  97 A <a class="link" href="json-glib-JSON-Node.html#JsonNode" title="JsonNode"><span class="type">JsonNode</span></a> is a generic container of elements inside a JSON stream.
  98 It can contain fundamental types (integers, booleans, floating point
  99 numbers, strings) and complex types (arrays and objects).
 100 </p>
 101 <p>
 102 When parsing a JSON data stream you extract the root node and walk
 103 the node tree by retrieving the type of data contained inside the
 104 node with the <a class="link" href="json-glib-JSON-Node.html#JSON-NODE-TYPE:CAPS" title="JSON_NODE_TYPE()"><code class="literal">JSON_NODE_TYPE</code></a> macro. If the node contains a fundamental
 105 type you can retrieve a copy of the <span class="type">GValue</span> holding it with the
 106 <a class="link" href="json-glib-JSON-Node.html#json-node-get-value" title="json_node_get_value ()"><code class="function">json_node_get_value()</code></a> function, and then use the <span class="type">GValue</span> API to extract
 107 the data; if the node contains a complex type you can retrieve the
 108 <a class="link" href="json-glib-JSON-Object.html#JsonObject" title="JsonObject"><span class="type">JsonObject</span></a> or the <a class="link" href="json-glib-JSON-Array.html#JsonArray" title="JsonArray"><span class="type">JsonArray</span></a> using <a class="link" href="json-glib-JSON-Node.html#json-node-get-object" title="json_node_get_object ()"><code class="function">json_node_get_object()</code></a> or
