| /** |
| * 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<sup><font size="-2">TM</font></sup> |
| * has been added to the <code>java.beans</code> package. |
| * Please see {@link java.beans.XMLEncoder}. |
| * |
| * @see javax.swing.JFormattedTextField |
