Field Details

EMPTY_LIST

public static final FloatLists.EmptyList EMPTY_LIST

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

Method Details

shuffle

public static FloatList shuffle(FloatList 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.

Returns:

l.

emptyList

public static FloatList emptyList()

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

This method provides a typesafe access to EMPTY_LIST.

Returns:

an empty list (immutable).

singleton

public static FloatList singleton(float 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 FloatList 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 FloatList synchronize(FloatList 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.

See Also:

• Collections.synchronizedList(List)

synchronize

public static FloatList synchronize(FloatList 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.

See Also:

• Collections.synchronizedList(List)

unmodifiable

public static FloatList unmodifiable(FloatList 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.
