Method Detail

add

public void add(int location,
                E object)

Description copied from interface: List

Inserts the specified object into this Vector 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>

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 interface: List

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>

Parameters:

location - the index at which to insert

collection - the Collection of objects

Returns:

true if this List is modified, false otherwise

equals

public boolean equals(Object object)

Description copied from class: Object

Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. The implementation in Object returns true only if the argument is the exact same object as the receiver (==).

Specified by:

equals in interface Collection<E>

Specified by:

equals in interface List<E>

Overrides:

equals in class Object

Parameters:

object - Object the object to compare with this object.

Returns:

boolean true if the object is the same as this object false if it is different from this object.

Object.hashCode()

get

public E get(int location)

Description copied from interface: List

Returns the element at the specified location in this List.

Specified by:

get in interface List<E>

Parameters:

location - the index of the element to return

Returns:

the element at the specified location

hashCode

public int hashCode()

Description copied from class: Object

Returns an integer hash code for the receiver. Any two objects which answer true when passed to .equals must answer the same value for this method.

Specified by:

hashCode in interface Collection<E>

Specified by:

hashCode in interface List<E>

Overrides:

hashCode in class Object

Returns:

int the receiver's hash.

See Also:

Object.equals(java.lang.Object)

indexOf

public int indexOf(Object object)

Description copied from interface: List

Searches this List for the specified object and returns the index of the first occurrence.

Specified by:

indexOf in interface List<E>

Parameters:

object - the object to search for

Returns:

the index of the first occurrence of the object

lastIndexOf

public int lastIndexOf(Object object)

Description copied from interface: List

Searches this List for the specified object and returns the index of the last occurrence.

Specified by:

lastIndexOf in interface List<E>

Parameters:

object - the object to search for

Returns:

the index of the last occurrence of the object

listIterator

public ListIterator<E> listIterator()

Description copied from interface: List

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

Specified by:

listIterator in interface List<E>

Returns:

a ListIterator on the elements of this List

See Also:

ListIterator

listIterator

public ListIterator<E> listIterator(int location)

Description copied from interface: List

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>

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 interface: List

Removes the object at the specified location from this List.

Specified by:

remove in interface List<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 interface: List

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

Specified by:

set in interface List<E>

Parameters:

location - the index at which to put the specified object

object - the object to add

Returns:

the previous element at the index

subList

public List<E> subList(int start,
                       int end)

Description copied from interface: List

Returns a List of the specified portion of this List from the start index to one less than the end index. The returned List is backed by this list so changes to one are reflected by the other.

Specified by:

subList in interface List<E>

Parameters:

start - the index at which to start the sublist

end - the index one past the end of the sublist

Returns:

a List of a portion of this List
