Interface IUserDefinedAggregation

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.
