Default implementation of the
IGraphItemFactory interface.
clearGraphBeforeRead:Boolean [read-write]
Whether to clear an existing graph instance before reading
If set to true, an exisisting graph instance will be cleared
before the graph is read into this instance, otherwise the loaded
raph will be merged into the existing one.
Implementation
public function get clearGraphBeforeRead():Boolean
public function set clearGraphBeforeRead(value:Boolean):void
protected var _createdGraph:IGraph
Graph instance to work on.
public function DefaultGraphElementFactory(graph:IGraph)
Creates an element factory for the given graph instance.
Parameters
| graph:IGraph — graph instance to work on. Creates a new instance if none is provided.
|
public function createBend(context:GraphMLParseContext, edge:Object, index:int):Object
