Class ArrayCanvasList

java.lang.Object

org.pepstock.charba.client.commons.ArrayCanvasList

All Implemented Interfaces:

Iterable<Canvas>, Collection<Canvas>, List<Canvas>

public final class ArrayCanvasList
extends Object

An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted.
The user can access elements by their integer index (position in the list), and search for elements in the list.
This implementation uses a java script array as back-end to store objects (canvas).

Constructor Summary

Constructors

Constructor	Description
ArrayCanvasList()	Creates an empty list

Method Summary

Modifier and Type	Method	Description
void	add(int index, Canvas element)	Inserts the specified element at the specified position in this list. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).
boolean	add(Canvas element)	Appends the specified element to the end of this list
boolean	addAll(int index, Collection<? extends E> collection)
boolean	addAll(Collection<? extends E> collection)	Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator
void	addAll(Canvas... values)	Loads an array of elements in the list
protected boolean	checkRange(int index)	Checks if the index is in the right range.
void	clear()	Removes all of the elements from this list.
boolean	contains(Object object)	Returns true if this list contains the specified element.
boolean	containsAll(Collection<?> collection)	Returns true if this list contains all of the elements of the specified collection.
Canvas	get(int index)	Returns the element at the specified position in this list.
int	indexOf(Object object)	Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
boolean	isEmpty()	Returns true if this list contains no elements
Iterator<E>	iterator()	Returns an iterator over the elements in this list in proper sequence.
int	lastIndexOf(Object object)	Returns the index of the last occurrence of the specified element in this list, or -1 if this list does not contain the element.
ListIterator<E>	listIterator()	Returns a list iterator over the elements in this list
ListIterator<E>	listIterator(int index)	Returns a list iterator over the elements in this list (in proper sequence), starting at the specified position in the list. The specified index indicates the first element that would be returned by an initial call to next. An initial call to previous would return the element with the specified index minus one.
Canvas	remove(int index)	Removes the element at the specified position in this list. Shifts any subsequent elements to the left (subtracts one from their indices).
boolean	remove(Object object)	Removes the first occurrence of the specified element from this list, if it is present.
boolean	removeAll(Collection<?> collection)	Removes from this list all of its elements that are contained in the specified collection.
boolean	retainAll(Collection<?> collection)	Retains only the elements in this list that are contained in the specified collection. In other words, removes from this list all of its elements that are not contained in the specified collection.
Canvas	set(int index, Canvas element)	Replaces the element at the specified position in this list with the specified element.
int	size()	Returns the number of elements in this list.
List<E>	subList(int fromIndex, int toIndex)	Not implemented
Object[]	toArray()
<T> T[]	toArray(T[] a)
String	toString()

Constructor Detail

ArrayCanvasList

public ArrayCanvasList()

Creates an empty list

Method Detail

addAll

public void addAll(Canvas... values)

Loads an array of elements in the list

Parameters:

values - an array of elements to be loaded

add

public boolean add(Canvas element)

Appends the specified element to the end of this list

retainAll

public boolean retainAll(Collection<?> collection)

Retains only the elements in this list that are contained in the specified collection.
In other words, removes from this list all of its elements that are not contained in the specified collection.

clear

public void clear()

Removes all of the elements from this list. The list will be empty after this call returns.

get

public Canvas get(int index)

Returns the element at the specified position in this list. If index out of range, returns null

set

public Canvas set(int index,
                  Canvas element)

Replaces the element at the specified position in this list with the specified element. If index out of range, returns null

add

public void add(int index,
                Canvas element)

Inserts the specified element at the specified position in this list.
Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

remove

public Canvas remove(int index)

Removes the element at the specified position in this list.
Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.

indexOf

public int indexOf(Object object)

Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.

lastIndexOf

public int lastIndexOf(Object object)

Returns the index of the last occurrence of the specified element in this list, or -1 if this list does not contain the element.

toArray

public Object[] toArray()

size

public int size()

Returns the number of elements in this list.

Specified by:

size in interface Collection<E>

Specified by:

size in interface List<E>

isEmpty

public boolean isEmpty()

Returns true if this list contains no elements

Specified by:

isEmpty in interface Collection<E>

Specified by:

isEmpty in interface List<E>

contains

public boolean contains(Object object)

Returns true if this list contains the specified element.

Specified by:

contains in interface Collection<E>

Specified by:

contains in interface List<E>

iterator

public Iterator<E> iterator()

Returns an iterator over the elements in this list in proper sequence.

Specified by:

iterator in interface Collection<E>

Specified by:

iterator in interface Iterable<E>

Specified by:

iterator in interface List<E>

toArray

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

Specified by:

toArray in interface Collection<E>

Specified by:

toArray in interface List<E>

listIterator

public ListIterator<E> listIterator()

Returns a list iterator over the elements in this list

Specified by:

listIterator in interface List<E>

addAll

public final boolean addAll(int index,
                            Collection<? extends E> collection)

Specified by:

addAll in interface List<E>

remove

public final boolean remove(Object object)

Removes the first occurrence of the specified element from this list, if it is present. If this list does not contain the element, it is unchanged.

Specified by:

remove in interface Collection<E>

Specified by:

remove in interface List<E>

addAll

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

Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator
