| /** | |
| * This interface should be implemented by classes wishing to | |
| * support of override <code>Object.clone()</code>. The default | |
| * behaviour of <code>clone()</code> performs a shallow copy, but | |
| * subclasses often change this to perform a deep copy. Therefore, | |
| * it is a good idea to document how deep your clone will go. | |
| * If <code>clone()</code> is called on an object which does not | |
| * implement this interface, a <code>CloneNotSupportedException</code> | |
| * will be thrown. | |
| * | |
| * <p>This interface is simply a tagging interface; it carries no | |
| * requirements on methods to implement. However, it is typical for | |
| * a Cloneable class to implement at least <code>equals</code>, | |
| * <code>hashCode</code>, and <code>clone</code>, sometimes | |
| * increasing the accessibility of clone to be public. The typical | |
| * implementation of <code>clone</code> invokes <code>super.clone()</code> | |
| * rather than a constructor, but this is not a requirement. | |
| * | |
| * <p>If an object that implement Cloneable should not be cloned, | |
| * simply override the <code>clone</code> method to throw a | |
| * <code>CloneNotSupportedException</code>. | |
| * | |
| * <p>All array types implement Cloneable, and have a public | |
| * <code>clone</code> method that will never fail with a | |
| * <code>CloneNotSupportedException</code>. | |
