29   * A class implements the <code>Cloneable</code> interface to
30   * indicate to the {@link java.lang.Object#clone()} method that it
31   * is legal for that method to make a
32   * field-for-field copy of instances of that class.
33   * <p>
34   * Invoking Object's clone method on an instance that does not implement the
35   * <code>Cloneable</code> interface results in the exception
36   * <code>CloneNotSupportedException</code> being thrown.
37   * <p>
38   * By convention, classes that implement this interface should override
39   * <tt>Object.clone</tt> (which is protected) with a public method.
40   * See {@link java.lang.Object#clone()} for details on overriding this
41   * method.
42   * <p>
43   * Note that this interface does <i>not</i> contain the <tt>clone</tt> method.
44   * Therefore, it is not possible to clone an object merely by virtue of the
45   * fact that it implements this interface.  Even if the clone method is invoked
46   * reflectively, there is no guarantee that it will succeed.
