A rarely used convenience in itself since one should hardly ever get a blocking messenger where a non-blocking one was expected. It can happen though. The static method newNonBlockingMessenger ensures that a messenger is not uselessly wrapped. Should anyone insist on it by using the constructor, it will still work regardless of the synchronicity of the wrapped messenger. <p/>A more important use of this class is to serve as a base for the VirtualMessenger that the Endpoint returns to invokers of getMessenger().<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>protected static long</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../net/jxta/impl/endpoint/AdaptorNonBlockingMessenger.html#THREAD_IDLE_DIE">THREAD_IDLE_DIE</A></B></CODE><BR> Amount of time that the service thread will wait for a message before idle expiring.</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>protected </CODE></FONT></TD><TD><CODE><B><A HREF="../../../../net/jxta/impl/endpoint/AdaptorNonBlockingMessenger.html#AdaptorNonBlockingMessenger(net.jxta.endpoint.EndpointAddress, net.jxta.endpoint.EndpointAddress, int, net.jxta.impl.endpoint.endpointMeter.OutboundMeter)">AdaptorNonBlockingMessenger</A></B>(<A HREF="../../../../net/jxta/endpoint/EndpointAddress.html" title="class in net.jxta.endpoint">EndpointAddress</A> dest, <A HREF="../../../../net/jxta/endpoint/EndpointAddress.html" title="class in net.jxta.endpoint">EndpointAddress</A> logicalDest, int qsize, <A HREF="../../../../net/jxta/impl/endpoint/endpointMeter/OutboundMeter.html" title="class in net.jxta.impl.endpoint.endpointMeter">OutboundMeter</A> messengerMeter)</CODE><BR> Create a new adaptor for the given destination with no permanent wrapped messager to back it.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> </CODE></FONT></TD><TD><CODE><B><A HREF="../../../../net/jxta/impl/endpoint/AdaptorNonBlockingMessenger.html#AdaptorNonBlockingMessenger(net.jxta.endpoint.Messenger, int)">AdaptorNonBlockingMessenger</A></B>(<A HREF="../../../../net/jxta/endpoint/Messenger.html" title="interface in net.jxta.endpoint">Messenger</A> wrapped, int qsize)</CODE><BR> Create a new adaptor non blocking messenger which wrapps the provided one permanently. </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/AdaptorNonBlockingMessenger.html#close()">close</A></B>()</CODE><BR> The permanently wrapped messenger is still there. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../../net/jxta/endpoint/EndpointAddress.html" title="class in net.jxta.endpoint">EndpointAddress</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../net/jxta/impl/endpoint/AdaptorNonBlockingMessenger.html#getLogicalDestinationAddress()">getLogicalDestinationAddress</A></B>()</CODE><BR> Returns the logical destination of this messenger.
