Class HsqlLinkedList

java.lang.Object
  org.hsqldb.lib.BaseList
      org.hsqldb.lib.HsqlLinkedList

All Implemented Interfaces:

HsqlList

public class HsqlLinkedList

extends org.hsqldb.lib.BaseList

implements HsqlList

Intended as an asynchronous alternative to HsqlArrayList. Use HsqlArrayList if the list won't be initialized sequentially and if frequent references to specific element positions will be made.

Method Detail

add

public void add(int index,
                Object element)

Inserts element at index.

Specified by:

add in interface HsqlList

Throws:

IndexOutOfBoundsException - if index < 0 or is > size.

add

public boolean add(Object element)

Appends element to the end of this list.

Specified by:

add in interface HsqlList

Returns:

true

get

public Object get(int index)

Gets the element at given position

Specified by:

get in interface HsqlList

Throws:

IndexOutOfBoundsException - if index is not valid index within the list (0 <= index < size).

remove

public Object remove(int index)

Removes and returns the element at index.

Specified by:

remove in interface HsqlList

Throws:

IndexOutOfBoundsException - if index is not valid index within the list (0 <= index < size).

set

public Object set(int index,
                  Object element)

Replaces the current element at index/code> with element.

Specified by:

set in interface HsqlList

Returns:

The current element at index.

size

public final int size()

Accessor for the size of this linked list. The size is the total number of elements in the list and is one greater than the largest index in the list.

Specified by:

size in interface HsqlList

The Node at the given index.

Throws:

IndexOutOfBoundsException - if index is not valid index within the list (0 <= index < size).

isEmpty

public boolean isEmpty()

toString

public String toString()

Returns a string representation

iterator

public Iterator iterator()
