    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  * {@code Object.clone} (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 {@code clone} 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.
