Method Details

getShort

public short getShort(int i)

Description copied from interface: ShortList

Returns the element at the specified position in this list.

Specified by:

getShort in interface ShortList

See Also:

List.get(int)

rem

public boolean rem(short k)

Description copied from class: AbstractShortCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation).

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.

rem in interface ShortCollection

Pass null to sort using natural ordering.

This differs from List.sort(java.util.Comparator) in that the results are not assured to be stable, but may be a bit faster.

iterator

public ShortListIterator iterator()

Description copied from interface: ShortCollection

Returns a type-specific iterator on the elements of this collection.

Description copied from interface: ShortList

Removes (hopefully quickly) elements of this type-specific list.

Specified by:

removeElements in interface ShortList

setElements

public void setElements(int index, short[] a, int offset, int length)

Description copied from interface: ShortList

Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by

 
 ListIterator iter = listIterator(index);
 int i = 0;
 while (i < length) {
   iter.next();
   iter.set(a[offset + i++]);
 }
 
 

However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.
