DirectiveRegistry

An immutable marker → Directive table — the resolver's only extension point.

Every mutation returns a new registry; Default is never touched by extension. Registration mistakes (bad marker, duplicate, overriding a missing marker) are programmer errors and throw IllegalArgumentException — they are not part of the resolve error contract.

val registry = DirectiveRegistry.Default + ("\$feature" to gate) + vendorPack

Properties

markers

val markers: List<String>

All registered markers, sorted — a determinism guarantee across platforms.

Functions

lookup

fun lookup(marker: String): Directive?

The directive registered under marker, if any.

merge

fun merge(other: DirectiveRegistry, policy: MergePolicy): DirectiveRegistry

A new registry combining this and other; policy settles shared markers.

override

fun override(marker: String, directive: Directive): DirectiveRegistry

A new registry with marker replaced. The marker must already exist.

plus

operator fun plus(entry: <Error class: unknown class><String, Directive>): DirectiveRegistry

register as an operator: DirectiveRegistry.Default + ("${'$'}feature" to gate). Strict like register — a duplicate marker throws; use override to replace.

operator fun plus(other: DirectiveRegistry): DirectiveRegistry

merge under MergePolicy.ERROR as an operator: base + extras. Strict for the same reason plus is — silently picking a side would make which pack won depend on argument order. Call merge directly to choose another policy.

operator fun plus(entries: Iterable<<Error class: unknown class><String, Directive>>): DirectiveRegistry

fun register(marker: String, directive: Directive): DirectiveRegistry

A new registry with directive under marker. The marker must start with $ and be unused; use override to replace an existing one.
