DynamicTypeFactory
is used to represent a type that can be
automatically loaded the first time it is used. For example,
a non-standard type for use in caps fields.
In general, applications and plugins don't need to use the factory beyond registering the type in a plugin init function. Once that is done, the type is stored in the registry, and ready as soon as the registry is loaded.
Registering a type for dynamic loading
C code
static gboolean plugin_init (GstPlugin * plugin) { return gst_dynamic_type_register (plugin, GST_TYPE_CUSTOM_CAPS_FIELD); }
- newtype DynamicTypeFactory = DynamicTypeFactory (ManagedPtr DynamicTypeFactory)
- class GObject o => IsDynamicTypeFactory o
- toDynamicTypeFactory :: (MonadIO m, IsDynamicTypeFactory o) => o -> m DynamicTypeFactory
- noDynamicTypeFactory :: Maybe DynamicTypeFactory
- dynamicTypeFactoryLoad :: (HasCallStack, MonadIO m) => Text -> m GType
