The <a href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> interface is used to handle the lifecycle of dynamically loaded types. It goes as follows: </p><p> </p><div class="orderedlist"><ol type="1"><li><p> The type is initially introduced (usually upon loading the module the first time, or by your main application that knows what modules introduces what types), like this: <tt class="literal">new_type_id = g_type_register_dynamic (parent_type_id, "TypeName", new_type_plugin, type_flags); </tt> where <tt class="literal">new_type_plugin</tt> is an implementation of the <a href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> interface. </p></li><li><p> The type's implementation is referenced, e.g. through <a href="gobject-Type-Information.html#g-type-class-ref"><tt class="function">g_type_class_ref()</tt></a> or through <a href="gobject-Type-Information.html#g-type-create-instance"><tt class="function">g_type_create_instance()</tt></a> (this is being called by <a href="gobject-The-Base-Object-Type.html#g-object-new"><tt class="function">g_object_new()</tt></a>) or through one of the above done on a type derived from <tt class="literal">new_type_id</tt>. </p></li><li><p> This causes the type system to load the type's implementation by calling <a href="GTypePlugin.html#g-type-plugin-use"><tt class="function">g_type_plugin_use()</tt></a> and <a href="GTypePlugin.html#g-type-plugin-complete-type-info"><tt class="function">g_type_plugin_complete_type_info()</tt></a> on <tt class="literal">new_type_plugin</tt>. </p></li><li><p> At some point the type's implementation isn't required anymore, e.g. after <a href="gobject-Type-Information.html#g-type-class-unref"><tt class="function">g_type_class_unref()</tt></a> or <a href="gobject-Type-Information.html#g-type-free-instance"><tt class="function">g_type_free_instance()</tt></a> (called when the reference count of an instance drops to zero). </p></li><li><p> This causes the type system to throw away the information retrieved from <a href="GTypePlugin.html#g-type-plugin-complete-type-info"><tt class="function">g_type_plugin_complete_type_info()</tt></a> and then it calls <a href="GTypePlugin.html#g-type-plugin-unuse"><tt class="function">g_type_plugin_unuse()</tt></a> on <tt class="literal">new_type_plugin</tt>. </p></li><li><p> Things may repeat from the second step. </p></li></ol></div><p> </p><p> So basically, you need to implement a <a href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> type that carries a use_count, once use_count goes from zero to one, you need to load the implementation to successfully handle the upcoming <a href="GTypePlugin.html#g-type-plugin-complete-type-info"><tt class="function">g_type_plugin_complete_type_info()</tt></a> call. Later, maybe after succeeding use/unuse calls, once use_count drops to zero, you can unload the implementation again. The type system makes sure to call <a href="GTypePlugin.html#g-type-plugin-use"><tt class="function">g_type_plugin_use()</tt></a> and <a href="GTypePlugin.html#g-type-plugin-complete-type-info"><tt class="function">g_type_plugin_complete_type_info()</tt></a> again when the type is needed again. </p><p> <a href="GTypeModule.html" title="GTypeModule"><span class="type">GTypeModule</span></a> is an implementation of <a href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> that already implements most of this except for the actual module loading and unloading. It even handles multiple registered types per module. </p></div><div class="refsect1" lang="en"><a name="id2779474"></a><h2>Details</h2><div class="refsect2" lang="en"><a name="id2779480"></a><h3><a name="GTypePlugin-struct"></a>struct GTypePlugin</h3><a class="indexterm" name="id2779490"></a><pre class="programlisting">struct GTypePlugin;</pre><p> The <span class="structname">GTypePlugin</span> typedef is used as a placeholder for objects that implement the <span class="structname">GTypePlugin</span> interface. </p></div><hr><div class="refsect2" lang="en"><a name="id2779514"></a><h3><a name="GTypePluginClass"></a>struct GTypePluginClass</h3><a class="indexterm" name="id2779525"></a><pre class="programlisting">struct GTypePluginClass { GTypePluginUse use_plugin; GTypePluginUnuse unuse_plugin; GTypePluginCompleteTypeInfo complete_type_info; GTypePluginCompleteInterfaceInfo complete_interface_info; }; </pre><p> The <a href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> interface is used by the type system in order to handle the lifecycle of dynamically loaded types. </p><div class="variablelist"><table border="0"><col align="left" valign="top"><tbody><tr><td><span class="term"><a href="GTypePlugin.html#GTypePluginUse">GTypePluginUse</a> <i class="structfield"><tt>use_plugin</tt></i></span></td><td>Increases the use count of the plugin. </td></tr><tr><td><span class="term"><a href="GTypePlugin.html#GTypePluginUnuse">GTypePluginUnuse</a> <i class="structfield"><tt>unuse_plugin</tt></i></span></td><td>Decreases the use count of the plugin. </td></tr><tr><td><span class="term"><a href="GTypePlugin.html#GTypePluginCompleteTypeInfo">GTypePluginCompleteTypeInfo</a> <i class="structfield"><tt>complete_type_info</tt></i></span></td><td>Fills in the <a href="gobject-Type-Information.html#GTypeInfo"><span class="type">GTypeInfo</span></a> and <a href="gobject-Type-Information.html#GTypeValueTable"><span class="type">GTypeValueTable</span></a> structs for the type.
