C++ (Cpp) JSDataView::byteOffset Examples

Example #1

EncodedJSValue JSC_HOST_CALL dataViewProtoGetterByteOffset(ExecState* exec)
{
    VM& vm = exec->vm();
    auto scope = DECLARE_THROW_SCOPE(vm);

    JSDataView* view = jsDynamicCast<JSDataView*>(exec->thisValue());
    if (!view)
        return throwVMTypeError(exec, scope, "DataView.prototype.buffer expects |this| to be a DataView object");

    return JSValue::encode(jsNumber(view->byteOffset()));
}
