Class FallbackNodeRealizerSerializer

java.lang.Object
  y.io.graphml.graph2d.AbstractNodeRealizerSerializer
      y.io.graphml.graph2d.FallbackNodeRealizerSerializer

All Implemented Interfaces:

NodeRealizerSerializer

public final class FallbackNodeRealizerSerializer
extends AbstractNodeRealizerSerializer

Fallback implementation of AbstractNodeRealizerSerializer that deserializes common NodeRealizer properties from arbitrary NodeRealizer XML content. This includes geometry and labels.

Method Summary

boolean	canHandle(NodeRealizer nr, GraphMLWriteContext context) Returns true iff nr.getClass() == getRealizerClass().
NodeRealizer	createRealizerInstance(Node node, GraphMLParseContext context) Create new instance of the Realizer from the given information
static FallbackNodeRealizerSerializer	getInstance()
String	getName() Returns the name of the XML element tag which denotes this type of realizer.
String	getNamespaceURI() Returns the target namespace of the toplevel element
Class	getRealizerClass() Returns the class of which the realizer is an instance of.
void	parse(NodeRealizer nr, Node domNode, GraphMLParseContext context) Parses the properties into an instance of NodeRealizer.
void	write(NodeRealizer nr, XmlWriter writer, GraphMLWriteContext context) Writes the realizer element's content.
