javax.portlet
Class PortletMode

java.lang.Object
  javax.portlet.PortletMode

public class PortletMode
extends java.lang.Object

The PortletMode class represents the possible modes that a portlet can assume.

A portlet mode indicates the function a portlet is performing. Normally, portlets perform different tasks and create different content depending on the function they are currently performing. When invoking a portlet, the portlet container provides the current portlet mode to the portlet.

Portlets can programmatically change their portlet mode when processing an action request.

This class defines the default portlet modes EDIT, HELP, VIEW. Additional portlet modes may be defined by calling the constructor of this class. If a portal/portlet-container does not support a custom portlet mode defined in the portlet application deployment descriptor, the custom portlet mode will be ignored by the portal/portlet container.

Field Summary

          Within the EDIT portlet mode, a portlet should provide content and logic that lets a user customize the behavior of the portlet.

          When in HELP portlet mode, a portlet should provide help information about the portlet.
