Package org.jivesoftware.openfire.handler

Class DirectedPresence

java.lang.Object

org.jivesoftware.openfire.handler.DirectedPresence

All Implemented Interfaces:

Externalizable, Serializable, Cacheable

public class DirectedPresence
extends Object
implements Externalizable, Cacheable

Represents a directed presence sent from a session hosted in a cluster node to another entity (e.g. user or MUC service) hosted in some other cluster node.

This information needs to be shared by all cluster nodes so that if a cluster node goes down then directed presences can be correctly cleaned up.

Note that an instance of this class will be created and kept in the clustered cache only when entities hosted by different cluster nodes are involved.

Description copied from interface: Cacheable

Returns the approximate size of the Object in bytes. The size should be considered to be a best estimate of how much memory the Object occupies and may be based on empirical trials or dynamic calculations.

Specified by:

getCachedSize in interface Cacheable

Returns:

the size of the Object in bytes.

Throws:

CannotCalculateSizeException - if the size cannot be calculated
