Functions

asIterable

@LowLevelApi
abstract override fun asIterable(type: KType): CoroutineMongoAggregateIterable<Document>

asIterable

inline fun <Document : Any> CoroutineMongoAggregationPipeline<Document>.asIterable(): CoroutineMongoAggregateIterable<Document>

Access the data of this pipeline as a MongoIterable.

The methods of MongoIterable are available directly on this type as extension methods, there is no need to convert to a MongoIterable yourself.

abstract override fun <Out : Any> countTo(field: Field<Out, Number>): CoroutineMongoAggregationPipeline<Out>
