MongoDB\Driver\Session::advanceOperationTime — Advances the operation time for this session

説明

final public function MongoDB\Driver\Session::advanceOperationTime(MongoDB\BSON\TimestampInterface $operationTime): void

Advances the operation time for this session. If the operation time is less than or equal to the session's current operation time, this function is a no-op.

By using this method in conjunction with MongoDB\Driver\Session::advanceClusterTime() to copy the operation and cluster times from another session, you can ensure that operations in this session are causally consistent with the last operation in the other session.

パラメータ

operationTime: The operation time is a logical timestamp. Typically, this value will be obtained by calling MongoDB\Driver\Session::getOperationTime() on another session object.

戻り値

値を返しません。

エラー / 例外

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
