Package	com.yworks.graph.drawing.compat
Class	public class JavaGenericNodeStyleRenderer
Inheritance	JavaGenericNodeStyleRenderer JavaNodeStyleRenderer AbstractNodeStyleRenderer AbstractStyleRenderer Object

An abstract renderer which can be used as base class for renderers which handle styles which are derived from JavaGenericNodeStyle.

The following methods can be overridden to model the GenericNodeRealizer implementations:

Purpose	Java implementation	Flex method
Rendering	`GenericNodeRealizer.Painter.paintNode()`	`paintNode()`
Hit testing	`GenericNodeRealizer.ContainsTest.contains()`	`isHit()`
Intersection	`GenericNodeRealizer.IntersectionTest.findIntersection()`	`getIntersection()`
Bounds calculation	`GenericNodeRealizer.UnionRectCalculator.calcUnionRect()`	`calculateBounds()`

Generally it is sufficient to refactor the Java methods to Flex / ActionScript.

Method Detail

lookup

()

method

override public function lookup(type:Class):Object

If asked for a IRealizerSerializer, this method will return a JavaGenericNodeRealizerSerializer. 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

Returns

Object — An implementation of the given type or null

paint

()

method

override protected function paint(g:YGraphics, ctx:IDisplayObjectContext):void

Paints the node. If a drop shadow is enabled, it will be painted, too.

Subclasses should not override this method but paintNode(YGraphics, IPaintContext).

Parameters

	`g:YGraphics` — The graphics to draw on.

	`ctx:IDisplayObjectContext` — The paint context.
