Public Class AudienceManager _
    Implements IRuntimeFilter2

public class AudienceManager : IRuntimeFilter2

Remarks

The AudienceManager class is the entry point for the audience feature in Microsoft Office SharePoint Server 2007. It provides an implementation of IRuntimeFilter, which allows Web Parts and other content to be targeted to a specific audience. The AudienceManager class supports run-time functionality such as the retrieval of audience lists to which the user belongs. After you create an instance of the AudienceManager class, you can retrieve individual audience types, lists of audiences, and lists of users who are associated with an audience.

There are several default authentication rules and scopes implemented for the AudienceManager object:

• Members of the Administrator site group for SharePoint Server can view and modify the audiences associated with a portal site.

• Members of the Administrator site group can also view audience information for other portal sites with which they share services. Shared services are portal services that are shared across server farms. The services are centrally managed from a single server for two or more server farms.

• Members of the Administrator site group of the parent portal site can list and view audience information for child portal sites. This information is read-only.

• A member of the Reader or Contributor site group can access only a list of audiences to which he or she belongs. This information is returned by the overloaded GetUserAudienceIDs method.

Examples

This code example shows how to create a rules-based audience to which you can target content.
