Constructor Detail

JSTypedArrayObject

protected JSTypedArrayObject(com.oracle.truffle.api.object.Shape shape,
                             TypedArray arrayType,
                             JSArrayBufferObject arrayBuffer,
                             int length,
                             int offset)

Method Detail

typedArrayAccess

public TypedArrayAccess typedArrayAccess()

getArrayType

public TypedArray getArrayType()

create

public static JSTypedArrayObject create(com.oracle.truffle.api.object.Shape shape,
                                        TypedArray arrayType,

getClassName

public String getClassName()

Description copied from class: JSDynamicObject

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

Overrides:

getClassName in class JSClassObject

getBuiltinToStringTag

public String getBuiltinToStringTag()

Description copied from class: JSDynamicObject

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

Overrides:

getBuiltinToStringTag in class JSClassObject

Returns:

"Object" by default
