toXPathString function

String toXPathString(Object value)

XPath string().

Numbers print as integers when within 1e-12 of (int) d; because Java's cast saturates at 2^31, larger whole numbers print in Java notation (string(10000000000) is 1.0E10).

Implementation

String toXPathString(Object value) {
  final o = unpack(value);
  return switch (o) {
    bool() => o ? 'true' : 'false',
    double() => _numberToString(o),
    String() => o,
    DateTime() => date_utils.formatDate(o, DateFormatStyle.iso8601),
    ExprDataType() => o.toString(),
    _ => throw XPathTypeMismatchException('converting to string'),
  };
}
