Class LspsProperty

java.lang.Object

com.vaadin.data.util.AbstractProperty<Object>

com.whitestein.lsps.vaadin.ui.LspsProperty

All Implemented Interfaces:

com.vaadin.data.Property<Object>, com.vaadin.data.Property.ReadOnlyStatusChangeNotifier, com.vaadin.data.Property.ValueChangeNotifier, PushableProperty<Object>, Serializable

public class LspsProperty
extends com.vaadin.data.util.AbstractProperty<Object>
implements PushableProperty<Object>

This class embed all necessary logic of accessing and changing LSPS context through references. It also handles the transformation between standard java objects such as set and list but also basic types such as Integer and Double to LSPS type system. This class need to be used whenever accessing LSPS context through references in order to have consistent view of the LSPS context - this class handles things like setting correct values of iterators (ui::Table, ui::Repeater) and usage of the correct view models.
