IUserDefinedAggregation (Atoti Server Java API - 6.0.26)

All Superinterfaces:

IGenericAggregation, IMultiSourceAggregation, Serializable

All Known Implementing Classes:

AUserDefinedAggregation, AUserDefinedVectorAggregation
```
public interface IUserDefinedAggregation
extends IMultiSourceAggregation
```
Interface for user-defined aggregations.
The classes implementing this interface will bind multiple sources to a single destination structure. The destination structures are expected to be adapted for receiving the multiple data.
