Package org.sormula.operation.cascade.lazy Description

Implementation of lazy loading. When SelectCascade.lazy() true, for a field, the field is not selected when the source row is selected. The lazy select field can be selected at a later time by using the method AbstractLazySelector.checkLazySelects(String) in one of the subclasses SimpleLazySelector, DurableLazySelector, your own subclass, or your own implementation of LazySelectable.
