## com.bea.p13n.ad
Interface AdBucketService

All Superinterfaces:
  ContentBucket, EJBObject, Remote

public interface AdBucketService
extends EJBObject, ContentBucket

The remote bean interface for the AdBucketService. The AdBucketService implements the ContentBucket interface and provides ad content to the PlaceholderService. There are two "buckets" of ad that may be searched. Associated with each user is an AdBucket. If the ad isn't found in the users AdBucket then a global AdBucket is searched. When multiple ads are legal, the AdConflictResolver is called to select the "best" ad to be displayed.

The AdBucketService provides methods to add ads to user AdBuckets. In addition, there is a cleanup method which will remove all of the ads associated with a container.

Preview manages the life time of a query preview and allows all possible content matching the query to be rendered and returned to some type of preview object.
