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 the list of annotations that allow missed documentation. Only short names are allowed, e.g. Generated. 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 {}

    Example that allows missing comments for classes annotated with @SpringBootApplication and @Configuration: 

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

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

    Use following configuration: 

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