Leveraging Program Comprehension with Concern-oriented Source Code Projections

In this paper we briefly introduce our concern-oriented source code projections that enable looking at same source code in multiple different ways. The objective of this paper is to discuss projection creation process in detail and to explain benefits of using projections to aid program comprehension. We achieve this objective by showing a case study that illustrates using projections on examples. Presented case study was done using our prototypical tool that is implemented as a plugin for NetBeans IDE. We briefly introduce the tool and present an experiment that we have conducted with a group of students at our university. The results of the experiment indicate that projections have positive effect on program comprehension.
