Constructor Detail

HsqlArrayList

public HsqlArrayList(java.lang.Object[] data,
                     int count)

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

HsqlArrayList

public HsqlArrayList(int initialCapacity)

Creates a new instance with the given initial capacity

Method Detail

add

public void add(int index,
                java.lang.Object element)

Inserts an element at the given index

Specified by:

add in interface HsqlList

add

public boolean add(java.lang.Object element)

Appends an element to the end of the list

Specified by:

add in interface Collection

Specified by:

add in interface HsqlList

get

public java.lang.Object get(int index)

Gets the element at given position

Specified by:

get in interface HsqlList

indexOf

public int indexOf(java.lang.Object o)

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

remove

public java.lang.Object remove(int index)

Removes and returns the element at given position

Specified by:

remove in interface HsqlList

set

public java.lang.Object set(int index,
                            java.lang.Object element)

Replaces the element at given position

Specified by:

set in interface HsqlList

size

public final int size()

Returns the number of elements in the array list

Specified by:

size in interface Collection

Specified by:

size in interface HsqlList

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

setSize

public void setSize(int newSize)

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

toArray

public java.lang.Object[] toArray()

toArray

public java.lang.Object[] toArray(int start,
                                  int limit)

toArray

public java.lang.Object toArray(java.lang.Object a)

Copies all elements of the list to a[]. It is assumed a[] is of the correct type. 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.

sort

public void sort(java.util.Comparator c)

getArray

public java.lang.Object[] getArray()

contains

public boolean contains(java.lang.Object o)

remove

public boolean remove(java.lang.Object o)

addAll

public boolean addAll(Collection other)

addAll

public boolean addAll(java.lang.Object[] array)

isEmpty

public boolean isEmpty()

toString

public java.lang.String toString()

Returns a string representation

Overrides:

toString in class java.lang.Object

iterator

public Iterator iterator()
