- * Adapt an element in a collection value model to a property value model.

- * contains the value: If the collection model contains the value,
- * the property model's value is <em>that</em> element; otherwise, the property
- * model's value is <code>null</code>. A {@link #predicate} is used to determine
- * whether the collection model contains the relevant value.
- * <p>
- * This is useful for a client (e.g. a UI widget) that is longer-living than its
- * underlying model. Obviously, the client must be prepared to handle a value of
- * <code>null</code>.
