public interface Ordered
Interface that can be implemented by objects that should be orderable, for example in a Collection.
The actual order can be interpreted as prioritization, with the first object (with the lowest order value) having the highest priority.

int getOrder()
Normally starting with 0 or 1, with LOWEST_PRECEDENCE
indicating greatest. Same order values will result in arbitrary
positions for the affected objects.
Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).
Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.
