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><P><P><DL><DT><B>Author:</B></DT> <DD>Gabriel Guardincerri</DD></DL><HR><P><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Method Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../../org/jivesoftware/smackx/packet/LastActivity.html" title="class in org.jivesoftware.smackx.packet">LastActivity</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/LastActivityManager.html#getLastActivity(org.jivesoftware.smack.XMPPConnection, java.lang.String)">getLastActivity</A></B>(<A HREF="../../../org/jivesoftware/smack/XMPPConnection.html" title="class in org.jivesoftware.smack">XMPPConnection</A> con, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> jid)</CODE><BR> Returns the last activity of a particular jid.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.lang.Object"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TH ALIGN="left"><B>Methods inherited from class java.lang.<A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A></B></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#clone()" title="class or interface in java.lang">clone</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#equals(java.lang.Object)" title="class or interface in java.lang">equals</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#finalize()" title="class or interface in java.lang">finalize</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#getClass()" title="class or interface in java.lang">getClass</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#hashCode()" title="class or interface in java.lang">hashCode</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#notify()" title="class or interface in java.lang">notify</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#notifyAll()" title="class or interface in java.lang">notifyAll</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#toString()" title="class or interface in java.lang">toString</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#wait()" title="class or interface in java.lang">wait</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#wait(long)" title="class or interface in java.lang">wait</A>, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#wait(long, int)" title="class or interface in java.lang">wait</A></CODE></TD></TR></TABLE> <P><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="1"><FONT SIZE="+2"><B>Method Detail</B></FONT></TH></TR></TABLE><A NAME="getLastActivity(org.jivesoftware.smack.XMPPConnection, java.lang.String)"><!-- --></A><H3>getLastActivity</H3><PRE>public static <A HREF="../../../org/jivesoftware/smackx/packet/LastActivity.html" title="class in org.jivesoftware.smackx.packet">LastActivity</A> <B>getLastActivity</B>(<A HREF="../../../org/jivesoftware/smack/XMPPConnection.html" title="class in org.jivesoftware.smack">XMPPConnection</A> con, <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> jid) throws <A HREF="../../../org/jivesoftware/smack/XMPPException.html" title="class in org.jivesoftware.smack">XMPPException</A></PRE><DL><DD>Returns the last activity of a particular jid.
