Interface TransformStatistics

All Known Implementing Classes:
SimpleTransform
public interface TransformStatistics
An interface for the statistics that need to be collected for a specific Transformation on a single feature.

TransformStatistics are purely a runtime collection, they should not be persisted, nor can be directly constructed.
