The server is also responsible for responding Multi-User Chat disco requests as well as removing inactive users from the rooms after a period of time and to maintain a log of the conversation in the rooms that require to log their conversations. The conversations log is saved to the database using a separate process<p> Temporary rooms are held in memory as long as they have occupants. They will be destroyed after the last occupant left the room. On the other hand, persistent rooms are always present in memory even after the last occupant left the room. In order to keep memory clean of persistent rooms that have been forgotten or abandoned this class includes a clean up process. The clean up process will remove from memory rooms that haven't had occupants for a while. Moreover, forgotten or abandoned rooms won't be loaded into memory when the Multi-User Chat service starts up.<P><P><DL><DT><B>Author:</B></DT> <DD>Gaston Dombiak</DD></DL><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_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>Field Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="../../../../../org/jivesoftware/openfire/muc/MUCEventDelegate.html" title="class in org.jivesoftware.openfire.muc">MUCEventDelegate</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl.html#mucEventDelegate">mucEventDelegate</A></B></CODE><BR> Delegate responds to events for the MUC service.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> long</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl.html#totalChatTime">totalChatTime</A></B></CODE><BR> The total time all agents took to chat *</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_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>Constructor Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../../../org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl.html#MultiUserChatServiceImpl(java.lang.String, java.lang.String, java.lang.Boolean)">MultiUserChatServiceImpl</A></B>(<A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> subdomain, <A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> description, <A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Boolean.html" title="class or interface in java.lang">Boolean</A> isHidden)</CODE><BR> Create a new group chat server.</TD></TR></TABLE> <!-- ========== 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> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl.html#addExtraFeature(java.lang.String)">addExtraFeature</A></B>(<A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> feature)</CODE><BR> Adds an extra Disco feature to the list of features returned for the conference service.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl.html#addExtraIdentity(java.lang.String, java.lang.String, java.lang.String)">addExtraIdentity</A></B>(<A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> category, <A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> name, <A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> type)</CODE><BR> Adds an extra Disco identity to the list of identities returned for the conference service.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl.html#addSysadmin(java.lang.String)">addSysadmin</A></B>(<A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> userJID)</CODE><BR> Adds a new system administrator of the MUC service.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl.html#addUserAllowedToCreate(java.lang.String)">addUserAllowedToCreate</A></B>(<A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> userJID)</CODE>⌨️ 快捷键说明
