<h2 id="details">Detailed Description</h2>
<p>The Node type provides an entry point to a Qt Remote Objects network. A network can be as simple as two nodes, or an arbitrarily complex set of processes and devices.</p>
<p>A Node does not have a url that other nodes can connect to, and thus is able to acquire replicas only. It is not able to share source objects.</p>

</div><div class="qmldoc"><p>Heartbeat interval in ms.</p>
<p>The heartbeat (only helpful for socket connections) will periodically send a message to connected nodes to detect whether the connection was disrupted. Qt Remote Objects will try to reconnect automatically if it detects a dropped connection. This function can help with that detection since the client will only detect that the server is unavailable when it tries to send data.</p>
<p>A value of <code>0</code> (the default) will disable the heartbeat.</p>
