方法详细资料

first

int first()

Returns the first index of the Sortable.

返回:

The index of the first element.

last

int last()

Returns the last index of the Sortable.

返回:

The index of the last element. If this were an array object this would be (object.length - 1).

fetch

Ordered fetch(int index,
              Ordered reuse)

Fetch the object at the given index.

参数:

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.

返回:

The Ordered object at that index.

swap

void swap(int i,
          int j)

Swaps the elements at the given indicies.

参数:

i - One index.

j - The other index.
