```
public class AggregateToCollectionOperation
extends java.lang.Object
implements AsyncWriteOperation<java.lang.Void>, WriteOperation<java.lang.Void>

An operation that executes an aggregation that writes its results to a collection (which is what makes this a write operation rather than a read operation).

Since:

3.0
