NativeArray

class NativeArray : ScriptableObject

The JavaScript Array.

Small arrays keep their elements in a plain Kotlin array (dense) and only fall back to the slot map once something makes that impossible: a huge index, a getter, a non-array prototype. Upstream also makes every array a java.util.List; that view is not ported.

Functions

Link copied to clipboard
fun associateValue(key: Any, value: Any): Any

Parks value under key, or returns what is already there.

Link copied to clipboard
open fun avoidObjectDetection(): Boolean

True for an object that has to pretend it is undefined, which only NativeWith does.

Link copied to clipboard
fun defineBuiltinProperty(scope: Scriptable, name: String, length: Int, target: SerializableCallable, attributes: Int = DONTENUM, propertyAttributes: Int = DONTENUM or READONLY)

Same as above for a built-in method, which does not get a prototype property.

fun defineProperty(key: Symbol, value: Any?, attributes: Int)

fun defineProperty(cx: Context, key: Symbol, getter: ScriptableObject.LambdaGetterFunction?, setter: ScriptableObject.LambdaSetterFunction?, attributes: Int)
fun defineProperty(cx: Context, name: String, getter: ScriptableObject.LambdaGetterFunction?, setter: ScriptableObject.LambdaSetterFunction?, attributes: Int)

fun defineProperty(name: String, getter: () -> Any??, setter: (Any?) -> Unit?, attributes: Int)

Defines a property whose value comes from a lambda that needs nothing but itself.

fun defineProperty(scope: Scriptable, name: String, length: Int, target: SerializableCallable, attributes: Int = DONTENUM, propertyAttributes: Int = DONTENUM or READONLY)

Defines a method backed by a Kotlin lambda.

fun get(index: Long): Any?
operator fun get(key: Any?): Any?
open override fun get(key: Symbol, start: Scriptable): Any?

open override fun get(index: Int, start: Scriptable): Any?

Gets an indexed property, or NOT_FOUND when there is none.

open override fun get(name: String, start: Scriptable): Any?

Gets a named property, or NOT_FOUND when there is none.

Link copied to clipboard
fun getAssociatedValue(key: Any): Any?

A value another part of the engine parked on this object under key.

open override fun getAttributes(index: Int): Int
open fun getAttributes(sym: Symbol): Int
open fun getAttributes(name: String): Int
Link copied to clipboard
open override fun getDefaultValue(hint: KClass<*>?): Any?

Converts this object to a primitive, guided by hint.

Link copied to clipboard
fun getGetterOrSetter(name: String?, index: Int, scope: Scriptable, isSetter: Boolean): Any?
Link copied to clipboard
open override fun getIds(): Array<Any?>

Every property name of this object alone, ignoring the prototype chain.

open override fun has(key: Symbol, start: Scriptable): Boolean
open override fun has(name: String, start: Scriptable): Boolean

open override fun putConst(name: String, start: Scriptable, value: Any?)
Link copied to clipboard
fun sealObject()

Seals the object, so no property can be added, removed or changed.

fun setAttributes(key: Symbol, attributes: Int)
fun setAttributes(index: Int, attributes: Int)
open fun setAttributes(name: String, attributes: Int)
Link copied to clipboard
fun setExternalArrayData(array: ExternalArrayData?)

Link copied to clipboard
open override fun size(): Int

Part of what java.util.Map needs. NativeObject finishes the job.

Link copied to clipboard
fun toArray(): Array<Any?>

The elements as Kotlin sees them: holes and undefined become null.
