AbstractClassWithOnlyOneDirectInheritor

Reports abstract classes that have precisely one direct inheritor. While such classes 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 abstract class 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.

Example:

abstract class Base {} // will be reported

  class Inheritor extends Base {}
