Method Detail

redraw

public void redraw(java.io.Writer out)
            throws java.io.IOException

Description copied from class: AbstractComponent

Redraws this component. This method implements the mold mechanism.

1. It first invokes AbstractComponent.getMoldURI() to retrieve the mold to redraw. The mold is either an URI (String) or a ComponentRenderer instance.
2. If URI, it invokes Execution.include(java.io.Writer, java.lang.String, java.util.Map, int) to generate the output.
3. If a ComponentRenderer instance, ComponentRenderer.render(org.zkoss.zk.ui.Component, java.io.Writer) is called to generate the output.

Specified by:

redraw in interface Component

Overrides:

redraw in class AbstractComponent

Throws:

java.io.IOException
