In null object pattern, instead of using a null reference to convey the absence of an object, we use an object which implements the expected interface, but leaves the method body empty. The class is part of the package Group: Artifact: kotlin-stdlib Version: 1.3.20. I'd suggest trying to add a Spring annotation which lets you specify a default value, such as ApiParam. This mod works independently of the version of Minecraft used, as it only depends on Fabric Loader being available. To solve this problem, we use the null object design pattern. The default values you're giving are for calls directly from Kotlin, which allows you to omit parameters (and giving explicit names for any later params). This is a mod that enables usage of the Kotlin programming language for Fabric mods. Also, we need to check whether the list is null before using it. The problem with the design of this function is that it doesn't convey whether the List is empty or null or has elements. In Kotlin, when a function does not return any meaningful value, it is declared to return Unit, just like void in Java: fun greet(): Unit Any is a data type in kotlin, any type is super-type of all non-nullable types in kotlin. The Kotlin List.any() function checks if there is at least one element in the list, and returns a boolean value.
