Field Detail

EMPTY_BIG_LIST

public static final DoubleBigLists.EmptyBigList EMPTY_BIG_LIST

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

Method Detail

shuffle

public static DoubleBigList shuffle(DoubleBigList 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 DoubleBigList singleton(double 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 DoubleBigList 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 DoubleBigList synchronize(DoubleBigList 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.

synchronize

public static DoubleBigList synchronize(DoubleBigList 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.

unmodifiable

public static DoubleBigList unmodifiable(DoubleBigList 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.
