Package	Description

Class	Description
Announcement	An announcement is the information exchanged by the topology connector and contains all clusters and instances which both the topology connector client and servlet see (in their part before joining the two worlds).
AnnouncementFilter	Filter used during announcement processing internally
AnnouncementRegistry	The announcement registry keeps track of all the announcement that this instance either received by a joined topology connector or that a topology connector inherited from the counterpart (the topology connector servlet)
AnnouncementRegistryImpl	Default implementation of the AnnouncementRegistry which handles JSON-backed announcements and does so by storing them in a local like /var/discovery/impl/clusterNodes/$slingId/announcement.
CachedAnnouncement	With SLING-3389 the Announcement itself doesn't use the created (ie timeout) field anymore (it still has it currently for backwards compatibility on the wire-level) - hence that's why there's this small in-memory wrapper object which contains an Announcement and carries a lastHeartbeat property.
