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.

Field Summary

Fields

Modifier and Type	Field and Description
static int	HIGHEST_PRECEDENCE Useful constant for the highest precedence value.
static int	LOWEST_PRECEDENCE Useful constant for the lowest precedence value.

Method Summary

Modifier and Type	Method and Description
int	getOrder() Get the order value of this object.

Field Detail

HIGHEST_PRECEDENCE

static final int HIGHEST_PRECEDENCE

Useful constant for the highest precedence value.

See Also:

Integer.MIN_VALUE, Constant Field Values

LOWEST_PRECEDENCE

static final int LOWEST_PRECEDENCE

Useful constant for the lowest precedence value.

See Also:

Integer.MAX_VALUE, Constant Field Values

Method Detail

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
