Method Summary

void	render(IMarkupWriter writer, IRequestCycle cycle) The principal rendering/rewinding method.

Method Detail

render

void render(IMarkupWriter writer,
            IRequestCycle cycle)

The principal rendering/rewinding method. This will cause the receiving component to render its top level elements (HTML text and components).

Renderring and rewinding are the exact same process. The same code that renders must be able to restore state by going through the exact same operations (even though the output is discarded).
