public void setOrder(int order)
The default value is Ordered.LOWEST_PRECEDENCE
, meaning non-ordered.
Ordered.getOrder()
public int getOrder()
Ordered
Higher values are interpreted as lower priority. As a consequence,
the object with the lowest value has the highest priority (somewhat
analogous to Servlet load-on-startup
values).
Same order values will result in arbitrary sort positions for the affected objects.
