Class PortletRenderer

Direct Known Subclasses:

RenderManager

public abstract class PortletRenderer
extends java.lang.Object

A PortletRenderer is the portlet controller responsible for generating the portlet's display (via markup). The renderer use the information passed in the request to determine what "instance" its rendering. If user customizations are supported, the render accesses the personalization manager to get the user specific data.

A renderer is designed for concurrent use. That is a single renderer may have its render() method called concurrently.

Besides specifying the rendering interface, this interface defines constants Renderers use to reference the portals CSS tags. Using these is integral to having your renderer "adopt" the user page style.

The interface also defines constants to represent the various render modes your portlet renderer may/must support.
