  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.
