   ABSTRACT     = {Typical object-oriented (OO) systems implement several 
      functional features that are interwoven into class hierarchies. In 
      the absence of aspect-oriented techniques to develop and compose 
      these features, developers resort to object-oriented design and 
      programming idioms to separate features as well as possible. Given a 
      legacy OO system, discovering existing functional features helps 
      understand the design of the system and extract these features to 
      ease their maintenance and reuse. We want to discover candidate 
      functional features in OO systems. We first define functional 
      features and then discuss the footprints that such features are 
      likely to leave in an OO system. We identify three such footprints: 
      (1) multiple inheritance, (2) delegation, and (3) ad-hoc. We develop 
      a set of algorithms for identifying such footprints in OO code and 
      implemented them for the Java language using Eclipse JDT. In this 
      article, we present the algorithms, and the results of applying the 
      corresponding tools on five open-source systems: FreeMind, 
      JavaWebMail, JHotDraw, JReversePro, and Lucene. Our experimental 
      results show that: (1) the different algorithms can identify 
      interesting and useful candidate functional features in OO systems, 
      (2) they can identify opportunities for refactoring, and (3) they are 
      complementary and could help developers.}
