Property Detail
emptyproperty
empty:Boolean  [read-only] [override]

Answers if this HashSet has no elements, a size of zero.


Implementation
    public function get empty():Boolean

length
lengthproperty 
length:int  [read-only] [override]

Answers the number of elements in this HashSet.


Implementation
    public function get length():int
Constructor Detail
HashSet()Constructor
public function HashSet(init:Boolean = true)

Constructs a new empty instance of HashSet.

Parameters
init:Boolean (default = true) — An internally used switch to help handle proper instance initialization in inheritance chains where classes can have multiple constructor-like factory methods. This parameter can safely be ignored/omitted when calling the constructor.
Method Detail
addItem()method
override public function addItem(object:Object):Boolean

Adds the specified object to this HashSet.

Parameters

object:Object — the object to add

Returns
Boolean — true when this HashSet did not already contain the object, false otherwise
clear()method 
override public function clear():void

Removes all elements from this HashSet, leaving it empty.

empty
length
clone()method 
override public function clone():Object

Answers a new HashSet with the same elements and size as this HashSet.

Returns
Object — a shallow copy of this HashSet
