Field Details

EMPTY_BIG_LIST

public static final ReferenceBigLists.EmptyBigList EMPTY_BIG_LIST

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

Method Details

shuffle

public static <K> ReferenceBigList<K> shuffle(ReferenceBigList<K> 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.

Returns:

l.

emptyList

public static <K> ReferenceBigList<K> emptyList()

Returns an empty big list (immutable). It is serializable and cloneable.

This method provides a typesafe access to EMPTY_BIG_LIST.

Returns:

an empty big list (immutable).

singleton

public static <K> ReferenceBigList<K> singleton(K 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 <K> ReferenceBigList<K> synchronize(ReferenceBigList<K> 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 <K> ReferenceBigList<K> synchronize(ReferenceBigList<K> 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 <K> ReferenceBigList<K> unmodifiable(ReferenceBigList<? extends K> 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 <K> ReferenceBigList<K> asBigList(ReferenceList<K> list)

Returns a big list backed by the specified list.

Parameters:

list - a list.

Returns:

a big list backed by the specified list.
