ScriptableObject

abstract class ScriptableObject : SlotMapOwner, Scriptable, SymbolScriptable, ConstProperties

The base of every JavaScript object. It keeps the properties, the prototype and the parent scope, and implements the property algorithm the whole language rests on.

Upstream also has a reflection layer here (defineClass, the @JS* annotation scan, and the Method-based defineProperty overloads) that binds Java classes into script. That is LiveConnect and this port does not have it, so those members are gone.

Types

Companion

object Companion

DescriptorInfo

class DescriptorInfo

A property descriptor in the form the engine works with, rather than as a script object. Every field holds Scriptable.NOT_FOUND when the descriptor does not mention it.

LambdaGetterFunction

fun interface LambdaGetterFunction

A getter that gets handed the object it is reading from.

LambdaSetterFunction

fun interface LambdaSetterFunction

A setter that gets handed the object it is writing to.

Properties

allIds

open val allIds: Array<Any?>

Every property, enumerable or not.

className

abstract override val className: String

The class name, as Object.prototype.toString reports it.

externalArrayData

val externalArrayData: ExternalArrayData?

externalArrayLength

val externalArrayLength: Any

isExtensible

open val isExtensible: Boolean

isSealed

var isSealed: Boolean

parentScope

open override var parentScope: Scriptable?

prototype

open override var prototype: Scriptable?

typeOf

open val typeOf: String

What typeof says about this object.

Functions

associateValue

fun associateValue(key: Any, value: Any): Any

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

avoidObjectDetection

open fun avoidObjectDetection(): Boolean

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

defineBuiltinProperty

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.

defineConst

open override fun defineConst(name: String, start: Scriptable)

defineOwnProperties

fun defineOwnProperties(cx: Context, props: ScriptableObject)

defineOwnProperty

fun defineOwnProperty(cx: Context, id: Any?, desc: ScriptableObject): Boolean

open fun defineOwnProperty(cx: Context, id: Any?, desc: ScriptableObject.DescriptorInfo): Boolean

defineProperty

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

fun defineProperty(propertyName: String, value: Any?, attributes: Int)

fun defineProperty(cx: Context, name: String, getter: ScriptableObject.LambdaGetterFunction, 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.
