CreateProcedure.fromJson constructor

CreateProcedure.fromJson(Object? json_)

Returns a new instance from a JSON value. May throw if the value does not have the expected structure.

Implementation

factory CreateProcedure.fromJson(Object? json_) {
  final json = json_ is Map
      ? _spec.fields.map((f) => json_[f.label]).toList(growable: false)
      : json_;
  return switch (json) {
    [final orAlter, final name, final params, final body] ||
    (final orAlter, final name, final params, final body) =>
      CreateProcedure(
        orAlter: orAlter! as bool,
        name: (name! as Iterable).map(Ident.fromJson).toList(),
        params: Option.fromJson(
                params,
                (some) =>
                    (some! as Iterable).map(ProcedureParam.fromJson).toList())
            .value,
        body: (body! as Iterable).map(SqlAstRef.fromJson).toList(),
      ),
    _ => throw Exception('Invalid JSON $json_')
  };
}
