/**
 * Get the string representation of the default value of the field.
 * 
 * @return the default value, or {@code null} if there is no default value
 */
public String defaultValueAsString() {
  Object defaultValue = defaultValue();
  return defaultValue != null ? defaultValue.toString() : null;
}
