### パラメータ

この関数にはパラメータはありません。

### 返り値

値を返しません。

### エラー / 例外

- 引数のパースに失敗した場合に MongoDB\Driver\Exception\InvalidArgumentException をスローします。
- Throws MongoDB\Driver\Exception\CommandException if the server could not commit the transaction (e.g. due to conflicts, network issues). In case the exception's MongoDB\Driver\Exception\CommandException::getResultDocument() has a "errorLabels" element, and this array contains a "TransientTransactionError" or "UnUnknownTransactionCommitResult" value, it is safe to re-try the whole transaction. In newer versions of the driver, MongoDB\Driver\Exception\RuntimeException::hasErrorLabel() should be used to test for this situation instead.
- Throws MongoDB\Driver\Exception\RuntimeException if the transaction could not be commited (e.g. a transaction was not started).
