public int getOrder()
Ordered
Normally starting with 0, with Integer.MAX_VALUE
indicating the greatest value. Same order values will result
in arbitrary positions for the affected objects.
Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).
