For an example look in "our"
javax.management.modelmbean.DescriptorSupport
private void readObject(ObjectInputStream ois)
throws IOException, ClassNotFoundException
{
ObjectInputStream.GetField getField = ois.readFields();
HashMap serMap = (HashMap) getField.get("descriptor", null);
if (serMap == null)
throw new StreamCorruptedException("Null descriptor?");
// replace the keys with FieldName objects
fieldMap = Collections.synchronizedMap(new HashMap());
Iterator it = serMap.entrySet().iterator();
while (it.hasNext())
{
Map.Entry entry = (Map.Entry) it.next();
FieldName key = new FieldName((String)entry.getKey());
fieldMap.put(key, entry.getValue());
}
}
