It requires that the <a href="Diagram.html#model" class="tsd-kind-accessor">Diagram.model</a> be serializable and deserializable using <a href="Model.html#toJson" class="tsd-kind-method">Model.toJson</a> and <a href="Model.html#fromJson" class="tsd-kind-method">Model.fromJson</a>.</p>
<p>As of version 3.1, the functionality is built into the <a href="CommandHandler.html" class="tsd-kind-class">CommandHandler</a> class.
Enable it by setting <a href="CommandHandler.html#storageLocation" class="tsd-kind-accessor">CommandHandler.storageLocation</a> to "localStorage".
However, the functionality is duplicated here for compatibility with versions earlier than 3.1.</p>
