org.dellroad.stuff.vaadin24.field.FieldComponent<V>

Type Parameters:

V - field value type

All Implemented Interfaces:

Serializable

public class FieldComponent<V>
extends Object
implements Serializable

A combination of a HasValue field and its corresponding Component.

Usually, but not always, these are the same object - for example, with subclasses of AbstractField like ComboBox and TextField.

An example of when they are not the same is when a Grid is used as the visual component for a single select single select field created via Grid.asSingleSelect() or multi-select field created via Grid.asMultiSelect().
