(mongodb >=1.5.0)

参数
此函数没有参数。
返回值
没有返回值。
错误／异常
- Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
- 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).
