Interface LongList

All Superinterfaces:
Collection, Comparable, List, LongCollection
All Known Implementing Classes:
AbstractLongList

public interface LongList
extends List, Comparable, LongCollection

A type-specific List; provides some additional methods that use polymorphism to reduce type juggling.

Note that this type-specific interface extends Comparable: it is expected that implementing classes perform a lexicographical comparison using the standard operator "less then" for primitive types, and the usual compareTo() method for objects.

Besides polymorphic methods, this interfaces specifies methods to copy into an array or remove contiguous sublists. Although the abstract implementation of this interface provides simple, one-by-one implementations of these methods, it is expected that concrete implementation override them with optimised versions.

Method Detail

longListIterator

public LongListIterator longListIterator()
Returns a type-specific list iterator on the list.

The iterator returned by the List.listIterator() method and by this method are identical; however, using this method you can save a type casting.

See Also:
List.listIterator()

longListIterator

public LongListIterator longListIterator(int index)
Returns a type-specific list iterator on the list starting at a given index.

The iterator returned by the List.listIterator() method and by this method are identical; however, using this method you can save a type casting.

See Also:
List.listIterator(int)

longSubList

public LongList longSubList(int from,
                            int to)
See Also:
List.subList(int,int)

size

public void size(int size)
Sets the size of this list.

If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

Parameters:
size - the new size.

getElements

public void getElements(int from,
                        long[] a,
                        int offset,
                        int length)
Copies (hopefully quickly) elements of this type-specific list into the given array.

Parameters:
from - the start index (inclusive).
a - the destination array.
offset - the offset into the destination array where to store the first element copied.
length - the number of elements to be copied.

removeElements

public void removeElements(int from,
                           int to)
Removes (hopefully quickly) elements of this type-specific list.

Parameters:
from - the start index (inclusive).
to - the end index (exclusive).
