Method Detail

add

public void add(int location,
                E object)

Inserts the specified object into this List at the specified location. The object is inserted before any previous element at the specified location. If the location is equal to the size of this List, the object is added at the end.

Specified by:

add in interface List<E>

Overrides:

add in class AbstractList<E>

Parameters:

location - the index at which to insert

object - the object to add

Throws:

UnsupportedOperationException - when adding to this List is not supported

ClassCastException - when the class of the object is inappropriate for this List

IllegalArgumentException - when the object cannot be added to this List

IndexOutOfBoundsException - when location < 0 || >= size()

NullPointerException - when the object is null and this List does not support null elements

addAll

public boolean addAll(int location,
                      Collection<? extends E> collection)

Inserts the objects in the specified Collection at the specified location in this List. The objects are added in the order they are returned from the Collection iterator.

Specified by:

addAll in interface List<E>

Overrides:

addAll in class AbstractList<E>

Parameters:

location - the index at which to insert

collection - the Collection of objects

Returns:

true if this List is modified, false otherwise

Throws:

UnsupportedOperationException - when adding to this List is not supported

ClassCastException - when the class of an object is inappropriate for this List

IllegalArgumentException - when an object cannot be added to this List

IndexOutOfBoundsException - when location < 0 || >= size()

get

public E get(int location)

Returns the element at the specified location in this List.

Specified by:

get in interface List<E>

Specified by:

get in class AbstractList<E>

Parameters:

location - the index of the element to return

Returns:

the element at the specified location

Throws:

IndexOutOfBoundsException - when location < 0 || >= size()

iterator

public Iterator<E> iterator()

Returns an Iterator on the elements of this List. The elements are iterated in the same order that they occur in the List.

Specified by:

iterator in interface Iterable<E>

Specified by:

iterator in interface Collection<E>

Specified by:

iterator in interface List<E>

Overrides:

iterator in class AbstractList<E>

Returns:

an Iterator on the elements of this List

Iterator

listIterator

public abstract ListIterator<E> listIterator(int location)

Returns a ListIterator on the elements of this List. The elements are iterated in the same order that they occur in the List. The iteration starts at the specified location.

Specified by:

listIterator in interface List<E>

Overrides:

listIterator in class AbstractList<E>

Parameters:

location - the index at which to start the iteration

Returns:

a ListIterator on the elements of this List

Throws:

IndexOutOfBoundsException - when location < 0 || >= size()

See Also:

ListIterator

remove

public E remove(int location)

Removes the object at the specified location from this List.

Specified by:

remove in interface List<E>

Overrides:

remove in class AbstractList<E>

Parameters:

location - the index of the object to remove

Returns:

the removed object

Throws:

UnsupportedOperationException - when removing from this List is not supported

IndexOutOfBoundsException - when location < 0 || >= size()

set

public E set(int location,
             E object)

Replaces the element at the specified location in this List with the specified object.

Specified by:

set in interface List<E>

Overrides:

set in class AbstractList<E>

Parameters:

location - the index at which to put the specified object

object - the object to add

Returns:

the previous element at the index

Throws:

UnsupportedOperationException - when replacing elements in this List is not supported

ClassCastException - when the class of an object is inappropriate for this List

IllegalArgumentException - when an object cannot be added to this List

IndexOutOfBoundsException - when location < 0 || >= size()
