接口 Ordered

所有已知子接口:

PriorityOrdered

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. Order values expressed by PriorityOrdered objects always apply before same order values expressed by plain Ordered objects.

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

方法详细资料

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.
