Method Detail
acceptKey()method
override public function acceptKey(keyElement:XML, scopeType:String):Boolean

This method defines whether a specific key/data pair is handled by the input handler. When it returns true, each occurence of data elements which match the id of the key element are forwarded to the input handler.

Parameters

keyElement:XML — the key element
 
scopeType:String — the scope type for which the key is defined.

One of

  • GraphMLConstants.SCOPE_ALL
  • GraphMLConstants.SCOPE_GRAPH
  • GraphMLConstants.SCOPE_NODE
  • GraphMLConstants.SCOPE_EDGE
  • GraphMLConstants.SCOPE_PORT

Returns
Boolean — true, if this hanlder can handle the data elements asked for.
parseItemData()method 
override protected function parseItemData(context:GraphMLParseContext, graph:IGraph, item:Object, defaultMode:Boolean, dataElement:XML):void

Parse the element for the given item.

Parameters

context:GraphMLParseContext — The parse context
 
graph:IGraph — The graph to work on
 
item:Object — The item.
 
defaultMode:Boolean — true when the default value, which is included in the key element, is processed, false otherwise.
 
dataElement:XML — The data element of the graphml file.

parseRealizer()method 
protected function parseRealizer(nodegraphicsElement:XML, node:INode, layout:IMutableRectangle, context:GraphMLParseContext):INodeStyle

Parse a GraphML node element

Parameters

nodegraphicsElement:XML — The current graph instance
 
node:INode — The label instance
 
layout:IMutableRectangle — A GraphML Node element
 
context:GraphMLParseContext — The current parse context.

Returns
INodeStyle — A node style instance.
