AbstractComponent
ComponentCtrl.redraw(java.io.Writer)
) to render the
properties, excluding the enclosing tag and children.
Default: it renders AbstractComponent.getId()
if it was assigned,
and event names if listened (and listed in AbstractComponent.getClientEvents()
).
Note: it doesn't render AbstractComponent.getWidgetClass()
, AbstractComponent.getUuid()
and AbstractComponent.getMold()
, which are caller's job.

java.io.IOException
protected void redrawChildrenDirectly(TagRenderContext rc, Execution exec, java.io.Writer out) throws java.io.IOException
AbstractTag
AbstractTag.redraw(java.io.Writer)
is going to render
the content (HTML tags) directly.
If it is about to generate the JavaScript code
AbstractComponent.redrawChildren(java.io.Writer)
will be called instead.
You have to override this method if the deriving class has additional information to render.
