0N/A/**
0N/A * A composite Border class used to compose two Border objects
0N/A * into a single border by nesting an inside Border object within
0N/A * the insets of an outside Border object.
0N/A *
0N/A * For example, this class may be used to add blank margin space
0N/A * to a component with an existing decorative border:
0N/A * <p>
0N/A * <code><pre>
0N/A * Border border = comp.getBorder();
0N/A * Border margin = new EmptyBorder(10,10,10,10);
0N/A * comp.setBorder(new CompoundBorder(border, margin));
0N/A * </pre></code>
0N/A * <p>
0N/A * <strong>Warning:</strong>
0N/A * Serialized objects of this class will not be compatible with
0N/A * future Swing releases. The current serialization support is
0N/A * appropriate for short term storage or RMI between applications running
0N/A * the same version of Swing. As of 1.4, support for long term storage
0N/A * of all JavaBeans<sup><font size="-2">TM</font></sup>
0N/A * has been added to the <code>java.beans</code> package.
0N/A * Please see {@link java.beans.XMLEncoder}.
