V - base type of all values in the column identified by this instance.

All Implemented Interfaces:

Serializable, CheckedContainer<V>

Enclosing class:

TableColumn<V>

private static final class TableColumn.Constant<V>
extends TableColumn<V>
implements Serializable

Implementation of TableColumn for the predefined constants. This implementation differs resource bundle loading until first needed, and resolves deserialized instances to the singleton instances.
