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.
