Package com.mongodb.async.client

Interface AggregateIterable<TResult>

Type Parameters:

TResult - The type of the result.

All Superinterfaces:

MongoIterable<TResult>

Deprecated.

Prefer the Reactive Streams-based asynchronous driver (mongodb-driver-reactivestreams artifactId)

@Deprecated
public interface AggregateIterable<TResult>
extends MongoIterable<TResult>

Iterable for aggregate.

Since:

3.0

Method Summary

Modifier and Type	Method	Description
AggregateIterable<TResult>	allowDiskUse(Boolean allowDiskUse)	Deprecated. Enables writing to temporary files.
AggregateIterable<TResult>	batchSize(int batchSize)	Deprecated. Sets the number of documents to return per batch.
AggregateIterable<TResult>	bypassDocumentValidation(Boolean bypassDocumentValidation)	Deprecated. Sets the bypass document level validation flag.
AggregateIterable<TResult>	collation(Collation collation)	Deprecated. Sets the collation options
AggregateIterable<TResult>	comment(String comment)	Deprecated. Sets the comment to the aggregation.
AggregateIterable<TResult>	hint(Bson hint)	Deprecated. Sets the hint for which index to use.
AggregateIterable<TResult>	maxAwaitTime(long maxAwaitTime, TimeUnit timeUnit)	Deprecated. The maximum amount of time for the server to wait on new documents to satisfy a $changeStream aggregation.
AggregateIterable<TResult>	maxTime(long maxTime, TimeUnit timeUnit)	Deprecated. Sets the maximum execution time on the server for this operation.
void	toCollection(SingleResultCallback<Void> callback)	Deprecated. Aggregates documents according to the specified aggregation pipeline, which must end with a $out stage.
AggregateIterable<TResult>	useCursor(Boolean useCursor)	Deprecated. There is no replacement for this. Applications can assume that the driver will use a cursor for server versions that support it (>= 2.6). The driver will ignore this as of MongoDB 3.6, which does not support inline results for the aggregate command.

maxTime

AggregateIterable<TResult> maxTime(long maxTime,
                                   TimeUnit timeUnit)

Deprecated.

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

Parameters:

maxTime - the max time

timeUnit - the time unit, which may not be null

Returns:

this

maxAwaitTime

AggregateIterable<TResult> maxAwaitTime(long maxAwaitTime,
                                        TimeUnit timeUnit)

Deprecated.

The maximum amount of time for the server to wait on new documents to satisfy a $changeStream aggregation. A zero value will be ignored.

Parameters:

maxAwaitTime - the max await time

timeUnit - the time unit to return the result in

Returns:

the maximum await execution time in the given time unit

useCursor

@Deprecated
AggregateIterable<TResult> useCursor(@Nullable
                                     Boolean useCursor)

Deprecated. There is no replacement for this. Applications can assume that the driver will use a cursor for server versions that support it (>= 2.6). The driver will ignore this as of MongoDB 3.6, which does not support inline results for the aggregate command.

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

Parameters:

useCursor - whether the server should use a cursor to return results

Returns:

this

Deprecated.

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

Parameters:

callback - the callback, which is called when the aggregation completes

Throws:

IllegalStateException - if the pipeline does not end with a $out stage
