Field Detail

EMPTY_BIG_LIST

public static final ShortBigLists.EmptyBigList EMPTY_BIG_LIST

An empty big 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_BIG_LIST may be assigned to a variable of any (sorted) type-specific list.

Method Detail

shuffle

public static ShortBigList shuffle(ShortBigList l,
                   Random random)

Shuffles the specified big list using the specified pseudorandom number generator.

Parameters:

l - the big list to be shuffled.

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

Returns:

l.

singleton

public static ShortBigList singleton(short element)

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

Parameters:

element - the only element of the returned big list.

Returns:

a type-specific immutable big list containing just element.

singleton

public static ShortBigList singleton(Object element)

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

Parameters:

element - the only element of the returned big list.

Returns:

a type-specific immutable big list containing just element.

synchronize

public static ShortBigList synchronize(ShortBigList l)

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

Parameters:

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

Returns:

a synchronized view of the specified big list.

See Also:

Collections.synchronizedList(List)

synchronize

public static ShortBigList synchronize(ShortBigList l,
                       Object sync)

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

Parameters:

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

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

Returns:

a synchronized view of the specified big list.

See Also:

Collections.synchronizedList(List)

unmodifiable

public static ShortBigList unmodifiable(ShortBigList l)

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

Parameters:

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

Returns:

an unmodifiable view of the specified big list.

See Also:

Collections.unmodifiableList(List)

asBigList

public static ShortBigList asBigList(ShortList list)

Returns a big list backed by the specified list.

Parameters:

list - a list.

Returns:

a big list backed by the specified list.
