ArCode: A Tool for Supporting Comprehension and Implementation of Architectural Concerns

Integrated development environments (IDE) play an important role in supporting developers during program comprehension and completion. Many of these supportive features focus on low-level programming and debugging activities. Unfortunately, there is less support in understanding and implementing architectural concerns in the form of patterns, tactics and/or other concerns. In this paper we present ArCode, a tool designed as a plugin for a popular IDE, IntelliJ IDEA. ArCode is able to learn correct ways of using frameworks' API to implement architectural concerns such as Authentication and Authorization from two sources, sample programs that practice the framework, and the byte code of that framework. Analyzing a program under development, this tool is able to find deviations from correct implementation and provide fix recommendations alongside with graphical demonstrations to better communicate the recommendations with the developers. We showcase how programmers can benefit from ArCode by providing an example of API misuse detection and API recommendation for a popular Java framework, Java Authentication and Authorization (JAAS) security framework.
