Method Detail

render

public 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).

Specified by:

render in interface IRender

processPath

protected void processPath(StringBuffer str,
                           IRequestCycle cycle,
                           IAsset path)

Called before including any javascript. It does nothing by default, but allows subclasses to change this behavior.

Parameters:
