  87 <p>
  88 The GObject type system supports dynamic loading of types. The
  89 <a class="link" href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> interface is used to handle the lifecycle of
  90 dynamically loaded types.  It goes as follows:
  91 </p>
  92 <p>
  93 </p>
  94 <div class="orderedlist"><ol class="orderedlist" type="1">
  95 <li class="listitem">
  96 <p>
  97   The type is initially introduced (usually upon loading the module
  98   the first time, or by your main application that knows what modules
  99   introduces what types), like this:
 100   </p>
 101 <div class="informalexample"><pre class="programlisting">
 102   new_type_id = g_type_register_dynamic (parent_type_id,
 103                                                 "TypeName",
 104                                                 new_type_plugin,
 105                                                 type_flags);
 106   </pre></div>
 107 <p>
 108   where <code class="literal">new_type_plugin</code> is an implementation of the
 109   <a class="link" href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> interface.
 110 </p>
 111 </li>
 112 <li class="listitem"><p>
 113    The type's implementation is referenced, e.g. through
 114    <a class="link" href="gobject-Type-Information.html#g-type-class-ref" title="g_type_class_ref ()"><code class="function">g_type_class_ref()</code></a> or through <a class="link" href="gobject-Type-Information.html#g-type-create-instance" title="g_type_create_instance ()"><code class="function">g_type_create_instance()</code></a> (this is
 115    being called by <a class="link" href="gobject-The-Base-Object-Type.html#g-object-new" title="g_object_new ()"><code class="function">g_object_new()</code></a>) or through one of the above done on
 116    a type derived from <code class="literal">new_type_id</code>.
 117 </p></li>
 118 <li class="listitem"><p>
 119    This causes the type system to load the type's implementation by calling
 120    <a class="link" href="GTypePlugin.html#g-type-plugin-use" title="g_type_plugin_use ()"><code class="function">g_type_plugin_use()</code></a> and <a class="link" href="GTypePlugin.html#g-type-plugin-complete-type-info" title="g_type_plugin_complete_type_info ()"><code class="function">g_type_plugin_complete_type_info()</code></a> on
 121    <code class="literal">new_type_plugin</code>.
 122 </p></li>
 123 <li class="listitem"><p>
 124    At some point the type's implementation isn't required anymore, e.g. after
 125    <a class="link" href="gobject-Type-Information.html#g-type-class-unref" title="g_type_class_unref ()"><code class="function">g_type_class_unref()</code></a> or <a class="link" href="gobject-Type-Information.html#g-type-free-instance" title="g_type_free_instance ()"><code class="function">g_type_free_instance()</code></a> (called when the reference
 126    count of an instance drops to zero).
 127 </p></li>
 128 <li class="listitem"><p>
 129    This causes the type system to throw away the information retrieved from
 130    <a class="link" href="GTypePlugin.html#g-type-plugin-complete-type-info" title="g_type_plugin_complete_type_info ()"><code class="function">g_type_plugin_complete_type_info()</code></a> and then it calls
 131    <a class="link" href="GTypePlugin.html#g-type-plugin-unuse" title="g_type_plugin_unuse ()"><code class="function">g_type_plugin_unuse()</code></a> on <code class="literal">new_type_plugin</code>.
 132 </p></li>
 133 <li class="listitem"><p>
 134    Things may repeat from the second step.
 135 </p></li>
 136 </ol></div>
 137 <p>
 138 </p>
 139 <p>
 140 So basically, you need to implement a <a class="link" href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> type that
 141 carries a use_count, once use_count goes from zero to one, you need
 142 to load the implementation to successfully handle the upcoming
 143 <a class="link" href="GTypePlugin.html#g-type-plugin-complete-type-info" title="g_type_plugin_complete_type_info ()"><code class="function">g_type_plugin_complete_type_info()</code></a> call. Later, maybe after
 144 succeeding use/unuse calls, once use_count drops to zero, you can
 145 unload the implementation again. The type system makes sure to call
 146 <a class="link" href="GTypePlugin.html#g-type-plugin-use" title="g_type_plugin_use ()"><code class="function">g_type_plugin_use()</code></a> and <a class="link" href="GTypePlugin.html#g-type-plugin-complete-type-info" title="g_type_plugin_complete_type_info ()"><code class="function">g_type_plugin_complete_type_info()</code></a> again
 147 when the type is needed again.
 148 </p>
 149 <p>
 150 <a class="link" href="GTypeModule.html" title="GTypeModule"><span class="type">GTypeModule</span></a> is an implementation of <a class="link" href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> that already
 151 implements most of this except for the actual module loading and
 152 unloading. It even handles multiple registered types per module.
