GI.Gst.Objects.DynamicTypeFactory
Contents
Description
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);
}Since: 1.12
Synopsis
- newtype DynamicTypeFactory = DynamicTypeFactory (ManagedPtr DynamicTypeFactory)
- class (GObject o, IsDescendantOf DynamicTypeFactory o) => IsDynamicTypeFactory o
- toDynamicTypeFactory :: (MonadIO m, IsDynamicTypeFactory o) => o -> m DynamicTypeFactory
- dynamicTypeFactoryLoad :: (HasCallStack, MonadIO m) => Text -> m GType
Exported types
newtype DynamicTypeFactory Source #
Memory-managed wrapper type.
Constructors

Instances
class (GObject o, IsDescendantOf DynamicTypeFactory o) => IsDynamicTypeFactory o Source #
Type class for types which can be safely cast to DynamicTypeFactory, for instance with toDynamicTypeFactory.
Instances
| (GObject o, IsDescendantOf DynamicTypeFactory o) => IsDynamicTypeFactory o Source # | |

toDynamicTypeFactory :: (MonadIO m, IsDynamicTypeFactory o) => o -> m DynamicTypeFactory Source #
Cast to DynamicTypeFactory, for types for which this is known to be safe. For general casts, use castTo.
