MongoDB\Driver\Session::advanceOperationTime

    (mongodb >=1.4.0)

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

    说明

    final public 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.

    参数

    operationTime

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

    返回值

    没有返回值。
