Class XmlXslIOHandler

java.lang.Object
  y.io.IOHandler
      y.io.XmlXslIOHandler

public class XmlXslIOHandler
extends IOHandler

IOHandler that is able to read arbitrary XML files. An XSL stylesheet needs to be specified that transforms the input XML file to a valid input file for a reader delegate of type IOHandler.

Constructor Summary

XmlXslIOHandler()
Creates a new instance of the IOHandler.

XmlXslIOHandler(GraphMLIOHandler readerDelegate)
Creates a new instance of the IOHandler with the given reader delegate.

Method Summary

boolean	canWrite() Returns false.
java.lang.String	getFileFormatString() Returns a textual description of the IOHandler.
java.lang.String	getFileNameExtension() Returns the empty string since XML files can have file name extensions.
IOHandler	getReaderDelegate() Returns the IOHandler that will further process the XSL transformed XML input.
javax.xml.transform.Source	getXslSource() Returns the source for the XSL stylesheet to be used to transform the input.
void	read(Graph2D graph, java.io.InputStream in) Adds the contents that are read from the stream to the given graph.
void	setReaderDelegate(GraphMLIOHandler reader) Sets the IOHandler that will further process the XSL transformed XML input.
void	setXslSource(javax.xml.transform.Source xslSource) Sets the source for the XSL stylesheet to be used to transform the input.
void	write(Graph2D graph, java.io.OutputStream out) Writes the contents of the given graph to a stream
