TopLevel

A global scope that remembers the original built-in constructors.

The spec says most internal construction has to use the original prototype, but the global constructors are writable and deletable, so a script can replace them. Caching them here keeps internal work pointing at the real ones.

Context.initStandardObjects fills this cache when the scope is a TopLevel. A scope that inherits its globals from a prototype instead has to call cacheBuiltins itself.

Constructors

TopLevel

constructor()

Types

Builtins

enum Builtins : Enum<TopLevel.Builtins>

The built-in types worth caching.

Companion

object Companion

Properties

allIds

open val allIds: Array<Any?>

Every property, enumerable or not.

className

open 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.

cacheBuiltins

fun cacheBuiltins(scope: Scriptable, sealed: Boolean)

Takes a copy of the built-in constructors so a script cannot change what the engine itself uses. ScriptRuntime.initStandardObjects calls this when the scope is a TopLevel.

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.
