kotlinlang

In Java, it is possible to declare an object of a type `Something&lt;?&gt;` to say that the generic is ignored. Is there any similar syntax in Kotlin? If so, where can I find documentation that explains how to use it?

The simple answer is <https://kotlinlang.org/docs/reference/generics.html|it depends>

• `Something&lt;*&gt;` 
• `Something&lt;Any&gt;` 
• `Something&lt;Unit&gt;`
• `Something&lt;Nothing&gt;` 
 Depends on what ignore means I guess.

The wildcard `*` means `out Any?` for covariant type parameters (when _getting_ a value, you can safely assign it to a variable of type `Any?`) or `in Nothing` for contravariant type parameters (there is no safe way to _set_ a value safely).

If you are planning to _never_ call any methods that use a type-parameter on an interface having that type parameter, use `*` for that type parameter fro the declaration of your variable/parameter/property.
