LineTable

internal object LineTable

Which method owns a source line, read from the class file's LineNumberTable — the descriptor a StackTraceElement does not carry, and the only thing that separates same-named obf overloads.

Only spigot gets here (every other namespace answers owner-free), and there the jar's table is the live one: ByteBuddy advice leaves the target method's lines untouched, and Mixin offsets merged code into a range ABOVE the target's instead of renumbering it — added methods included, a line table being per-method to begin with. A line that matches nothing yields null, so an unknown rewriter costs the obf name we already showed.

Properties

cache

private val cache: ConcurrentHashMap<String, Map<String, String>>

Parsed per owner, and only for one that actually reached an ambiguous frame.

Functions

descAt

fun descAt(internalOwner: String, method: String, line: Int): String?

The descriptor of the method named method whose line table holds line, or null.

key

private fun key(method: String, line: Int): String

parse

private fun parse(internalOwner: String): Map<String, String>

Bridges are skipped: a covariant pair shares one line, so it is the one shape that collides here. Failure caches as empty rather than retrying per frame — an unreadable class stays unreadable.
