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.

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
