Interface FloatList

All Superinterfaces:
Collection, Comparable, FloatCollection, List
All Known Implementing Classes:
AbstractFloatList, FloatLists.SynchronizedList, Lists.EmptyList

public interface FloatList
extends List, Comparable, FloatCollection

A type-specific List; provides some additional methods that use polymorphism to reduce type juggling.

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.

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

floatListIterator

public FloatListIterator floatListIterator()
Returns a type-specific list iterator on the list.

The iterator returned by the List.listIterator() method and by this method are identical; however, using this method you can save a type casting.

See Also:
List.listIterator()

floatListIterator

public FloatListIterator floatListIterator(int index)
Returns a type-specific list iterator on the list starting at a given index.

The iterator returned by the List.listIterator() method and by this method are identical; however, using this method you can save a type casting.

See Also:
List.listIterator(int)

floatSubList

public FloatList floatSubList(int from,
                              int to)
See Also:
List.subList(int,int)

size

public 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

public void getElements(int from,
                        float[] a,
                        int offset,
                        int length)
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

public void removeElements(int from,
                           int to)
Removes (hopefully quickly) elements of this type-specific list.

Parameters:
from - the start index (inclusive).
to - the end index (exclusive).

addElements

public void addElements(int index,
                        float[] a)
Add (hopefully quickly) elements to this type-specific list.

Parameters:
index - the index at which to add elements.
a - the array containing the elements.

addElements

public void addElements(int index,
                        float[] a,
                        int offset,
                        int length)
Add (hopefully quickly) elements to this type-specific list.

Parameters:
index - the index at which to add elements.
a - the array containing the elements.
offset - the offset of the first element to add.
length - the number of elements to add.
