public static JSFinalizationRegistryObject create(JSContext context,
                                                  JSRealm realm,
                                                  JSDynamicObject proto,
                                                  JobCallback cleanupCallback)

createPrototype

public JSDynamicObject createPrototype(JSRealm realm,
                                       JSFunctionObject ctor)

Specified by:

createPrototype in interface JSConstructorFactory

makeInitialShape

public com.oracle.truffle.api.object.Shape makeInitialShape(JSContext context,
                                                            JSDynamicObject prototype)

Overrides:

makeInitialShape in class JSClass

createConstructor

public static JSConstructor createConstructor(JSRealm realm)

getClassName

public com.oracle.truffle.api.strings.TruffleString getClassName()

Specified by:

getClassName in interface JSConstructorFactory

getClassName

public com.oracle.truffle.api.strings.TruffleString getClassName(JSDynamicObject object)

Description copied from class: JSClass

The [[Class]] internal property. For ES5, this is the second part of what Object.prototype.toString.call(myObj) returns, e.g. "[object Array]".

Specified by:

getClassName in class JSClass

Parameters:

object - object to be used

toDisplayStringImpl

public com.oracle.truffle.api.strings.TruffleString toDisplayStringImpl(JSDynamicObject obj,
                                                                        boolean allowSideEffects,
                                                                        ToDisplayStringFormat format,

Description copied from class: JSClass

A more informative toString variant, mainly used for error messages.

Overrides:

toDisplayStringImpl in class JSNonProxy

format - formatting parameters

depth - current nesting depth

isJSFinalizationRegistry

public static boolean isJSFinalizationRegistry(Object obj)

getIntrinsicDefaultProto

public JSDynamicObject getIntrinsicDefaultProto(JSRealm realm)

Description copied from class: JSClass

Allows invokevirtual of this method instead of invokeinterface. Classes overriding this method should implement PrototypeSupplier.

Specified by:

getIntrinsicDefaultProto in interface PrototypeSupplier

Overrides:

getIntrinsicDefaultProto in class JSClass
