Class KotlinComponentResolver

java.lang.Object

com.vaadin.copilot.kotlinrewriter.KotlinComponentResolver

public final class KotlinComponentResolver
extends Object

Resolves a selected component to its place in a Kotlin source.

The Kotlin counterpart of ComponentInfoFinder, and the single entry point for both reading and writing. That matters more than it sounds: the panel and an edit must land on the same constructor call, and the hard part of agreeing is the occurrence rule below, which neither caller should be re-deriving.
