| Interface | public interface IArrow |
| Implementors | DefaultArrow |
IEdge.
Instances of this class are used by IEdgeStyle implementations.
| Property | Defined By | ||
|---|---|---|---|
| cropLength : Number [read-only]
Gets the cropping length associated with this instance. | IArrow | ||
| length : Number [read-only]
Returns the length of the arrow, i.e. | IArrow | ||
| Method | Defined By | ||
|---|---|---|---|
Gets an IBoundsProvider implementation that can yield
this arrow's bounds if painted the given location using the
given direction for the given edge. | IArrow | ||
getDisplayObjectCreator(edge:IEdge, atSource:Boolean, anchor:IPoint, direction:IPoint):IDisplayObjectCreator
Gets an implementation of IDisplayObjectCreator that will create
the display object for the arrow. | IArrow | ||
| cropLength | property |
cropLength:Number [read-only] Gets the cropping length associated with this instance.
This value is used by IEdgeStyle implementations to let the
edge appear to end shortly before it's actual target.
public function get cropLength():Number| length | property |
length:Number [read-only] Returns the length of the arrow, i.e. the distance from the arrows tip to the position where the visual representation of the edge's path should begin.
public function get length():Number| getBoundsProvider | () | method |
public function getBoundsProvider(edge:IEdge, atSource:Boolean, anchor:IPoint, direction:IPoint):IBoundsProvider
Gets an IBoundsProvider implementation that can yield
this arrow's bounds if painted the given location using the
given direction for the given edge.
Parameters
edge:IEdge — The edge this arrow belongs to
| |
atSource:Boolean — Whether this will be the source arrow
| |
anchor:IPoint — The anchor point for the tip of the arrow
| |
direction:IPoint — The direction the arrow is pointing in
|
IBoundsProvider — An implementation of the IBoundsProvider
interface that can
subsequently be used to query the bounds. Clients will always call
this method before using the implementation and may not cache the instance returned.
This allows for applying the flyweight design pattern to implementations.
|
| getDisplayObjectCreator | () | method |
public function getDisplayObjectCreator(edge:IEdge, atSource:Boolean, anchor:IPoint, direction:IPoint):IDisplayObjectCreator
Gets an implementation of IDisplayObjectCreator that will create
the display object for the arrow.
This method may always return the same instance. By contract, clients will not cache instances returned, but will always call this method before the methods on the instance will be called.
This contract enables the use of the fly-weight design pattern. Implementations of this class can always return the same instance and configure this instance upon each call to this method.
Parameters
edge:IEdge — The edge this arrow belongs to
| |
atSource:Boolean — Whether this will be the source arrow
| |
anchor:IPoint — The anchor point for the tip of the arrow
| |
direction:IPoint — The direction the arrow is pointing in
|
IDisplayObjectCreator — An implementation of the IDisplayObjectCreator interface that can
subsequently be used to perform the actual painting.
