 /**

  * This Layout module is Turbine 2.3.3 VelocityDirectLayout (same package)

  * with methods added for {@link PipelineData}. It is used in Jetspeed-1 portal.

  *

  * By using this layout any view write will immediately call the provided print writer {@link RunData#getOut()} and

  * the HTTP servlet response will be flushed and set the committed flag. This means of course

  * no change to the HTTP response header will be possible afterwards. By setting the {@link RunData#setAction(String)} in the request

  * (not only the model, but also) additional response headers could be set, cft. {@link DefaultPage#doBuild(PipelineData)}.
