/**
 * An implementation of
 * <code>JFormattedTextField.AbstractFormatterFactory</code>.
 * <code>DefaultFormatterFactory</code> allows specifying a number of
 * different <code>JFormattedTextField.AbstractFormatter</code>s that are to
 * be used.
 * The most important one is the default one
 * (<code>setDefaultFormatter</code>). The default formatter will be used
 * if a more specific formatter could not be found. The following process
 * is used to determine the appropriate formatter to use.
 * <ol>
 *   <li>Is the passed in value null? Use the null formatter.
 *   <li>Does the <code>JFormattedTextField</code> have focus? Use the edit
 *       formatter.
 *   <li>Otherwise, use the display formatter.
 *   <li>If a non-null <code>AbstractFormatter</code> has not been found, use
 *       the default formatter.
 * </ol>
 * <p>
 * The following code shows how to configure a
 * <code>JFormattedTextField</code> with two
 * <code>JFormattedTextField.AbstractFormatter</code>s, one for display and
 * one for editing.
 * <pre>
 * JFormattedTextField.AbstractFormatter editFormatter = ...;
 * JFormattedTextField.AbstractFormatter displayFormatter = ...;
 * DefaultFormatterFactory factory = new DefaultFormatterFactory(
 *                 displayFormatter, displayFormatter, editFormatter);
 * JFormattedTextField tf = new JFormattedTextField(factory);
 * </pre>
 * <p>
 * <strong>Warning:</strong>
 * Serialized objects of this class will not be compatible with
 * future Swing releases. The current serialization support is
 * appropriate for short term storage or RMI between applications running
 * the same version of Swing.  As of 1.4, support for long term storage
 * of all JavaBeans&trade;
 * has been added to the <code>java.beans</code> package.
 * Please see {@link java.beans.XMLEncoder}.
 *
 * @see javax.swing.JFormattedTextField

 * @since 1.4
