IdFunctionObject

open class IdFunctionObject : BaseFunction

A function identified by a number, which its IdFunctionCall master dispatches on.

Constructors

IdFunctionObject

constructor(idcall: IdFunctionCall, tag: Any?, id: Int, arity: Int)

constructor(idcall: IdFunctionCall, tag: Any?, id: Int, name: String, arity: Int, scope: Scriptable)

Properties

open val allIds: Array<Any?>

Every property, enumerable or not.

open override val arity: Int

What the arity property answers.

open override val className: String

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

declarationScope

open val declarationScope: Scriptable?

The scope this function was declared in.

externalArrayData

val externalArrayData: ExternalArrayData?

externalArrayLength

val externalArrayLength: Any

open override val functionName: String

What the name property answers. Empty for an anonymous function.

open var homeObject: Scriptable?

The object a method was defined on, which super resolves against. Null for a plain function.

open val isExtensible: Boolean

var isSealed: Boolean

open override val length: Int

What the length property answers: how many arguments the function declares.

open override var parentScope: Scriptable?

open override var prototype: Scriptable?

prototypeProperty

open val prototypeProperty: Any?

The prototype property: undefined when unset, null when explicitly set to null.

val tag: Any?

open override val typeOf: String

"function", or "undefined" when avoidObjectDetection says so.

Functions

fun addAsProperty(target: Scriptable)

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.

open override fun call(cx: Context, scope: Scriptable, thisObj: Scriptable?, args: Array<Any?>): Any?

Subclasses override this. The base does nothing.

open override fun construct(cx: Context, scope: Scriptable, args: Array<Any?>): Scriptable

open override fun createObject(cx: Context, scope: Scriptable): Scriptable?

Builds the object that construct passes to call as this. Returning null says that call will make the object itself, and construct then fixes up its scope and prototype.

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.

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

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.

open override fun delete(key: Symbol)

open override fun delete(index: Int)

open override fun delete(name: String)

exportAsScopeProperty

open fun exportAsScopeProperty()

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.

getAssociatedValue

fun getAssociatedValue(key: Any): Any?

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

open fun getAttributes(sym: Symbol): Int

open fun getAttributes(index: Int): Int

open fun getAttributes(name: String): Int

getDefaultValue

open override fun getDefaultValue(hint: KClass<*>?): Any?

Converts this object to a primitive, guided by hint.

getGetterOrSetter

fun getGetterOrSetter(name: String?, index: Int, scope: Scriptable, isSetter: Boolean): Any?

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(index: Int, start: Scriptable): Boolean

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

open override fun hasInstance(instance: Scriptable): Boolean

The instanceof operator for function objects: true when this function's prototype property is somewhere in instance's prototype chain.

fun hasTag(tag: Any?): Boolean

fun initFunction(name: String, scope: Scriptable)

open override fun isConst(name: String): Boolean

open fun isEmpty(): Boolean

markAsConstructor

fun markAsConstructor(prototypeProperty: Scriptable?)

fun methodId(): Int

preventExtensions

open fun preventExtensions(): Boolean

open override fun put(key: Symbol, start: Scriptable, value: Any?)

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

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

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)

setExternalArrayData

fun setExternalArrayData(array: ExternalArrayData?)

setStandardPropertyAttributes

fun setStandardPropertyAttributes(attributes: Int)

open fun size(): Int

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