How to return function in kotlin poet

I'm using KotlinPoet for annotation processing, but I've got an issue. I need return function in generated class, but I'm not sure that KotlinPoet can do it? If you have some experience, please help me.

That I can do: 

fun test(): String = ...

That I need to do 

fun test(): () -> String = ...
Solution

  • Similar to ClassName or TypeName, you can use LambdaTypeName to create a function type with no parameters and String return type:

    val type = LambdaTypeName.get(returnType = String::class.asTypeName())
