Enclosing class:

public static class DoubleLists.Singleton
extends AbstractDoubleList
implements Serializable, Cloneable

An immutable class representing a type-specific singleton list.

This class may be useful to implement your own in case you subclass a type-specific list.

Specified by:

removeDouble in interface DoubleList

Overrides:

removeDouble in class AbstractDoubleList

See Also:

List.remove(int)

contains

public boolean contains(double k)

Specified by:

contains in interface DoubleCollection

Overrides:

contains in class AbstractDoubleList

See Also:

Collection.contains(Object)

addAll

public boolean addAll(Collection<? extends Double> c)

Description copied from class: AbstractDoubleList

Delegates to a more generic method.

Specified by:

addAll in interface Collection<Double>

Specified by:

addAll in interface List<Double>

Overrides:

addAll in class AbstractDoubleList

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

addAll

public boolean addAll(int i,
                      Collection<? extends Double> c)

Specified by:

addAll in interface List<Double>

Overrides:

addAll in class AbstractDoubleList

removeAll

public boolean removeAll(Collection<?> c)

Description copied from class: AbstractDoubleCollection

Remove from this collection all elements in the given collection. If the collection is an instance of this class, it uses faster iterators.

Specified by:

removeAll in interface Collection<Double>

Specified by:

removeAll in interface List<Double>

Overrides:

removeAll in class AbstractDoubleCollection

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

retainAll

public boolean retainAll(Collection<?> c)

Description copied from class: AbstractDoubleCollection

Retains in this collection only elements from the given collection.

Specified by:

retainAll in interface Collection<Double>

Specified by:

retainAll in interface List<Double>

Overrides:

retainAll in class AbstractDoubleCollection

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

toDoubleArray

public double[] toDoubleArray()

Description copied from interface: DoubleCollection

Returns a primitive type array containing the items of this collection.

Specified by:

toDoubleArray in interface DoubleCollection

Overrides:

toDoubleArray in class AbstractDoubleCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

listIterator

public DoubleListIterator listIterator()

Description copied from interface: DoubleList

Returns a type-specific list iterator on the list.

Specified by:

listIterator in interface DoubleList

Specified by:

listIterator in interface List<Double>

Overrides:

listIterator in class AbstractDoubleList

See Also:

List.listIterator()

iterator

public DoubleListIterator iterator()

Description copied from interface: DoubleCollection

Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:

iterator in interface DoubleCollection

Specified by:

iterator in interface DoubleIterable

Specified by:

iterator in interface DoubleList

Specified by:

iterator in interface Iterable<Double>

Specified by:

iterator in interface Collection<Double>

Specified by:

iterator in interface List<Double>

Overrides:

iterator in class AbstractDoubleList

Returns:

a type-specific iterator on the elements of this collection.

listIterator

public DoubleListIterator listIterator(int i)

Description copied from interface: DoubleList

Returns a type-specific list iterator on the list starting at a given index.

Specified by:

listIterator in interface DoubleList

Specified by:

listIterator in interface List<Double>

Overrides:

listIterator in class AbstractDoubleList

See Also:

List.listIterator(int)

subList

public DoubleList subList(int from,
                          int to)

Description copied from interface: DoubleList

Returns a type-specific view of the portion of this list from the index from, inclusive, to the index to, exclusive.

Note that this specification strengthens the one given in List.subList(int,int).

Specified by:

subList in interface DoubleList

Specified by:

subList in interface List<Double>

Overrides:

subList in class AbstractDoubleList

See Also:

List.subList(int,int)

size

public int size()

Specified by:

size in interface Collection<Double>

Specified by:

size in interface List<Double>

Specified by:

size in class AbstractCollection<Double>

size

public void size(int size)

Description copied from interface: DoubleList

Sets the size of this list.

If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

Specified by:

size in interface DoubleList

Overrides:

size in class AbstractDoubleList

Parameters:

size - the new size.

clear

public void clear()

Specified by:

clear in interface Collection<Double>

Specified by:

clear in interface List<Double>

Overrides:

clear in class AbstractCollection<Double>

clone

public Object clone()

Overrides:

clone in class Object

rem

public boolean rem(double k)

Description copied from interface: DoubleCollection

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface DoubleCollection

Overrides:

rem in class AbstractDoubleList

See Also:

Collection.remove(Object)

addAll

public boolean addAll(DoubleCollection c)

Description copied from class: AbstractDoubleCollection

Adds all elements of the given type-specific collection to this collection.

Specified by:

Overrides:

addAll in class AbstractDoubleList

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

public boolean addAll(int i,
                      DoubleCollection c)
