cern.colt.list.adapter.DoubleListAdapter

All Implemented Interfaces:

Iterable, Collection, List

public class DoubleListAdapter
extends AbstractList
implements List

Adapter that permits an AbstractDoubleList to be viewed and treated as a JDK 1.2 AbstractList. Makes the contained list compatible with the JDK 1.2 Collections Framework.

Any attempt to pass elements other than java.lang.Number to setter methods will throw a java.lang.ClassCastException. java.lang.Number.doubleValue() is used to convert objects into primitive values which are then stored in the backing templated list. Getter methods return java.lang.Double objects.

Method Detail

add

public void add(int index,
       Object element)

Inserts the specified element at the specified position in this list (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

Specified by:

add in interface List

Overrides:

add in class AbstractList

Parameters:

index - index at which the specified element is to be inserted.

element - element to be inserted.

Throws:

ClassCastException - if the class of the specified element prevents it from being added to this list.

IllegalArgumentException - if some aspect of the specified element prevents it from being added to this list.

IndexOutOfBoundsException - index is out of range (index < 0 || index > size()).

get

public Object get(int index)

Returns the element at the specified position in this list.

Specified by:

get in interface List

Specified by:

get in class AbstractList

Parameters:

index - index of element to return.

Returns:

the element at the specified position in this list.

Throws:

IndexOutOfBoundsException - if the given index is out of range (index < 0 || index >= size()).

object

protected static Object object(double element)

Transforms an element of a primitive data type to an object.

remove

public Object remove(int index)

Removes the element at the specified position in this list (optional operation). Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.

Specified by:

remove in interface List

Overrides:

remove in class AbstractList

Parameters:

index - the index of the element to remove.

Returns:

the element previously at the specified position.

Throws:

IndexOutOfBoundsException - if the specified index is out of range (index < 0 || index >= size()).

set

public Object set(int index,
         Object element)

Replaces the element at the specified position in this list with the specified element (optional operation).

Specified by:

set in interface List

Overrides:

set in class AbstractList

Parameters:

index - index of element to replace.

element - element to be stored at the specified position.

Returns:

the element previously at the specified position.

Throws:

ClassCastException - if the class of the specified element prevents it from being added to this list.

IllegalArgumentException - if some aspect of the specified element prevents it from being added to this list.

IndexOutOfBoundsException - if the specified index is out of range (index < 0 || index >= size()).

size

public int size()

Returns the number of elements in this list.

Specified by:

size in interface Collection

Specified by:

size in interface List

Specified by:

size in class AbstractCollection

Returns:

the number of elements in this list.

value

protected static double value(Object element)

Transforms an object element to a primitive data type.
