Method Detail

add

public void add(int location,
                E object)

Description copied from class: AbstractList

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.

Concrete implementations that would like to support the add functionality must override this method.

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.

addAll

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

Description copied from class: AbstractList

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's 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.

get

public E get(int location)

Description copied from class: AbstractList

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 index.

iterator

public Iterator<E> iterator()

Description copied from class: AbstractList

Returns an iterator on the elements of this list. The elements are iterated in the same order as they occur in the list.

Specified by:

iterator in interface Collection<E>

Specified by:

iterator in interface Iterable<E>

Specified by:

iterator in interface List<E>

Overrides:

iterator in class AbstractList<E>

Returns:

an iterator on the elements of this list.

See Also:

Iterator

listIterator

public abstract ListIterator<E> listIterator(int location)

Description copied from class: AbstractList

Returns a list iterator on the elements of this list. The elements are iterated in the same order as 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.

See Also:

ListIterator

remove

public E remove(int location)

Description copied from class: AbstractList

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.

set

public E set(int location,
             E object)

Description copied from class: AbstractList

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.
