Data.GI.Base.Constructible
Description
Constructible types are those for which new is
defined. Often these are GObjects, but it is possible to
construct new (zero-initialized) structures and unions too.
Synopsis
- class Constructible a (tag :: AttrOpTag) where
- new :: MonadIO m => (ManagedPtr a -> a) -> [AttrOp a tag] -> m a
Documentation
class Constructible a (tag :: AttrOpTag) where Source #
Constructible types, i.e. those which can be allocated by new.
Methods
new :: MonadIO m => (ManagedPtr a -> a) -> [AttrOp a tag] -> m a Source #
Allocate a new instance of the given type, with the given attributes.
Instances
| (GObject a, tag ~ 'AttrConstruct) => Constructible a tag Source # | Default instance, assuming we have a |
