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.

Implementations of this interface by other parties must not be expected to compile without change in future versions of BEA Weblogic Portal.

Method Detail

getPortletView

PortletView getPortletView(CustomizationContext customizationContext,
                           PortletInstanceId portletInstanceId)
                           throws RemoteException

Getter for returning an immutable deep PortletView. The PortletView object, unlike the PortletDefinition or the PortletInstance objects contains a full set of references to all child portlets, portlets and so on. The PortletView object, however is immutable.

Parameters

customizationContext - customization information such as Locales and DesktopInstanceId

portletInstanceId - the unique portletInstanceId.

Returns

an immutable deep PortletView object if one exists, otherwise null.

Throws

RemoteException

getPortletInstance

PortletInstance getPortletInstance(CustomizationContext customizationContext,
                                   PortletInstanceId portletInstanceId)
                                   throws RemoteException

Getter for returning a single PortletInstance.

Parameters

customizationContext - the preferred language, country and variant to which the titles and descriptions are returned.

Returns

a fully populated PortletInstance object.

Throws

RemoteException

updatePortletInstance

PortletInstance updatePortletInstance(CustomizationContext customizationContext,
                                      DesktopDefinitionId desktopDefinitionId,
                                      PortletInstance portletInstance)
                                      throws RemoteException,
                                             ObjectNotFoundException,
                                             NotEntitledException

Update the portlet instance with the new data. If the portlet instance is the primary portlet instance then a new instance will be created specifically for this user or admin.

For an admin editing a portlet outside the context of a desktop (i.e. in a library) you should use updatePortletInstance(PortletInstance)

.

Parameters

desktopDefinitionId - the desktop context this instance is associated with.

portletInstance - the portlet instance containing the new data

Returns

the new updated portlet instance, with possible a new portletInstanceId

Throws

ObjectNotFoundException - if the PortletInstanceId in the PortletInstance, or desktopInstanceId is bogus.

RemoteException

NotEntitledException
