| 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. |
