Installs the model in the canvas at the given group using the styleDescriptor. | AbstractStyleRenderer | |
isHit(x:Number, y:Number, ctx:ICanvasContext):Boolean [override] | SimplePortStyleRenderer | ||
|
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. | AbstractStyleRenderer | |
|
Calls configure and tests the item using the style
for a visible intersection with the clip bounds. | AbstractStyleRenderer | |

Prepares this instance for subsequent calls after the
style and item have been initialized. | SimplePortStyleRenderer | ||
createRenderDataCache():Object
Creates an Object which reflects the current state of the style and the model item. | SimplePortStyleRenderer | ||

| setItem(item:IModelItem):void
Called by the various descriptor getters to initialize the item. | AbstractStyleRenderer | |
| setStyle(style:IVisualStyle):void
Called by the various descriptor getters to initialize the style. | AbstractStyleRenderer | |

Hide Inherited Public Properties
Show Inherited Public Propertiesoverride public function calculateBounds(scratch:IMutableRectangle, ctx:ICanvasContext):IRectangleReturns 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():voidPrepares this instance for subsequent calls after the style and item have been initialized.
Upon invocation the style and item fields have
been populated by the getDisplayObjectCreator or getBoundsProvider
methods.
| createDisplayObject | () | method |
override public function createDisplayObject(context:IDisplayObjectContext):DisplayObjectParameters
context:IDisplayObjectContext |
DisplayObject |
| createRenderDataCache | () | method |
protected function createRenderDataCache():ObjectCreates an Object which reflects the current state of the style and the model item.
ReturnsObject — An Object which reflects the current state of the style and the model item.
|
| createStyleDescriptor | () | method |
override protected function createStyleDescriptor():ICanvasObjectDescriptor
Factory method for the StyleDescriptor property. This method will be called
upon first access to the styleDescriptor property.
ICanvasObjectDescriptor — An ICanvasObjectDescriptor instance that will delegate to this
instance's methods
|
| isHit | () | method |
override public function isHit(x:Number, y:Number, ctx:ICanvasContext):BooleanParameters
x:Number | |
y:Number | |
ctx:ICanvasContext |
Boolean |
| lookup | () | method |
override public function lookup(type:Class):Object
Implements the ILookup interface.
This method will be used by default if getContext has been queried for a
lookup implementation.
Note that it cannot be assumed that configure has already been invoked.
However, normally item and style will be correctly configured
if invoked directly after getContext.
Subclass implementations should make sure to configure this instance before they return this as a result
of a successful lookup.
Parameters
type:Class — The type to query for
|
Object — An implementation of the given type or null
|
| paint | () | method |
protected function paint(g:YGraphics, ctx:IDisplayObjectContext):voidParameters
g:YGraphics | |
ctx:IDisplayObjectContext |
| shouldRepaint | () | method |
protected function shouldRepaint(oldCache:Object):BooleanWhether the current display object should be repainted.
Parameters
oldCache:Object — An object which reflects the state of the style and node
when the object was repainted the last time.
|
Boolean — true if a repaint is necessary.
|
| updateDisplayObject | () | method |
override public function updateDisplayObject(oldDisplayObject:DisplayObject, context:IDisplayObjectContext):DisplayObjectParameters
oldDisplayObject:DisplayObject | |
context:IDisplayObjectContext |

| updateLayout | () | method |
protected function updateLayout(obj:DisplayObject, context:IDisplayObjectContext):voidParameters

| updateRenderDataCache | () | method |
protected function updateRenderDataCache(renderDataCache:Object):ObjectUpdates the given object with the current state of the style and the node.
Parameters
renderDataCache:Object — The object to update.
|
Object — An object with the current state of the style and the node.
