Field Detail

EMPTY_LIST

public static final ShortLists.EmptyList EMPTY_LIST

An empty list (immutable). It is serializable and cloneable.

The class of this objects represent an abstract empty list that is a sublist of any type of list. Thus, EMPTY_LIST may be assigned to a variable of any (sorted) type-specific list.

Method Detail

shuffle

public static ShortList shuffle(ShortList l,
                Random random)

Shuffles the specified list using the specified pseudorandom number generator.

Parameters:

l - the list to be shuffled.

random - a pseudorandom number generator (please use a XorShift* generator).

Returns:

l.

singleton

public static ShortList singleton(short element)

Returns a type-specific immutable list containing only the specified element. The returned list is serializable and cloneable.

Parameters:

element - the only element of the returned list.

Returns:

a type-specific immutable list containing just element.

singleton

public static ShortList singleton(Object element)

Returns a type-specific immutable list containing only the specified element. The returned list is serializable and cloneable.

Parameters:

element - the only element of the returned list.

Returns:

a type-specific immutable list containing just element.

synchronize

public static ShortList synchronize(ShortList l)

Returns a synchronized type-specific list backed by the given type-specific list.

Parameters:

l - the list to be wrapped in a synchronized list.

Returns:

a synchronized view of the specified list.

Collections.synchronizedList(List)

synchronize

public static ShortList synchronize(ShortList l,
                    Object sync)

Returns a synchronized type-specific list backed by the given type-specific list, using an assigned object to synchronize.

Parameters:

l - the list to be wrapped in a synchronized list.

sync - an object that will be used to synchronize the access to the list.

Returns:

a synchronized view of the specified list.

Collections.synchronizedList(List)

unmodifiable

public static ShortList unmodifiable(ShortList l)

Returns an unmodifiable type-specific list backed by the given type-specific list.

Parameters:

l - the list to be wrapped in an unmodifiable list.

Returns:

an unmodifiable view of the specified list.
