Interface ComponentRenderer

public interface ComponentRenderer

A component renderer is used to render a component. In addition to DSP, JSP and other Servlet, a component can be rendered by use of a ComponentRenderer instance.

When AbstractComponent.redraw(java.io.Writer) is called, it retrieves the mold URI by calling AbstractComponent.getMoldURI(). Then, it returns either an URI or a ComponentRenderer instance. If URI, the component is rendered by use of Execution.include(java.io.Writer, java.lang.String, java.util.Map, int). If ComponentRenderer, render(org.zkoss.zk.ui.Component, java.io.Writer) is called directly.

Note: an instance of ComponentRenderer is shared among all components of associated types.

The use of ComponentRenderer is mainly to speed up the performance.
