org.h2.util
Class ObjectArray<T>

java.lang.Object
  org.h2.util.ObjectArray<T>

Type Parameters:

T - the element type

All Implemented Interfaces:

java.lang.Iterable<T>

public class ObjectArray<T>
extends java.lang.Object
implements java.lang.Iterable<T>

The object array is basically the same as ArrayList. It is a bit faster than ArrayList in some versions of Java.

void	add(int index, T value) Insert an element at the given position.
void	add(T value) Append an object at the end of the list.
void	addAll(ObjectArray<? extends T> list) Add all objects from the given list.
void	clear() Remove all elements from the list.
T	get(int index) Get the object at the given index.
int	indexOf(java.lang.Object o) Get the index of the given object, or -1 if not found.
java.util.Iterator<T>	iterator()
static <T> ObjectArray<T>	newInstance() Create a new object with the default initial capacity.
static <T> ObjectArray<T>	newInstance(java.util.Collection<T> collection) Create a new object with all elements of the given collection.

Method Detail

newInstance

public static <T> ObjectArray<T> newInstance(int capacity)

Create a new object with the given initial capacity.

Parameters:

capacity - the initial capacity

Returns:

the object

newInstance

public static <T> ObjectArray<T> newInstance(T... list)

Create a new object with the given values.

Parameters:

list - the initial elements

Returns:

the object

newInstance

public static <T> ObjectArray<T> newInstance()

Create a new object with the default initial capacity.

Returns:

the object

newInstance

public static <T> ObjectArray<T> newInstance(java.util.Collection<T> collection)

Create a new object with all elements of the given collection.

Parameters:

collection - the collection with all elements

Returns:

the object

add

public void add(T value)

Append an object at the end of the list.

Parameters:

value - the value

get

public T get(int index)

Get the object at the given index.

Parameters:

index - the index

Returns:

the value

remove

public java.lang.Object remove(int index)

Remove the object at the given index.

Parameters:

index - the index

Returns:

the removed object

removeRange

public void removeRange(int from,
                        int to)

Parameters:

from - the start index

to - the end index

setSize

public void setSize(int size)

Fill the list with empty elements until it reaches the given size.

Parameters:

size - the new size

trimToSize

public void trimToSize()

Shrink the array to the required size.

add

public void add(int index,

Convert this list to an array. The target array must be big enough.

Parameters:

array - the target array

Returns:

the array

clear

public void clear()
