Interface IModelComparator

public interface IModelComparator

Implementations 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.
