Optionalproperties: Partial<Flatpak.Installation.ConstructorProps>Adds a new remote object to the set of remotes. This is similar
to flatpak_installation_modify_remote() for non-existing remote
names. However, if the named remote already exists then instead of
modifying it it fails with Flatpak.Error.ALREADY_INSTALLED, or if
if_needed is true it silently succeeds without doing anything.
As an exception to the last, if the local config has a filter defined,
but the new remote unsets the filter (for example, it comes from an
unfiltered .flatpakref via flatpak_remote_new_from_file()) the the local
remote filter gets reset. This is to allow the setup where there is a
default setup of a filtered remote, yet you can still use the standard
flatpakref file to get the full contents without getting two remotes.

Optionalcancellable: Gio.Cancellabletrue if the modifications have been committed successfully
Remove all OSTree refs from the local flatpak repository which are not
in a deployed state. The next time the underlying OSTree repo is pruned,
objects which were attached to that ref will be removed. This is useful if
you pulled a flatpak refs using flatpak_installation_install_full() and
specified Flatpak.InstallFlags.NO_DEPLOY but then decided not to
deploy the refs later on and want to remove the local refs to prevent them
from taking up disk space. Note that this will not remove the objects
referred to by ref from the underlying OSTree repo, you should use
flatpak_installation_prune_local_repo() to do that.

Install a new application or runtime.
Note that this function was originally written to always return a Flatpak.InstalledRef. Since 0.9.13, passing FLATPAK_INSTALL_FLAGS_NO_DEPLOY will only pull refs into the local flatpak repository without deploying them, however this function will be unable to provide information on the installed ref, so FLATPAK_ERROR_ONLY_PULLED will be set and the caller must respond accordingly.

Creates a remote based on the passed in .flatpakref file contents
in ref_file_data and returns the Flatpak.RemoteRef that can be used
to install it.
Note, the Flatpak.RemoteRef will not have the commit field set, or other details, to avoid unnecessary roundtrips. If you need that you have to resolve it explicitly with flatpak_installation_fetch_remote_ref_sync ().

Optionalcancellable: Gio.Cancellablea GPtrArray of Flatpak.InstalledRef instances
Lists the installed apps and runtimes that have an update available, either
from the configured remote or locally available but not deployed (see
flatpak_transaction_set_no_deploy()).
This also checks if any of Flatpak.InstalledRef has a missing Flatpak.RelatedRef
(which has should-download set to true) or runtime. If so, it adds the
ref to the returning GLib.PtrArray to pull in the Flatpak.RelatedRef or runtime
again via an update operation in Flatpak.Transaction.
In case more than one app needs an update of the same runtime or extension, this function will return all of those apps.
Optionalcancellable: Gio.Cancellablea GPtrArray of Flatpak.InstalledRef instances, or null on error
Lists all the locally installed refs that are related to ref. These are
things that are interesting to install, update, or uninstall together with
ref. For instance, locale data or debug information.
Note that while the related refs are usually installed from the same remote
as ref (remote_name), it is possible they were installed from another
remote.
This function is similar to flatpak_installation_list_remote_related_refs_sync, but instead of looking at what is available on the remote, it only looks at the locally installed refs. This is useful for instance when you're looking for related refs to uninstall, or when you're planning to use FLATPAK_UPDATE_FLAGS_NO_PULL to install previously pulled refs.

Optionalcancellable: Gio.Cancellablea GPtrArray of Flatpak.RelatedRef instances
Lists the installed references that are pinned, meaning they will not be

Optionalcancellable: Gio.Cancellablea GPtrArray of Flatpak.RemoteRef instances
Lists all the available refs on remote_name that are related to ref, and
which are appropriate for the installed version of ref. For example if the
installed version of org.videolan.VLC has a related ref of
org.videolan.VLC.Plugin.bdj//3-19.08 and the remote version of VLC has a
related ref of org.videolan.VLC.Plugin.bdj//3-20.08, this function will only
return the 3-19.08 branch.
See also the related functions
flatpak_installation_list_remote_related_refs_sync() and
flatpak_installation_list_installed_related_refs_sync().
The returned list contains all available related refs, but not
every one should always be installed. For example,
flatpak_related_ref_should_download() returns true if the
reference should be installed/updated with the app, and
flatpak_related_ref_should_delete() returns true if it
should be uninstalled with the main ref.
The commit property of each Flatpak.RelatedRef is not guaranteed to be
non-null.

