    • highlight

      public void highlight(String name, InputStream in, OutputStream out, String encoding, boolean fragment) throws IOException
      Transforms source code that's provided through an InputStream to highlighted syntax in XHTML and writes it back to an OutputStream.

      If the highlighting has to become a fragment, no CSS styles will be generated.

      For complete documents, there's a collection of default styles that will be included. It's possible to override these by changing the provided jhighlight.properties file. It's best to look at this file in the JHighlight archive and modify the styles that are there already.

      Specified by:
      highlight in interface Renderer
      Parameters:
      name - The name of the source file.
      in - The input stream that provides the source code that needs to be transformed.
      out - The output stream to which to resulting XHTML should be written.
      encoding - The encoding that will be used to read and write the text.
      fragment - true if the generated XHTML should be a fragment; or false if it should be a complete page
      Throws:
      IOException
