/**
|
||||
* A last activity manager for handling information about the last activity associated
|
||||
* with a Jabber ID. A manager handles incoming LastActivity requests of existing
|
||||
* XMPPConnections. It also allows to request last activity information of other users.<p>
|
||||
*
|
||||
* LastActivity (JEP-012) based on the sending JID's type allows for retrieval of:
|
||||
* <ol>
|
||||
* <li>How long a particular user has been idle
|
||||
* <li>How long a particular user has been logged-out and the message the specified when doing so.
|
||||
* <li>How long a host has been up.
|
||||
* </ol>
|
||||
* <p/>
|
||||
*
|
||||
* For example to get the idle time of a user logged in a resource, simple send the
|
||||
* LastActivity packet to them, as in the following code:<p>
|
||||
*
|
||||
* <pre>
|
||||
* XMPPConnection con = new XMPPConnection("jabber.org");
|
||||
* con.login("john", "doe");
|
||||
* LastActivity activity = LastActivity.getLastActivity(con, "xray@jabber.org/Smack");
|
||||
* </pre>
|
||||
*
|
||||
* To get the lapsed time since the last user logout is the same as above but with
|
||||
* out the resource:
|
||||
* <pre>
|
||||
* LastActivity activity = LastActivity.getLastActivity(con, "xray@jabber.org");
|
||||
* </pre>
|
||||
*
|
||||
* To get the uptime of a host, you simple send the LastActivity packet to it, as in the
|
||||
* following code example:<p>
|
||||
*
|
||||
* <pre>
|
||||
* LastActivity activity = LastActivity.getLastActivity(con, "jabber.org");
|
||||
* </pre>
