Scattered concerns, design features whose implementations span multiple program units, can pose extra difficulty for developers to locate, understand, modify, and extend. In particular, since successful application frameworks tend to be widely used by many developers, the impact of scattered concerns on framework usability can be especially significant. Ideally, every scattered concern present at...
Aspect oriented programming (AOP) supports the encapsulation of concerns cutting across the logical design of object-oriented software, by introducing aspects as a new unit of code. Code fragments, defined within aspects, such as advice or inter-type declarations, can be composed together with traditional system units, such as classes in OO code, using quantification expressions that specify where...
Facts extracted from source code have been used to support a variety of software engineering activities, ranging from architectural understanding, through detection of design patterns, to program exploration. Several fact extractors have been developed and published in the literature, but most of them extract facts only from individual compilation units. Linking multiple fact-bases is largely overlooked...
Software systems are often written in more than one programming language. During development, programmers need to understand not only the dependencies among code in a particular language, but dependencies that span languages. In this paper, we focus on the problem of scripting languages (such as Perl) and their extension mechanisms to calling functions with a C interface. Our general approach involves...
Software developers often fail to respect the intentions of designers due to missing or ignored documentation of design intent. SCL (Structural Constraint Language) addresses this problem by enabling designers to formalize and confirm compliance with design intent. The designer expresses his intent as constraints on the program model using the SCL language. The SCL conformance checking tool examines...
The Framework Constraint Language (FCL) is a tool for detecting errors in framework usage. FCL is used to specify the syntactic constraints that frameworks impose on the code of framework-based applications. Violations of these constraints are then detected through static analysis. FCL can also be used to encode design rules such as the Law of Demeter and programming guidelines. This paper introduces...
