Inspectopedia 2024.3 Help

Class may extend a commonly used base class

Reports classes or interfaces that can be replaced with an implementation or extension of a more specific commonly used class or interface.

For this inspection to work, a superclass needs to be in project source files and the project needs to use the IntelliJ IDEA build system.

Example:

class MyInheritor implements A {} // B suggested on the A reference interface A {} abstract class B implements A {} abstract class C1 extends B {} abstract class C2 extends B {} abstract class C3 extends B {} abstract class C4 extends B {} abstract class C5 extends B {}
