The model of #GTypeModule is a dynamically loaded module 38 * which implements some number of types and interface implementations. 39 * When the module is loaded, it registers its types and interfaces 40 * using g_type_module_register_type() and g_type_module_add_interface(). 41 * As long as any instances of these types and interface implementations 42 * are in use, the module is kept loaded. When the types and interfaces 43 * are gone, the module may be unloaded. If the types and interfaces 44 * become used again, the module will be reloaded. Note that the last 45 * unref cannot happen in module code, since that would lead to the 46 * caller's code being unloaded before g_object_unref() returns to it. 47 * 48 * Keeping track of whether the module should be loaded or not is done by 49 * using a use count - it starts at zero, and whenever it is greater than 50 * zero, the module is loaded. The use count is maintained internally by 51 * the type system, but also can be explicitly controlled by 52 * g_type_module_use() and g_type_module_unuse(). Typically, when loading 53 * a module for the first type, g_type_module_use() will be used to load 54 * it so that it can initialize its types. At some later point, when the 55 * module no longer needs to be loaded except for the type 56 * implementations it contains, g_type_module_unuse() is called. 57 * 58 * #GTypeModule does not actually provide any implementation of module 59 * loading and unloading. To create a particular module type you must 60 * derive from #GTypeModule and implement the load and unload functions 61 * in #GTypeModuleClass. 62 */ 63 public class TypeModule : ObjectG, TypePluginIF 64 { 65 /** the main Gtk struct */ 66 protected GTypeModule* gTypeModule; 67 68 /** Get the main Gtk struct */ 69 public GTypeModule* getTypeModuleStruct(bool transferOwnership = false) 70 { 71 if (transferOwnership) 72 ownedRef = false; 73 return gTypeModule; 74 } 75 76 /** the main Gtk struct as a void* */ 77 protected override void* getStruct() 78 { 79 return cast(void*)gTypeModule; 80 } 81 82 protected override void setStruct(GObject* obj) 83 { 84 gTypeModule = cast(GTypeModule*)obj; 85 super.setStruct(obj); 86 } 87 88 /** 89 * Sets our main struct and passes it to the parent class. 90 */ 91 public this (GTypeModule* gTypeModule, bool ownedRef = false) 92 { 93 this.gTypeModule = gTypeModule; 94 super(cast(GObject*)gTypeModule, ownedRef); 95 } 96 97 // add the TypePlugin capabilities 98 mixin TypePluginT!(GTypeModule); 99 100 101 /** */ 102 public static GType getType() 103 { 104 return g_type_module_get_type(); 105 } 106 107 /** 108 * Registers an additional interface for a type, whose interface lives 109 * in the given type plugin.
