MetaCapture

internal class MetaCapture : AnnotationVisitor

Captures a @kotlin.Metadata annotation during an ASM read, and re-emits it — verbatim, or as a rewritten replacement. Stores ONLY the fields the original actually carried, which is what makes a verbatim re-emit add nothing: a lambda class (k=3) carries no d1, and an empty one reads back as a deserializable proto, NPEing readFunctionDataFrom deep inside the inliner. Primitive arrays (mv/bv) arrive as one value; string arrays (d1/d2) arrive element-by-element via a nested visitArray visitor.

Properties

protected val api: Int

protected var av: AnnotationVisitor?

open val delegate: AnnotationVisitor?

private val fields: LinkedHashMap<String, Any?>

Field name (@Metadata's JvmNames: k/mv/bv/d1/d2/xs/pn/xi) -> value; string arrays held as List.

Functions

fun emit(av: AnnotationVisitor, replacement: Map<String, Any?>?)

Emit replacement (a rewrite) or the captured fields verbatim into av.

fun fieldNames(): Set<String>

Which fields the original annotation actually carried — the set a rewrite must reproduce one-for-one.

fun original(name: String): Any?

What a rewrite cannot reproduce, read off the original — see fieldOr.

private fun strings(n: String): Array<String>?

fun toMetadata(): Metadata

The captured annotation as a real Metadata, for kotlin-metadata to read.
