| Implements | List |
This class also lets you use [ ] array notation to access the getItemAt()
and setItemAt() methods. The for each..in loop is also supported.

| ArrayList | () | Constructor |
public function ArrayList(collection:Iterable = null)Creates a new instance based on the given collection.
Parameterscollection:Iterable (default = null) |
| addAll | () | method |
public function addAll(iter:Iterable):voidAdds all of the elements in the specified collection to this collection (optional operation).
Parameters
iter:Iterable — the collection containing elements to be added to this collection
|
| addItem | () | method |
public function addItem(item:Object):BooleanAdds the specified item to this collection. Returns true if this collection changed as a result of the call. (Returns false if this collection does not permit duplicates and already contains the specified element.)
Parameters
item:Object — element whose presence in this collection is to be ensured
|
Boolean — true if this collection changed as a result of the call
|
| clear | () | method |
public function clear():voidRemoves all of the elements from this collection. The collection will be empty after this method returns.
| contains | () | method |
public function contains(item:Object):Boolean
Returns true if the given item is contained in this
collection. Note that the normal equality operator is
used to check whether the item is contained, i.e. this
method yields true if item == otherItem for one otherItem in the collection.
Parameters
item:Object |
Boolean |
| getItemAt | () | method |
public function getItemAt(index:int):ObjectReturns the element at the specified position in this collection.
Parameters
index:int — the index of the element to return
|
Object — the element at the specified position in this list
|
| indexOf | () | method |
public function indexOf(item:Object):intReturns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
Parameters
item:Object — the element to search for
|
int — the index of the first occurrence of the specified element in this list,
or -1 if this list does not contain the element
|
| insert | () | method |
public function insert(item:Object, index:uint):voidInserts 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).
Parameters
item:Object — element to be inserted
| |
index:uint — index at which the specified element is to be inserted
|
| isEmpty | () | method |
public function isEmpty():BooleanReturnsBoolean |
| iterator | () | method |
public function iterator():IteratorReturns an iterator over a set of elements.
ReturnsIterator — an Iterator.
|
| length | () | method |
public function length():uintReturns the number of elements in this collection.
Returnsuint — the number of elements in this collection
|
| removeAt | () | method |
public function removeAt(index:uint):voidRemoves the element at the specified position in this list. Shifts any subsequent elements to the left (subtracts one from their indices).
Parameters
index:uint — the index of the element to be removed
|
| removeItem | () | method |
public function removeItem(item:Object):BooleanRemoves a single instance of the specified element from this collection, if it is present (optional operation).
Parameters
item:Object — element to be removed from this collection, if present
|
Boolean — true if an element was removed as a result of this call
|
| sort | () | method |
public function sort(comparisonFunction:Function = null, sortOptions:int = -1):voidSorts the List by using a comparisionFunction.
Parameters
comparisonFunction:Function (default = null) | |
sortOptions:int (default = -1) |
| toArray | () | method |
public function toArray():ArrayCopies the items of this List to an array and returns it.
ReturnsArray |
| toString | () | method |
public function toString():StringReturnsString |
