InheritanceEdgeSprite Inheritance DataSprite Inheritance DirtySprite Inheritance flash.display.Sprite

Visually represents a connection between two data elements. Examples include an edge in a graph structure or a line between points in a line chart. EdgeSprites maintain source and target properties for accessing the NodeSprites connected by this edge. By default, EdgeSprites are drawn using an EdgeRenderer. EdgeSprites are typically managed by a Data object.

The width of the arrow head. The default is -1, in which case the width is automatically determined based on the arrow height or the line width.

directedproperty 
public var directed:Boolean = false

Flag indicating if this edge is directed (true) or undirected (false).

Constructor detail
EdgeSprite()constructor
public function EdgeSprite(source:NodeSprite = null, target:NodeSprite = null, directed:Boolean = false)

Creates a new EdgeSprite.

Parameters
source:NodeSprite (default = null) — the source node
 
target:NodeSprite (default = null) — the target node
 
directed:Boolean (default = false) — true for a directed edge, false for undirected
Method detail
clear()method
public function clear():void

Clears the edge, removing references to the edge's nodes.

other()method 
public function other(n:NodeSprite):NodeSprite

Given a node upon which this edge is incident, return the other node connected by this edge.

Parameters
n:NodeSprite — a node upon which this edge is incident

Returns
NodeSprite — the other node
render()method 
public override function render():void
