The symfinder-2 toolchain
symfinder-2 is an extension of the symfinder toolchain that incorporates the usage relationships to better characterize the visualized density of potential variability implementations, together with an extended visualization relying on entry point classes.
Demos and experiments
All the visualizations for projects presented in “Extending the Identification of Object-Oriented Variability Implementations using Usage Relationships” are available here.
Details about the notion of density are available here.
