                                    JSDynamicObject proto,
                                    Number value)

valueOf

public static Number valueOf(JSDynamicObject obj)

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

fillConstructor

public void fillConstructor(JSRealm realm,
                            JSDynamicObject constructor)

Specified by:

fillConstructor in interface JSConstructorFactory

isJSNumber

public static boolean isJSNumber(Object obj)

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

getBuiltinToStringTag

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

Description copied from class: JSClass

Returns builtinTag from step 14 of ES6+ 19.1.3.6. By default returns "Object".

Overrides:

getBuiltinToStringTag in class JSNonProxy

Parameters:

object - object to be used

Returns:

"Object" by default

JSClass.defaultToString(JSDynamicObject)

toDisplayStringImpl

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

                                                                        int depth)

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

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
