Annotation Type DeveloperApi

@Retention(value=RUNTIME)
@Target(value={TYPE,FIELD,METHOD,PARAMETER,CONSTRUCTOR,LOCAL_VARIABLE,PACKAGE})
public @interface DeveloperApi

A lower-level, unstable API intended for developers. Developer API's might change or be removed in minor versions of Spark. NOTE: If there exists a Scaladoc comment that immediately precedes this annotation, the first line of the comment must be ":: DeveloperApi ::" with no trailing blank line. This is because of the known issue that Scaladoc displays only either the annotation or the comment, whichever comes first.
