Class FallbackEdgeRealizerSerializer

java.lang.Object
  y.io.graphml.graph2d.AbstractEdgeRealizerSerializer
      y.io.graphml.graph2d.FallbackEdgeRealizerSerializer

All Implemented Interfaces:

EdgeRealizerSerializer

public final class FallbackEdgeRealizerSerializer
extends AbstractEdgeRealizerSerializer

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

Method Summary

boolean	canHandle(EdgeRealizer er, GraphMLWriteContext context) Returns true iff er.getClass() == getRealizerClass().
EdgeRealizer	createRealizerInstance(org.w3c.dom.Node node, GraphMLParseContext context) Create new instance of the Realizer from the given information
static FallbackEdgeRealizerSerializer	getInstance()
java.lang.String	getName() Returns the name of the XML element tag which denotes this type of realizer.
java.lang.String	getNamespaceURI() Returns the target namespace of the toplevel element
java.lang.Class	getRealizerClass() Returns the class of which the realizer is an instance of.
void	parse(EdgeRealizer er, org.w3c.dom.Node domNode, GraphMLParseContext context) Parses the properties from an instance of EdgeRealizer.
void	write(EdgeRealizer edgeRealizer, XmlWriter writer, GraphMLWriteContext context) Writes the realizer element's content.
