Classpublic class BendList
ImplementsCollection, IBendList, IControlPoints

A simple implementation of a list of IBends.

This implementation is backed by a com.yworks.support.List.

Property detail
controlPointsproperty
controlPoints:IControlPoints  [read-only]

Provides a live IControlPointList view over the bends in this list.

This is especially convenient for geometric operations, that don't necessarily know how to deal with bends.

Implementation
    public function get controlPoints():IControlPoints
countproperty 
count:uint  [read-only]

Returns the number of elements in this collection.

Implementation
    public function get count():uint
Constructor detail
BendList()constructor
public function BendList(bends:List = null)

Creates a new BendList.

Parameters
bends:List (default = null) — A List to create the BendList from.
Method detail
add()method
public function add(index:uint, bend:IBend):void

Inserts a new bend into the list.

Parameters
index:uint — The index to insert the bend at.
 
bend:IBend — The bend to insert.
addAll()method 
public function addAll(collection:Collection):void

Adds all of the elements in the specified collection to this collection (optional operation).

Parameters
collection:Collection — the collection containing elements to be added to this collection
addItem()method 
public function addItem(item:Object):Boolean

Adds 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

Returns
Boolean — true if this collection changed as a result of the call
bendAt()method 
public function bendAt(index:int):IBend

Returns the IBend at position index in this list.

Parameters
index:int — The index of the bend

Returns
IBend
clear()method 
public function clear():void

Removes 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 this collection contains the specified element.

Parameters
item:Object — element whose presence in this collection is to be tested

Returns
Boolean — true if this collection contains the specified element

public function getItemAt(index:int):Object

Returns the element at the specified position in this collection.

Parameters
index:int — the index of the element to return

Returns
Object — the element at the specified position in this list
getPointAt()method 
public function getPointAt(index:uint):IPoint

Returns the i-th point in the list.

Parameters
index:uint — The zero-based index of the item in this list

Returns
IPoint — The item for the given index
isEmpty()method 
public function isEmpty():Boolean

Returns true if this collection contains no elements.

Returns
Boolean — true if this collection contains no elements
