Field Details

EMPTY_BIG_LIST

public static final IntBigLists.EmptyBigList EMPTY_BIG_LIST

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

Method Details

shuffle

public static IntBigList shuffle(IntBigList 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.

singleton

public static IntBigList singleton(int 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 IntBigList 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 IntBigList synchronize(IntBigList 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.

• Collections.synchronizedList(List)

synchronize

public static IntBigList synchronize(IntBigList 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 IntBigList unmodifiable(IntBigList 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.

• Collections.unmodifiableList(List)

asBigList

public static IntBigList asBigList(IntList list)

Returns a big list backed by the specified list.

Parameters:

list - a list.

Returns:

a big list backed by the specified list.
