Class MissingJavadocTypeCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable

    public class MissingJavadocTypeCheck
    extends AbstractCheck

    Checks for missing Javadoc comments for class, enum, interface, and annotation interface definitions. The scope to verify is specified using the Scope class and defaults to Scope.PUBLIC. To verify another scope, set property scope to one of the Scope constants.

    • Property scope - specify the visibility scope where Javadoc comments are checked. Type is com.puppycrawl.tools.checkstyle.api.Scope. Default value is public.
    • Property excludeScope - specify the visibility scope where Javadoc comments are not checked. Type is com.puppycrawl.tools.checkstyle.api.Scope. Default value is null.
    • Property skipAnnotations - specify annotations that allow missed documentation. If annotation is present in target sources in multiple forms of qualified name, all forms should be listed in this property. Type is java.lang.String[]. Default value is Generated.
    • Property tokens - tokens to check Type is java.lang.String[]. Validation type is tokenSet. Default value is: INTERFACE_DEF, CLASS_DEF, ENUM_DEF, ANNOTATION_DEF, RECORD_DEF.

    To configure the default check to make sure all public class, enum, interface, and annotation interface, definitions have javadocs:

     <module name="MissingJavadocType"/>
     

    Example:

     public class PublicClass {} // violation
     private class PublicClass {}
     protected class PublicClass {}
     class PackagePrivateClass {}
     

    To configure the check for private scope:

     <module name="MissingJavadocType">
       <property name="scope" value="private"/>
     </module>
     

    Example:

     public class PublicClass {} // violation
     private class PublicClass {} // violation
     protected class PublicClass {} // violation
     class PackagePrivateClass {} // violation
     

    To configure the check for private classes only:

     <module name="MissingJavadocType">
       <property name="scope" value="private"/>
       <property name="excludeScope" value="package"/>
     </module>
     

    Example:

     public class PublicClass {}
     private class PublicClass {} // violation
     protected class PublicClass {}
     class PackagePrivateClass {}
     

    To configure a check that allows missing comments for classes annotated with @SpringBootApplication and @Configuration:

     <module name="MissingJavadocType">
       <property name="skipAnnotations" value="SpringBootApplication,Configuration"/>
     </module>
     

    Example:

     @SpringBootApplication // no violations about missing comment on class
     public class Application {}
    
     @Configuration // no violations about missing comment on class
     class DatabaseConfiguration {}
     

    To configure a check that allows missing comments for classes annotated with @Annotation and @MyClass.Annotation:

     <module name="MissingJavadocType">
       <property name="skipAnnotations" value="Annotation,MyClass.Annotation"/>
     </module>
     

    Example:

     @Annotation // ok
     class Class1 {}
    
     @MyClass.Annotation // ok
     class Class2 {}
    
     @com.mycompany.MyClass.Annotation // violation, as this form is missed in config
     class Class3 {}
