/**
 * Iterable for change streams.
 *
 * 

Note: the {@link ChangeStreamDocument} class will not be applicable for all change stream outputs. If using custom pipelines that * radically change the result, then the {@link #withDocumentClass(Class)} method can be used to provide an alternative document format.

A null value represents the server default.

*

The default value is an operation time obtained from the server before the change stream was created.

This will allow users to watch collections that have been dropped and recreated * or newly renamed collections without missing any notifications.

* *

Note: The server will report an error if both {@code startAfter} and {@code resumeAfter} are specified.

* * @param startAfter the startAfter resumeToken * @return this * @since 3.11 * @mongodb.server.release 4.2 * @mongodb.driver.manual changeStreams/#change-stream-start-after */ ChangeStreamIterable startAfter(BsonDocument startAfter); }
