InheritanceEdgeStyleInputHandler Inheritance AbstractInputHandler Inheritance Object

This class manages the deserialization of all edge styles in the graphml input.

To deserialize a custom style, AbstractEdgeDeserialzer instances can be registered with GraphMLIOHandler.registerDeserializer, which will be used automatically by this handler.

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, element:XML):void

Parses the data.

Parameters

context:GraphMLParseContext — The current parse context
 
graph:IGraph — The current graph
 
item:Object — The current edge
 
defaultMode:Boolean — Whether to parse default data
 
element:XML — The current xml data element
