Interface Sortable
- PageIndex
public interface Sortable
Provides a mechanism to abstract the sort process.
Classes implementing this interface are collections of Ordered objects
that are to be sorted by the Sort class and are
not necessarily Vectors or Arrays of Ordered objects.
Ordered | fetch(int index, Ordered reuse) - Fetch the object at the given index.
|
int | first() - Returns the first index of the Sortable.
|
int | last() - Returns the last index of the Sortable.
|
void | swap(int i, int j) - Swaps the elements at the given indicies.
|
fetch
public Ordered fetch(int index,
Ordered reuse)
Fetch the object at the given index.
index
- The item number to get.reuse
- If this argument is not null, it is an object
acquired from a previous fetch that is no longer needed and
may be returned as the result if it makes mores sense to alter
and return it than to fetch or create a new element. That is, the
reuse object is garbage and may be used to avoid allocating a new
object if that would normally be the strategy.
- The Ordered object at that index.
first
public int first()
Returns the first index of the Sortable.
- The index of the first element.
last
public int last()
Returns the last index of the Sortable.
- The index of the last element.
If this were an array object this would be (object.length - 1).
swap
public void swap(int i,
int j)
Swaps the elements at the given indicies.
i
- One index.j
- The other index.
