Input handler that delegates deserialization to IRealizerSerializer instances.


Public Methods
 MethodDefined by
  
acceptKey(keyElement:XML, scopeType:String):Boolean
This method defines whether a specific key/data pair is handled by the input handler.
ReadEdgeRealizerHandler
 Inherited
applyDefault(context:GraphMLParseContext, defaultElement:XML, value:Object):void
This method is invoked when no data tag is defined, and the default value should be applied.
AbstractInputHandler
 Inherited
parseData(context:GraphMLParseContext, defaultValue:Boolean, dataElement:XML):void
Forwards to parseItemData This method is invoked each time a data element with matching key is processed.
AbstractInputHandler
 Inherited
parseDefaultData(context:GraphMLParseContext, keyElement:XML):Object
This method is invoked when the default value of the key element for a data element is parsed.

Method detail
acceptKey()method
public override 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 
protected override 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(graph:IGraph, edge:IEdge, edgegraphicsElement:XML, context:GraphMLParseContext):IEdgeStyle

Parse the given edgegraphics GraphML element using an IRealizerSerializer instance fetched from the RealizerSerializerManager.

Parameters
graph:IGraph
 
edge:IEdge
 
edgegraphicsElement:XML
 
context:GraphMLParseContext

Returns
IEdgeStyle
