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