  3. def bypassDocumentValidation(bypassDocumentValidation: Boolean): AggregateObservable[TResult]

    Sets the bypass document level validation flag.

    Sets the bypass document level validation flag.

    Note:: This only applies when an $out stage is specified.

    Aggregation

    bypassDocumentValidation

    If true, allows the write to opt-out of document level validation.

    returns

    this

  5. def comment(comment: String): AggregateObservable[TResult]

    Sets the comment to the aggregation.

    Sets the comment to the aggregation. A null value means no comment is set.

    comment

    the comment

    returns

    this

    Since

    2.2

    Note

    Requires MongoDB 3.6 or greater

  6. def hint(hint: Bson): AggregateObservable[TResult]

    Sets the hint for which index to use.

    Sets the hint for which index to use. A null value means no hint is set.

    hint

    the hint

    returns

    this

  7. def maxAwaitTime(duration: Duration): AggregateObservable[TResult]

    Sets the maximum await execution time on the server for this operation.

    Sets the maximum await execution time on the server for this operation.

    Max Time

    duration

  10. def subscribe(observer: Observer[_ >: TResult]): Unit

    Request Observable to start streaming data.

    Request Observable to start streaming data.

    This is a "factory method" and can be called multiple times, each time starting a new Subscription. Each Subscription will work for only a single Observer.

    If the Observable rejects the subscription attempt or otherwise fails it will signal the error via Observer.onError.

    observer

    the Observer that will consume signals from this Observable

    AggregateObservable → Observable
  11. def subscribe(observer: com.mongodb.async.client.Observer[_ >: TResult]): Unit

    Handles the automatic boxing of a Java Observable so it conforms to the interface.

    Handles the automatic boxing of a Java Observable so it conforms to the interface.

    observer

    the Observer that will consume signals from this Observable

    Definition Classes
    Observable → Observable
    Note

    Users should not have to implement this method but rather use the Scala Observable.

  12. def toCollection(): Observable[Completed]

    Aggregates documents according to the specified aggregation pipeline, which must end with a $out stage.

    Aggregates documents according to the specified aggregation pipeline, which must end with a $out stage.

    Aggregation

    returns

    a Observable with a single element indicating when the operation has completed

Deprecated Value Members

  1. def useCursor(useCursor: Boolean): AggregateObservable[TResult]

    Sets whether the server should use a cursor to return results.

    Sets whether the server should use a cursor to return results.

    Aggregation
