JniActual

@Target(allowedTargets = [AnnotationTarget.FUNCTION])

annotation class JniActual(val className: String, val methodName: String = "")(source)

Indicates that a function (public or internal) is the actual implementation of a function expected to be provided through JNI.

Should be applied to functions that:

are top-level
have no context parameter or a single one of type JniEnv
have a receiver of type JObject or JClass or don't have any receiver.

A function may also declare a native-memory placement context parameter: AutofreeScope, NativePlacement, ArenaBase or MemScope. So the body can allocate through the placement.

Properties

className

val className: String

The fully qualified name of the class. E.g., "com.example.NativeHelper"

methodName

val methodName: String

The name of the method in the class, no mater static or instance. E.g., "nativeComputation". Optional: may be omitted if the name is the same as the marked function has.
