Implementation

Map<String, dynamic> toJson() {
  final json = <String, dynamic>{};
  json['\$type'] = this.runtimeType.toString().let((type) {
    final regExp = new RegExp(r'([A-Za-z0-9]*)(<.>)?');
    return regExp.firstMatch(type)!.group(1);
  });
  json[r'predicate'] = predicate;

  return json;
