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.
