<p>Gateway id conversion forms a gateway between different <a href="../DRb.html"><code>DRb</code></a> protocols or networks.</p>
<p>The gateway needs to install this id conversion and create servers for each of the protocols or networks it will be a gateway between. It then needs to create a server that attaches to each of these networks. For example:</p>
<pre class="ruby"><span class="ruby-identifier">require</span> <span class="ruby-string">'drb/drb'</span>
<span class="ruby-identifier">require</span> <span class="ruby-string">'drb/unix'</span>
<span class="ruby-identifier">require</span> <span class="ruby-string">'drb/gw'</span>
<span class="ruby-constant">DRb</span>.<span class="ruby-identifier">install_id_conv</span> <span class="ruby-constant">DRb</span><span class="ruby-operator">::</span><span class="ruby-constant">GWIdConv</span>.<span class="ruby-identifier">new</span>
<span class="ruby-identifier">gw</span> = <span class="ruby-constant">DRb</span><span class="ruby-operator">::</span><span class="ruby-constant">GW</span>.<span class="ruby-identifier">new</span>
<span class="ruby-identifier">s1</span> = <span class="ruby-constant">DRb</span><span class="ruby-operator">::</span><span class="ruby-constant">DRbServer</span>.<span class="ruby-identifier">new</span> <span class="ruby-string">'drbunix:/path/to/gateway'</span>, <span class="ruby-identifier">gw</span>
<span class="ruby-identifier">s2</span> = <span class="ruby-constant">DRb</span><span class="ruby-operator">::</span><span class="ruby-constant">DRbServer</span>.<span class="ruby-identifier">new</span> <span class="ruby-string">'druby://example:10000'</span>, <span class="ruby-identifier">gw</span>
<span class="ruby-identifier">s1</span>.<span class="ruby-identifier">thread</span>.<span class="ruby-identifier">join</span>
<span class="ruby-identifier">s2</span>.<span class="ruby-identifier">thread</span>.<span class="ruby-identifier">join</span>
</pre>
<p>Each client must register services with the gateway, for example:</p>
<pre class="ruby"><span class="ruby-constant">DRb</span>.<span class="ruby-identifier">start_service</span> <span class="ruby-string">'drbunix:'</span>, <span class="ruby-keyword">nil</span> <span class="ruby-comment"># an anonymous server</span>
<span class="ruby-identifier">gw</span> = <span class="ruby-constant">DRbObject</span>.<span class="ruby-identifier">new</span> <span class="ruby-keyword">nil</span>, <span class="ruby-string">'drbunix:/path/to/gateway'</span>
<span class="ruby-identifier">gw</span>[<span class="ruby-value">:unix</span>] = <span class="ruby-identifier">some_service</span>
<span class="ruby-constant">DRb</span>.<span class="ruby-identifier">thread</span>.<span class="ruby-identifier">join</span>
