Interface with a single direct inheritor

Reports interfaces that have precisely one direct inheritor. While such interfaces may offer admirable clarity of design, in memory-constrained or bandwidth-limited environments, they needlessly increase the total footprint of the application. Consider merging the interface with its inheritor.

This inspection is intended for Java ME and other highly resource constrained environments. Applying the results of this inspection without consideration might have negative effects on code clarity and design.
