java.lang.Object
org.jivesoftware.openfire.pep.PEPService
All Implemented Interfaces:
Serializable, PubSubService, Cacheable

public class PEPService extends Object implements PubSubService, Cacheable
A PEPService is a PubSubService for use with XEP-0163: "Personal Eventing via Pubsub" Version 1.0 Note: Although this class implements Cacheable, instances should only be cached in caches that have time-based (as opposed to size-based) eviction policies.

If the recipient is not the owner of this service, has no subscription to the root collection node, has not yet been authorized, or is pending to be configured -- then no notifications are going to be sent.

      Depending on the subscription configuration the event notifications may or may not have a payload, may not be sent if a keyword (i.e. filter) was defined and it was not matched.

      Parameters:
      recipientJID - the recipient that is to receive the last published item notifications.
    • sendLastPublishedItems

      public void sendLastPublishedItems(org.xmpp.packet.JID recipientJID, Set<String> nodeIdFilter)

If the recipient is not the owner of this service, has no subscription to the root collection node, has not yet been authorized, or is pending to be configured -- then no notifications are going to be sent.

      Depending on the subscription configuration the event notifications may or may not have a payload, may not be sent if a keyword (i.e. filter) was defined and it was not matched. An optional filter for nodes to be processed can be provided in the second argument to this method. When non-null only the nodes that match an ID in the argument will be processed.

      Parameters:
      recipientJID - the recipient that is to receive the last published item notifications.
      nodeIdFilter - An optional filter of nodes to process (only IDs that are included in the filter are processed).
