Implement this interface if you want to have your own custom methods called during a field update.

Examples:

Shows how to use callback methods during a field update.

 public void fieldUpdatingCallbackTest() throws Exception
 {
     Document doc = new Document();
     DocumentBuilder builder = new DocumentBuilder(doc);

     builder.insertField(" DATE \\@ \"dddd, d MMMM yyyy\" ");

     FieldUpdatingCallback callback = new FieldUpdatingCallback();
     doc.getFieldOptions().setFieldUpdatingCallback(callback);

     doc.updateFields();

     Assert.assertTrue(callback.getFieldUpdatedCalls().contains("Updating John Doe"));
