cursorToken method

String cursorToken(List<CursorTerm> cursor(F))

Versioned, lossless cursor transport. This is pagination input, not an authorization token. The next query still applies its own WHERE policies.

Implementation

String cursorToken(List<CursorTerm> Function(F) cursor) {
  final terms = cursor(queryFields);
  _validateCursor(terms.map((t) => t.order).toList());
  final payload = {
    'version': 1,
    'table': queryState.source.schema.identity,
    'order': _cursorShape(terms.map((t) => t.order).toList()),
    'values': [
      for (final term in terms) _encodeCursorValue(term.assignedValue),
    ],
  };
  return base64Url.encode(utf8.encode(jsonEncode(payload)));
}
