Mining implementation recipes of framework-provided concepts in dynamic framework API interaction traces

Application developers often apply the Monkey See/Monkey Do rule for framework-based application development, i.e., they use existing applications as a guide to understand how to implement a desired framework-provided concept (e.g., a context menu in an Eclipse view). However, the code that implements the concept of interest might be scattered across and tangled with code implementing other concepts. To address this issue, we introduce a novel framework comprehension technique called FUDA (<u>F</u>ramework API <u>U</u>nderstanding through <u>D</u>ynamic <u>A</u>nalysis). The main idea of this technique is to extract the implementation recipes of a given framework-provided concept from dynamic traces with the help of a dynamic slicing approach integrated with clustering and data mining techniques. In this demonstration, we present the prototype implementation of FUDA as two Eclipse plug-ins, and use them to generate the implementation recipes for a number of concepts in Eclipse views and GEF editors by using only a few example applications.
