other source code entities and whether a change may be functionality-modifying or functionality-preserving. We applied our change taxonomy to a case study and found out that in many cases large numbers of lines added and/or deleted are not accompanied by significant changes but small textual adaptations (such as indentation, etc.). Furthermore, our approach allows us to relate all change couplings to the significance of the identified change types. As a result, change couplings between code entities can be qualified and less relevant couplings can be filtered out","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131618531","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}

One of the main understanding problems is revealed by the so-called \"yo-yo effect\" that appears when a developer or maintainer wants to track a polymorphic method call. At least part of this understanding problem is due to the dual nature of the inheritance relation i.e., the fact that it can he used both as a code and/or as an interface reuse mechanism. Unfortunately, in order to find out the original intention for a particular hierarchy it is not enough to look at the hierarchy itself; rather than that, an in-depth analysis of the hierarchy's clients is required. In this paper we introduce a new metrics-based approach that helps us characterize the extent to which a base class was intended for interface reuse, by analyzing how clients use the interface of that base class. The idea of the approach is to quantify the extent to which clients treat uniformly the instances of the descendants of the base class, when invoking methods belonging to this common interface, We have evaluated our approach on two medium-sized case studies and we have found that the approach does indeed help to characterize the nature of a base class with respect to interface reuse. Additionally, the approach can be used to detect some interesting patterns in the way clients actually use the descendants through the interface of the base class","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129081911","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}
