public interface Ordered
Ordered is an 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.

Note that there is also a priority marker for this interface: PriorityOrdered. Consult the Javadoc for PriorityOrdered for details on how PriorityOrdered objects are ordered relative to plain Ordered objects.

Consult the Javadoc for OrderComparator for details on the sort semantics for non-ordered objects.

  • Method Details

    • getOrder

      int 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:
      the order value
