This is where things become… complicated. Kotlin’s “internal” Modifier as Seen From Java What visibility modifiers does Kotlin have, What is the visibility of an internal modifier, How many classes can you put in single. In the above example, the Foo class will only be accessible from a particular Maven module (or equivalents for other build tools). Introducing Kotlin’s “internal” Modifierįor those that do not know, internal modifier restricts the visibility of an element to a particular module: internal class Foo So… I wonder how Kotlin’s internal classes are represented in and seen from pure Java then? It’s not surprising since it was built on top of the JVM and a lot of its syntax sugar is actually implemented by using standard Java features!įor example, if we define an extension method on a standard String class, underneath it’s just a standard static method: fun String.asHelloWorld() : String = 'Hello $this' Visibility.PACKAGE, // Java-specific package-private i don't know if keep the issue open or not because my solution goes through migrating to kotlin dsl and groovy code still not working.Kotlin features almost excellent compatibility with Java. Visibility.INTERNAL, // Kotlin-specific internal modifier Visibility modifier keywords restricts the use. Visibility.PROTECTED, // Same for both Kotlin and Java Access modifiers or visibility modifiers are used to define the scope of a class, function, field, interface etc. This means that in order to use the internal interface you still need to expose the functions within them, so I do not understand the use of this feature. While the interface itself is internal, it still forces the implementations of its methods to be public.

Visibility.PRIVATE, // Same for both Kotlin and Java I do not understand when I would an internal interface as they currently exist in Kotlin. Visibility.PUBLIC, // Same for both Kotlin and Java If set by user, overrides includeNonPublic. A set of visibility modifiers that should be documented , Kindly let us know when would the documentation be available for groovy or if you can post a sample groovy implementation here, that would be really helpful But only when I add documented visibilities, it is not working and I get the same error. This dokka bit is working for me in groovy when the documented visibilities is commented out. Hi and, I am facing the same issue right now.ĭ, // Same for both Kotlin and Javaĭ, // Same for both Kotlin and Javaĭ, // Same for both Kotlin and Javaĭ, // Kotlin-specific internal modifierĭ // Java-specific package-private visibility
