Reference Kotlinpoet created class in another class.

[DeRealMorgan]

I did not find a way how I can add a parameter in a constructor/cuntion parameter that should be generates by Kotlinpoet.

Either I dont understand the API or there is an obvious limitation or it is simply missing.

Kotlinpoet generates:
class X {}

How can I do this?:
class Y(val x: X) {}

Thanks!

You can use something like ClassName("com.mattel", "Hoverboard") to create a reference to a type that either doesn't exist yet, or isn't available to reference directly inside the code generator.

Here's a fairly self-contained example of using ClassName to reference types by name only:

kotlinpoet/kotlinpoet/src/commonTest/kotlin/com/squareup/kotlinpoet/TypeSpecTest.kt

Lines 1064 to 1083 in 1b9e54b

	@Test fun classImplementsExtendsSameName() {
	val javapoetTaco = ClassName(tacosPackage, "Taco")
	val tacoBellTaco = ClassName("com.taco.bell", "Taco")
	val fishTaco = ClassName("org.fish.taco", "Taco")
	val typeSpec = TypeSpec.classBuilder("Taco")
	.superclass(fishTaco)
	.addSuperinterface(Comparable::class.asClassName().parameterizedBy(javapoetTaco))
	.addSuperinterface(tacoBellTaco)
	.build()
	assertThat(toString(typeSpec)).isEqualTo(
	"""
	|package com.squareup.tacos
	|
	|import kotlin.Comparable
	|
	|public class Taco : org.fish.taco.Taco(), Comparable<Taco>, com.taco.bell.Taco
	|
	""".trimMargin(),
	)
	}
