Interface IPortletInstanceManager

All Known Subinterfaces:
  PortalCustomizationManager

    public interface IPortletInstanceManager

This is the primary interface for performing persistent store operations on `PortletInstances`. In general this interface provides coarse grain getters and fine grain setters.

It is important to note that all methods on this interface are fully internationalized and entitled. All `titles` and `descriptions` on the objects returned by these methods are internationalized to the preferred locale. Also, all methods are entitled, meaning if the caller does not have the required credentials the method may return a subset of the actual list or be unable to perform the specified function.

Most "Instances" can be thought of as objects tied to a desktop, An Admin has instances derived from the library Definition, and the "end user" has instances derived from the admin instance. Changes made via these APIs require a DesktopDefinitionId and the changes are scoped to that desktop. In other words changes made here do not affect the library or other Desktops. If the "visitorMode" on the customization Context is set the false (default) and the user executing the call is in the "Admin" or "PortalSystemAdministrator" role then these changes take affect at the admin level, and affect ALL users. If the visitorMode is false then the changes only affect the calling user.

  `CustomizationContext.setVisitorMode(boolean)`
  This interface is intended to be implemented only by Oracle Weblogic Portal. Oracle Systems reserves the right to add abstract methods to this interface without notice. Implementations of this interface by other parties must not be expected to compile without change in future versions of Oracle Weblogic Portal.
