- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface IModelComparator extends IClusterableImplementations of this interface compare model object. The component is given so that a developer can choose what the previous object is The default implementation for form components is just component.getModelObject(); But developers can choose to keep the last rendered value for that component and compare this value with the newObject. So that it doesn't overwrite values for an object that was changed by another session if the current session didn't touch that specific value.
