Interface MVCRenderCommand

All Superinterfaces:

MVCCommand

public interface MVCRenderCommand
extends MVCCommand

Provides an interface to handle the render phase of the portlet. This interface can only be used when the portlet is based on MVCPortlet.

The render command that to be invoked is determined by two factors:

• The portlet name that the render URL is referring to.
• The parameter value mvcRenderCommandName of the render URL.

Implementations of this interface must be OSGi components that are registered in the OSGi Registry with the following properties:

• javax.portlet.name: The portlet name associated to this render command.
• mvc.command.name: the command name that matches the parameter value mvcRenderCommandName. This name cannot contain any comma (,).

The method MVCPortlet.render(RenderRequest, RenderResponse) searches the OSGi Registry for the render command that matches both the portlet name with the property javax.portlet.name and the parameter value mvc.command.name with the property mvc.command.name.

When there are multiple render commands registered for the same portlet name and with the same command name, only the render command with the highest service ranking is invoked.
