Package com.mongodb.client.model.changestream

Class ChangeStreamDocument<TDocument>

java.lang.Object

com.mongodb.client.model.changestream.ChangeStreamDocument<TDocument>

Type Parameters:

TDocument - The type that this collection will encode the fullDocument field into.

public final class ChangeStreamDocument<TDocument>
extends Object

Represents the $changeStream aggregation output document.

Note: this class will not be applicable for all change stream outputs. If using custom pipelines that radically change the change stream result, then an alternative document format should be used.

Since:

3.6
