Rendering to pdf & html from the same task?

hq4ever

Hello,<br />
<br />
I would like to render from the same rptdesign to pdf and to html.<br />
The idea here is not to lead the database twice.<br />
<br />
Does this code load the DB twice ?<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>task.setRenderOption(pdfOptions);
task.run();
task.setRenderOption(htmlOptions);
task.run();</pre>
Also, would someone mind explaining what <br />
<pre class='_prettyXprint _lang-auto _linenums:0'>task.close</pre> does ?

If you are using the IRunAndRender task, yes it will. However, if you want to render to two different formats and NOT hit the database twice, you can do a Run task, than two seperate Render tasks, something like:

IRunTask runTask = task = engine.createRunTask(engine.openReportDesign(reportPath));

String tempFile = File.createTempFile("brtRun" + id.replace(" ", "_").replace(":", ""), ".tmp").getAbsolutePath();


task.run(tempFile);

task.close();

IRenderOption renderOptionHTML = new HTMLRenderOption();
renderOptionHTML .setOutputFormat("HTML");

IRenderOption renderOptionPDF = new PDFRenderOption();
renderOptionPDF .setOutputFormat("PDF");

IReportDocument document = engine.openReportDocument(tempFile);

IRenderTask htmlTask = engine.createRenderTask(document);
IRenderTask pdfTask = engine.createRenderTask(document);

htmlTask.setRenderOption(renderOptionHTML);
pdfTask.setRenderOption(renderOptionPDF);

htmlTask.run();
pdfTask.run();

htmlTask.close();
pdfTask.close();

Just be sure to set your render options, such as output format or stream, which aren't in the above example.
