ViewableFilter (sakai-announcement-api 22.4 API)

java.lang.Object
- org.sakaiproject.announcement.api.ViewableFilter

All Implemented Interfaces:

Filter
```
public class ViewableFilter
extends Object
implements Filter
```
Allows some basic functions on announcements. Due to limitations of EntityBroker the internal URLs of the announcements service can't be exposed directly, so we have to map them, with assumptions about characters used in IDs. Basically we pack together the {siteId}:{channelId}:{announcementId} into the ID.
