Its main purpose is to provide references to the documentation needed in order to create conforming implementations of that specification. A secondary use is, optionaly, to make running instances usable remotely, by publishing any or all of the following:<br> <ul> <li> PipeAdvertisement <li> ModuleSpecID of a proxy module <li> ModuleSpecID of an authenticator module </ul> Not all modules are usable remotely, it is up to the specification creator to make that choice. However, if the specification dictates it, all implementations can be expected to support it. <p> Note that the Standard PeerGroup implementation of the java reference implementation does <em>not</em> support replacing a group service with a pipe to a remote instance. However, nothing prevents a particular implementation of a group from using a proxy module in place of the fully version; provided that the API (and therefore the ClassIDs) of the proxy and local versions are identical. <p> Note also that in the case of the local+proxy style, it is up to the implementation of both sides to figure-out which pipe to listen to or connect to. The safest method is probably for the full version to seek its own ModuleSpecAdvertisement, and for the proxy version to accept the full version's ModuleSpecAdvertisement as a paramter. Alternatively if the proxy version is completely dedicated to the specification that it proxies, both sides may have the PipeID and type hardcoded.<P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../net/jxta/platform/ModuleSpecID.html" title="class in net.jxta.platform"><CODE>ModuleSpecID</CODE></A>, <A HREF="../../../net/jxta/protocol/PipeAdvertisement.html" title="class in net.jxta.protocol"><CODE>PipeAdvertisement</CODE></A>, <A HREF="../../../net/jxta/protocol/ModuleImplAdvertisement.html" title="class in net.jxta.protocol"><CODE>ModuleImplAdvertisement</CODE></A>, <A HREF="../../../net/jxta/document/Advertisement.html" title="class in net.jxta.document"><CODE>Advertisement</CODE></A></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== 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><CODE><B><A HREF="../../../net/jxta/protocol/ModuleSpecAdvertisement.html#ModuleSpecAdvertisement()">ModuleSpecAdvertisement</A></B>()</CODE><BR> </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> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/protocol/ModuleSpecAdvertisement.html#clone()">clone</A></B>()</CODE><BR> Clone this ModuleSpecAdvertisement</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/protocol/ModuleSpecAdvertisement.html#getAdvertisementType()">getAdvertisementType</A></B>()</CODE><BR> {@inheritDoc}</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../net/jxta/platform/ModuleSpecID.html" title="class in net.jxta.platform">ModuleSpecID</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/protocol/ModuleSpecAdvertisement.html#getAuthSpecID()">getAuthSpecID</A></B>()</CODE><BR> returns the specID of an authenticator module.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/protocol/ModuleSpecAdvertisement.html#getBaseAdvType()">getBaseAdvType</A></B>()</CODE><BR> Returns the base type of this advertisement hierarchy.
