[AXIOM] How to serialize axiom document without building objects in memory

[Tammy Dugan <td...@regenstrief.org>]

I have the following code:

new Thread(new ReadDeferred(writer, (OMElement) 
returnData.createRawDataOutputFromTable(doc,
            inputDatasetId,
            outputDatasetId, type, false)
               )).start();
        ;
        writer.close();

class ReadDeferred
    implements Runnable
{
    Writer writer = null;
    OMElement topElement = null;
    public ReadDeferred(Writer writer, OMElement topElement)
    {
        this.writer = writer;
        this.topElement = topElement;
    }

    public void run()
    {
        try
        {
            topElement.serializeAndConsume(writer);
        }
        catch (Exception ex)
        {
            InitializationServlet.error("", ex);
        }
    }
}


I am trying to flush the output of createRawDataOutputFromTable directly 
to a file without creating a dom tree. The createRawDataOutputFromTable 
method builds an OMDocument using a series of append child statements. 
The above code still holds the whole dom tree in memory before it writes 
to a file. Is there a way I can prevent this? I essentially want every 
appendChild to write the child to the file.
