- - ### Method Detail

    - #### render

          void render(MarkupWriter writer,
                    RenderQueue queue)

      Invoked on an object to request that it render itself. This involves a mix of invoking methods on the writer, and queueing up additional commands (often, representing children of the object that was invoked) to perform additional rendering.

      In this way, rendering is a tail recursive algorithm, but is not implemented using tail recursion.
