Interface DoubleList

All Superinterfaces:

Collection<Double>, Comparable<List<? extends Double>>, DoubleCollection, DoubleIterable, Iterable<Double>, List<Double>

All Known Implementing Classes:

public interface DoubleList
extends List<Double>, Comparable<List<? extends Double>>, DoubleCollection

A type-specific List; provides some additional methods that use polymorphism to avoid (un)boxing.

Note that this type-specific interface extends Comparable: it is expected that implementing classes perform a lexicographical comparison using the standard operator "less then" for primitive types, and the usual compareTo() method for objects.

Additionally, this interface strengthens listIterator(), listIterator(int) and subList(int,int).

Besides polymorphic methods, this interfaces specifies methods to copy into an array or remove contiguous sublists. Although the abstract implementation of this interface provides simple, one-by-one implementations of these methods, it is expected that concrete implementation override them with optimized versions.

Method Detail

iterator

DoubleListIterator iterator()

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

Note that this specification strengthens the one given in List.iterator(). It would not be normally necessary, but Iterable.iterator() is bizarrily re-specified in List.

Specified by:

iterator in interface Collection<Double>

Specified by:

iterator in interface DoubleCollection

Specified by:

iterator in interface DoubleIterable

Specified by:

iterator in interface Iterable<Double>

Specified by:

iterator in interface List<Double>

Returns:

an iterator on the elements of this list.

See Also:

Iterable.iterator()

listIterator

DoubleListIterator listIterator()

Returns a type-specific list iterator on the list.

Specified by:

listIterator in interface List<Double>

See Also:

List.listIterator()

listIterator

DoubleListIterator listIterator(int index)

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

Specified by:

listIterator in interface List<Double>

See Also:

List.listIterator(int)

subList

DoubleList subList(int from,
                   int to)

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 List<Double>

See Also:

List.subList(int,int)

size

void size(int size)

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.

Parameters:

size - the new size.

getElements

void getElements(int from,
                 double[] a,
                 int offset,

Copies (hopefully quickly) elements of this type-specific list into the given array.

Parameters:

from - the start index (inclusive).

a - the destination array.

offset - the offset into the destination array where to store the first element copied.

length - the number of elements to be copied.

removeElements

void removeElements(int from,
                    int to)
