Primary class that drives overall FOP process. - * - *

Once this class is instantiated, methods are called to set the - * Renderer to use, the (possibly multiple) ElementMapping(s) to - * use and the PrintWriter to use to output the results of the - * rendering (where applicable). In the case of the Renderer and - * ElementMapping(s), the Driver may be supplied either with the - * object itself, or the name of the class, in which case Driver will - * instantiate the class itself. The advantage of the latter is it - * enables runtime determination of Renderer and ElementMapping(s). - * - *

Once the Driver is set up, the buildFOTree method - * is called. Depending on whether DOM or SAX is being used, the - * invocation of the method is either buildFOTree(Document) or - * buildFOTree(Parser, InputSource) respectively. - * - *

A third possibility may be used to build the FO Tree, namely - * calling getDocumentHandler() and firing the SAX events yourself. - * - *

Once the FO Tree is built, the format() and render() methods may be - * called in that order. - * - *

Here is an example use of Driver from CommandLine.java: - * - * 

- * Driver driver = new Driver();
- * driver.setRenderer("org.apache.fop.render.pdf.PDFRenderer", version);
- * driver.addElementMapping("org.apache.fop.fo.StandardElementMapping");
- * driver.addElementMapping("org.apache.fop.svg.SVGElementMapping");
- * driver.setWriter(new PrintWriter(new FileWriter(args[1])));
- * driver.buildFOTree(parser, fileInputSource(args[0]));
- * driver.format();
- * driver.render();
