public int getOrder()

Implements org.springframework.core.Ordered.getOrder.

Doc from org.springframework.core.Ordered.getOrder.

Get the order value of this object.

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.

Returns:int

the order value
