<span class="versionnote">New in version 2.4.</span>
<P>
In <a class="url" href="http://www.xmlrpc.com/discuss/msgReader%241208">http://www.xmlrpc.com/discuss/msgReader%241208</a>, an approach
is presented to encapsulate multiple calls to a remote server into a
single request.
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
<td><nobr><b><span class="typelabel">class</span> <tt id='l2h-3714' xml:id='l2h-3714' class="class">MultiCall</tt></b>(</nobr></td>
<td><var>server</var>)</td></tr></table></dt>
<dd>
<P>
Create an object used to boxcar method calls. <var>server</var> is the
eventual target of the call. Calls can be made to the result object,
but they will immediately return <var>None</var>, and only store the
call name and parameters in the <tt class="class">MultiCall</tt> object. Calling
the object itself causes all stored calls to be transmitted as
a single <code>system.multicall</code> request. The result of this call
is a generator; iterating over this generator yields the individual
results.
<P>
</dl>
<P>
A usage example of this class is
