@FunctionalInterface
public interface DiffEvaluator

Interface used to evaluate two models and their normalized differences and return ValidationEvents that are relative to the new model.

For example, a ValidationEvent is emitted when an operation is removed from a service or resource.

Implementations of this interface are found using Java SPI and automatically applied to the detected differences when creating a ModelDiff.