Optionalcancellable: Gio.Cancellablea GPtrArray of Flatpak.Remote instances
Lists the installed references that are not 'used'.
A reference is used if it is either an application,

Optionalcancellable: Gio.Cancellabletrue on success
Remove the OSTree ref given by remote_name:ref from the local flatpak

which were attached to that ref will be removed. This is useful if you
pulled a flatpak ref using flatpak_installation_install_full() and
specified Flatpak.InstallFlags.NO_DEPLOY but then decided not to
deploy the ref later on and want to remove the local ref to prevent it
from taking up disk space. Note that this will not remove the objects

Staticnew_Optionalcancellable: Gio.CancellableStaticnew_Optionalcancellable: Gio.CancellableStaticnew_Optionalid: stringOptionalcancellable: Gio.CancellableStaticnew_Optionalcancellable: Gio.CancellableCreates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget GObject.Object instance to be updated with the same value of the "active" property of the action GObject.Object instance.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
GObject.Binding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.

Creates a binding between source_property on source and target_property

the binding.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well. The transform_from function is only used in case
of bidirectional bindings, otherwise it will be ignored
The binding will automatically be removed when either the source or the
target instances are finalized. This will release the reference that is
being held on the GObject.Binding instance; if you want to hold on to the
GObject.Binding instance, you will need to hold a reference to it.
To remove the binding, call g_binding_unbind().
A GObject.Object can have multiple bindings.
The same user_data parameter will be used for both transform_to
and transform_from transformation functions; the notify function will
be called once, when the binding is removed. If you need different data

This function is intended for GObject.Object implementations to re-enforce
a [floating][floating-ref] object reference. Doing this is seldom
required: all GInitiallyUnowneds are created with a floating reference
which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
GObject.Object::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Gets a named field from the objects table of associations (see g_object_set_data()).

Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than
g_object_notify().
One way to avoid using g_object_notify() from within the
class that registered the properties, and using g_object_notify_by_pspec()
instead, is to store the GParamSpec used with
g_object_class_install_property() inside a static array, e.g.:
typedef enum
{
PROP_FOO = 1,
PROP_LAST
} MyObjectProperty;
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", NULL, NULL,
0, 100,
50,
G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the GObject.ParamSpec of a property installed on the class of object.
Increases the reference count of object.
Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type
of object will be propagated to the return type (using the GCC typeof()
extension), so any casting the caller needs to do on the return type must be
explicit.
the same object
Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
object
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.
Object containing the properties to set
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a GLib.Quark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the GLib.Quark storage growing unbounded.

the data if found, or null if no such data exists.
This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of
g_object_steal_qdata() would have left the destroy function set,
and thus the partial string list would have been freed upon
g_object_set_qdata_full().

Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one GObject.Object::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.

Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the GObject.Object may be reused in future (for example, if it is
an instance variable of another object), it is recommended to clear the
pointer to null rather than retain a dangling pointer to a potentially
invalid GObject.Object instance. Use g_clear_object() for this.
Virtualvfunc_the constructed function is called by g_object_new() as the
final step of the object creation process. At the point of the call, all
construction properties have been set on the object. The purpose of this
call is to allow for object initialisation steps that can only be performed
after construction properties have been set. constructed implementors
should chain up to the constructed call of their parent class to allow it
to complete its initialisation.
Virtualvfunc_Virtualvfunc_the dispose function is supposed to drop all references to other
objects, but keep the instance otherwise intact, so that client method
invocations still work. It may be run multiple times (due to reference
loops). Before returning, dispose should chain up to the dispose method
of the parent class.
Virtualvfunc_instance finalization function, should finish the finalization of
the instance begun in dispose and chain up to the finalize method of the
parent class.
Virtualvfunc_Virtualvfunc_Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
Virtualvfunc_the generic setter for all properties of this type. Should be
overridden for every type with properties. If implementations of
set_property don't emit property change notification explicitly, this will
be done implicitly by the type system. However, if the notify signal is
emitted explicitly, the type system will not emit it a second time.
This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

Staticinterface_Add a property to an interface; this is only useful for interfaces
that are added to GObject-derived types. Adding a property to an
interface forces all objects classes with that interface to have a
compatible property. The compatible property could be a newly
created GObject.ParamSpec, but normally
g_object_class_override_property() will be used so that the object
class only needs to provide an implementation and inherits the
property description, default value, bounds, and so forth from the
interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
GObject.TypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.
