JavaGenericNodeStyle. This implementation
delegates to the renderer of the wrapped style.
Developers usually have to override the createDisplayObject and
updateDisplayObject methods.
If the style should be serializable, the serializer property
has also to be overridden to return an appropriate serializer. In that case,
the corresponding deserializer has to be registered to the RoundtripHandler
or IOHandler

| calculateBounds | () | method |
Hide Inherited Public Properties
Show Inherited Public Propertiesoverride public function calculateBounds(scratch:IMutableRectangle, ctx:ICanvasContext):IRectangleThis implementation delegates to the renderer of the wrapped style. Returns a tight rectangular area where the whole rendering would fit into.
Implementations can use the scratch rectangle to put their
results in and return it as the result of the operation.
Client has to always provide a non-null instance as
a parameter. They may however decide to return an internally
cached or dynamically created IRectangle implementation and
disregard the scratch parameter.
If calculating the bounds is too expensive or the painting is not
bound to a certain area, this method may return null.
If nothing is painted, this method should return an empty rectangle, where
either or both the width and height is non-positive or
ImmutableRectangle.Empty.
Parameters
scratch:IMutableRectangle — An instance that can optionally be used to fill with the
corresponding values and be returned
| |
ctx:ICanvasContext — The context to calculate the bounds for (currently not used)
|
IRectangle — The bounds or null to indicate an unbound area
|
| configure | () | method |
override protected function configure():void
This implementation does nothing.
This is an empty implementation of the AbstractStyleRenderer.configure
method. Subclasses should override this.
| createDisplayObject | () | method |
override public function createDisplayObject(context:IDisplayObjectContext):DisplayObjectParameters
context:IDisplayObjectContext |
DisplayObject |
| createSerializer | () | method |
protected function createSerializer():IRealizerSerializer
A ISerializer which can serialize DelegatingStyle instances.
This implementation returns a JavaGenericNodeRealizerSerializer and thus
does not need to be overridden.
Subclasses can, however, override this method to return a custom serializer or
null if the style is not intended to be serialized.
IRealizerSerializer — A suitable serializer or null.
|
| getIntersection | () | method |
override public function getIntersection(innerX:Number, innerY:Number, outerX:Number, outerY:Number, intersectionPoint:IPointSetter):Boolean
This implementation delegates to the renderer of the wrapped style.
Finds an intersection for the current item using the style.
This implementation returns the intersection for the layout.
Parameters
innerX:Number — The x coordinate of the point inside the node.
| |
innerY:Number — The y coordinate of the point inside the node.
| |
outerX:Number — The x coordinate of the point outside the node.
| |
outerY:Number — The y coordinate of the point outside the node.
| |
intersectionPoint:IPointSetter — The point to store the coordinates of the intersection in.
|
Boolean — true if an intersection was actually found
|
| getOutline | () | method |
override public function getOutline():GeneralPath
This implementation delegates to the renderer of the wrapped style.
Returns the outline of the shape using the node's layout.
GeneralPath — The outline of the bounds of the node.
|
| getShapeGeometry | () | method |
override public function getShapeGeometry(node:INode, style:INodeStyle):IShapeGeometry
Gets an implementation of the IShapeGeometry interface that can
handle the provided node and its associated style.
If the IDelegatingStyle wraps an INodeStyle,
this implementation delegates to the renderer of the wrapped style,
otherwise it returns null.
Parameters
node:INode — The node to provide an instance for
| |
style:INodeStyle — The style to use for the painting
|
IShapeGeometry — An implementation that may be used to subsequently query geometry information from.
Clients should not cache this instance and must always call
this method immediately before using the value returned. This enables the
use of the flyweight design pattern for implementations
|
| isHit | () | method |
override public function isHit(x:Number, y:Number, ctx:ICanvasContext):BooleanThis implementation delegates to the renderer of the wrapped style. Hit tests the item by trying to apply the flash internal hit testing.
This implementation does not take ICanvasContext.hitTestRadius into account.
Parameters
x:Number | |
y:Number | |
ctx:ICanvasContext |
Boolean |
| isInBox | () | method |
override public function isInBox(box:IRectangle, ctx:ICanvasContext):Boolean
This implementation delegates to the renderer of the wrapped style.
Returns true if the corresponding
item is considered to intersect the given rectangular box.
This method may return false if the item cannot be
selected using a selection marquee or optionally if the
item is only partially contained within the box.
Parameters
box:IRectangle — The box describing the marquee's bounds
| |
ctx:ICanvasContext — The current canvas context
|
Boolean — true if the item is considered to be captured by the marquee
|
| isInside | () | method |
override public function isInside(x:Number, y:Number):BooleanThis implementation delegates to the renderer of the wrapped style. Checks whether the given coordinate lies within the shape's geometric bounds.
This implementation checks for containment in the layout.
Parameters
x:Number — The x coordinate of the point to test.
| |
y:Number — The y coordinate of the point to test.
|
Boolean — True if the point lies within the geometry of the rendering.
|
| lookup | () | method |
override public function lookup(type:Class):Object
ILookup implementation of this style renderer.
If asked for an ISerializer it returns the result of
createSerializer (may be null). Otherwise it returns itself,
if the renderer implements the asked type. If not and if the renderer of the
wrapped style implements ILookup, that renderer's lookup will
be queried.
Parameters
type:Class — The type to look for.
|
Object — An instance of the asked type if available, otherwise null.
