How to return function in kotlin poet

Question

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 = ...

与ClassName或TypeName相似，可以使用LambdaTypeName创建不带参数且String返回类型的函数类型：

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