Highly Configurable and Extensible Code Clone Detection

Code clone detection is an enabling technology for plenty of applications, each having different requirements to a clone detector. In this paper we present a generic pipeline model of the code clone detection process. Based on this model we developed the JCCD code clone detection API for implementing custom clone detectors. By combining and parameterizing predefined API components as well as by adding new components, the pipeline model does not only facilitate to build new clone detectors, but also to parallelize the detection process.
