|
|

When <code>java.io.Serializable</code> is implemented the following three methods are excluded by the rule:
|
||
|
|
* <code>private void writeObject(java.io.ObjectOutputStream out) throws IOException;</code>
|
||
|
|
* <code>private void readObject(java.io.ObjectInputStream in) throws IOException, ClassNotFoundException;</code>
|
||
|
|
* <code>private void readObjectNoData() throws ObjectStreamException;</code>
