Re: [birt-pmc] New Engine API Page

Jason,

I like this page, it provides a lot
of useful information and sure would have saved me a lot of time last fall
when I was trying to figure this out.

- You might want to include the code
you sent me yesterday to get the prompt text from a parameter. Anybody
trying to do their own prompting will run into this problem. 
- For the IRunTask and IRenderTask examples,
you might want to present the IRunTask before IRenderTask since that is
the execution sequence. Then use the report document file produced by IRunTask
as input to IRenderTask, so the relationship is clear.  I would also
suggest showing the IRunAndRenderTask example first, as it is the simplest
and gives a natural lead in to performing the operations separately.
- What is the difference between IDataExtractionTask
and IDataPreviewTask?  They both seem to get data out of a report,
but it wasn't clear to me what they do differently and when I'd use one
or the other.
- The javadoc has a IRunTask.run method
that accepts a parameter of type "org.eclipse.birt.core.archive.IDocArchiveWriter
archive".  What is this, as I can't find a reference to it anywhere
else? There also doesn't seem to be a corresponding engine.openReportDocument()
method.

I also have some technical questions
we can take up offline.

I had been wondering about paginated
reports, and the explanation of IRunTask and IRenderTask (I've been using
the combined IRunAndRenderTask) helps a lot.  Is there a way though
to write the report document to a stream instead of a file?  Managing
these files on a server gets tricky because you need to track them and
delete them. You always seem to orphan some files and consequently never
delete them.  I know keeping the report in memory can be problematic
also if the reports are large and use too much virtual memory.

        Mike
