Class ComponentWithValue.ValueProperty<T>

java.lang.Object

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

com.whitestein.lsps.vaadin.forms.ComponentWithValue.ValueProperty<T>

Type Parameters:

T -

All Implemented Interfaces:

com.vaadin.data.Property<T>, com.vaadin.data.Property.ReadOnlyStatusChangeNotifier, com.vaadin.data.Property.ValueChangeNotifier, Serializable

Enclosing class:

ComponentWithValue<T>

public static class ComponentWithValue.ValueProperty<T>
extends com.vaadin.data.util.AbstractProperty<T>

Wraps the forms::Binding LSPS record and adapts it to the Vaadin Property interface. Reading this Vaadin property will retrieve the value of forms::Binding.get() (cached, read below), writing to this Vaadin property will in turn call the forms::Binding.set() method.

Note that the forms::Binding.get() is called immediately when this object is constructed, and is cached afterwards. TODO why?
