HsqlArrayList

public HsqlArrayList()

Creates a new instance of HsqlArrayList

HsqlArrayList

public HsqlArrayList(int initialCapacity,
                     boolean minimize)

Creates a new instance of HsqlArrayList that minimizes the size when empty

Parameters:

initialCapacity - int

minimize - boolean

HsqlArrayList

public HsqlArrayList(int initialCapacity)

Creates a new instance with the given initial capacity

Parameters:

initialCapacity - int

Method Detail

add

public void add(int index,
                E element)

Inserts an element at the given index

Specified by:

add in interface List<E>

Parameters:

index - int

element - E

add

public boolean add(E element)

Appends an element to the end of the list

Specified by:

add in interface Collection<E>

Specified by:

add in interface List<E>

Parameters:

element - E

Returns:

boolean

get

public E get(int index)

Gets the element at given position

Specified by:

get in interface List<E>

Parameters:

index - int

Returns:

E

indexOf

public int indexOf(E o)

returns the index of given object or -1 if not found

Parameters:

o - Object

Returns:

int

contains

public boolean contains(java.lang.Object o)

Specified by:

contains in interface Collection<E>

remove

public boolean remove(E o)

Specified by:

remove in interface Collection<E>

remove

public E remove(int index)

Removes and returns the element at given position

Specified by:

remove in interface List<E>

Parameters:

index - int

Returns:

E

set

public E set(int index,
             E element)

Replaces the element at given position

Specified by:

set in interface List<E>

Parameters:

index - int

element - E

Returns:

E

size

public final int size()

Returns the number of elements in the array list

Specified by:

size in interface Collection<E>

Specified by:

size in interface List<E>

Returns:

int

trim

public void trim()

Trims the array to be the same size as the number of elements.

clear

public void clear()

Specified by:

clear in interface Collection<E>

setSize

public void setSize(int newSize)

Increase or reduce the size, setting discarded or added elements to null.

Parameters:

newSize - int

toArray

public java.lang.Object[] toArray()

toArray

public <T> T[] toArray(T[] array)

Copies all elements of the list to a[].

If a[] is too small, a new array or the same type is returned.

If a[] is larger, only the list elements are copied and no other change is made to the array.

Differs from the implementation in java.util.ArrayList in the second aspect.

Type Parameters:

T - type of array element

Parameters:

array - T[]

Returns:

T[]

toArraySlice

public void toArraySlice(E[] array,
                         int start,
                         int limit)

Copies elements of the list from start to limit to array. The array must be large enough.

Parameters:

array - E[]

start - int

limit - int

getArray

public E[] getArray()

sort

public void sort(java.util.Comparator<? super E> c)

lastIndexOf

public int lastIndexOf(E o)

addAll

public boolean addAll(Collection<? extends E> other)

addAll

public boolean addAll(E[] array)

isEmpty

public boolean isEmpty()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

iterator

public Iterator<E> iterator()
