| Implements | Collection |
Collection that obeys the 'set' semantics.
An item can only be contained once in the same set. This implementation is based on hash values and equality checks.
| Method | Defined By | ||
|---|---|---|---|
Creates a new hashset using the given values to initialize the set,
or an empty hashset if no values are passed. | HashSet | ||
Adds a collection of elements to this set. | HashSet | ||
addItem(item:Object):Boolean
Adds the given item to this set. | HashSet | ||
clear():void
Removes all of the elements from this collection. | HashSet | ||
contains(item:Object):Boolean
Returns true if this collection contains the specified element. | HashSet | ||
getItemAt(index:int):Object
Not supported. | HashSet | ||
isEmpty():Boolean
Returns true if this collection contains no elements. | HashSet | ||
Returns an iterator over a set of elements. | HashSet | ||
length():uint
Returns the number of elements in this collection. | HashSet | ||
removeItem(item:Object):Boolean
Removes a single instance of the specified element from this collection, if it is present (optional operation). | HashSet | ||
toArray():Array
Returns an array containing all of the elements in this collection. | HashSet | ||
| HashSet | () | Constructor |
public function HashSet(values:Iterable = null)Creates a new hashset using the given values to initialize the set, or an empty hashset if no values are passed.
Parametersvalues:Iterable (default = null) |
