Class ChainedRenderer

java.lang.Object
  org.mmbase.framework.AbstractRenderer
      org.mmbase.framework.ChainedRenderer

All Implemented Interfaces:

Renderer

public class ChainedRenderer
extends AbstractRenderer

This renderer simply calls the methods of a number of other Renderers sequentially. Only Renderer.Type.HEAD renderers can be chained, because they don't have to produce a well defined block.

Since:

MMBase-1.9
