All Implemented Interfaces:

Configurable, Contextualizable

public class InappropriateJavadocBlockTagsOnTypeCheck
extends AbstractJavadocCheck

Checks that Javadoc block tags for type definitions (class, interface, enum, record, annotation) do not contain tags that are semantically invalid for types. Specifically, @return and @throws/@exception tags are meaningless on type declarations since types neither return values nor throw exceptions.

Type declarations (classes, interfaces, enums, records, annotations) do not have return types or throw declarations. Therefore, @return and @throws/@exception Javadoc block tags used in their Javadoc comments are considered inappropriate and should be removed or replaced with proper documentation.

14.1.0
