Merging them would add only a message element and an endpoint address to the connection object and would simplify close() isclosed() and GC's life quite a bit. (Look Ma, no synch ! All synchronized() have been removed. With the help of a volatile reference to the TcpConnection, this is no longer necessary this optimizes at least one critical function: isClosed().<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>(package private) <A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpConnection.html" title="class in net.jxta.impl.endpoint.tcp">TcpConnection</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpMessenger.html#conn">conn</A></B></CODE><BR> The connection</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>(package private) boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpMessenger.html#incoming">incoming</A></B></CODE><BR> If this is an incoming connection we must not close it when this messenger disapears. </TD></TR></TABLE> <A NAME="fields_inherited_from_class_net.jxta.impl.endpoint.BasicMessenger"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class net.jxta.impl.endpoint.<A HREF="../../../../../net/jxta/impl/endpoint/BasicMessenger.html" title="class in net.jxta.impl.endpoint">BasicMessenger</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../../../net/jxta/impl/endpoint/BasicMessenger.html#closed">closed</A>, <A HREF="../../../../../net/jxta/impl/endpoint/BasicMessenger.html#dstAddress">dstAddress</A>, <A HREF="../../../../../net/jxta/impl/endpoint/BasicMessenger.html#propertyChangeSupport">propertyChangeSupport</A></CODE></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"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>(package private)</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpMessenger.html#TcpMessenger(net.jxta.endpoint.EndpointAddress, net.jxta.impl.endpoint.tcp.TcpConnection, net.jxta.impl.endpoint.tcp.TcpTransport)">TcpMessenger</A></B>(<A HREF="../../../../../net/jxta/endpoint/EndpointAddress.html" title="class in net.jxta.endpoint">EndpointAddress</A> destaddr, <A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpConnection.html" title="class in net.jxta.impl.endpoint.tcp">TcpConnection</A> conn, <A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpTransport.html" title="class in net.jxta.impl.endpoint.tcp">TcpTransport</A> p)</CODE><BR> Create a new TcpNonBlockingMessenger for the specified address.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>(package private)</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpMessenger.html#TcpMessenger(net.jxta.endpoint.EndpointAddress, net.jxta.impl.endpoint.tcp.TcpTransport)">TcpMessenger</A></B>(<A HREF="../../../../../net/jxta/endpoint/EndpointAddress.html" title="class in net.jxta.endpoint">EndpointAddress</A> destaddr, <A HREF="../../../../../net/jxta/impl/endpoint/tcp/TcpTransport.html" title="class in net.jxta.impl.endpoint.tcp">TcpTransport</A> p)</CODE><BR> Create a new TcpNonBlockingMessenger for the specified address.</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"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></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="../../../../../net/jxta/impl/endpoint/tcp/TcpMessenger.html#close()">close</A></B>()</CODE><BR> Close this messenger after processing any pending messages.
