Method Detail

getRenderingUINode

protected abstract UINode getRenderingUINode(RenderingContext context,
                                             UINode node)

render

public void render(RenderingContext context,
                   UINode node)
            throws java.io.IOException

Render a UINode in a RenderingContext.

Specified by:

render in interface Renderer

prerender

protected void prerender(RenderingContext context,
                         UINode node)
                  throws java.io.IOException

Called to render the portion before the contents.

Parameters:

context - the rendering context

node - the current UINode

postrender

protected void postrender(RenderingContext context,
                          UINode node)
                   throws java.io.IOException

Called to render the portion after the contents. Default implementation does nothing.

Parameters:

context - the rendering context

node - the current UINode

renderWithNode

protected void renderWithNode(RenderingContext context,
                              UINode node,
                              UINode renderingUINode)
                       throws java.io.IOException

renderInCompositeContext(RenderingContext,UINode,UINode)

renderInCompositeContext

public static void renderInCompositeContext(RenderingContext context,
                                            UINode node,
                                            UINode renderingUINode)
                                     throws java.io.IOException

Parameters:

context - the context that node is defined in.

node - this is the node that will be used for data.

renderingUINode - this UINode subtree will be used to do the actual rendering (ie: this is the template UINode). It may pull attributes and/or indexed/named children from node. It renders in its own RenderingContext.

useGlobalCurrentDataObject

protected boolean useGlobalCurrentDataObject(RenderingContext context)

If true, setting the current data object inside the template immediately "escapes" to the outside world. By default, the current data object only "escapes" through ContextPoppingUINodes (and the corresponding UIX element).
