Class Details¶
- class UDisks.Job¶
- Bases:
- Structure:
Abstract interface type for the D-Bus interface org.freedesktop.UDisks2.Job.
- classmethod interface_info()¶
- Returns:
A
Gio.DBusInterfaceInfo
. Do not free.- Return type:
Gets a machine-readable description of the org.freedesktop.UDisks2.Job D-Bus interface.
- classmethod override_properties(klass, property_id_begin)¶
- Parameters:
klass (
GObject.ObjectClass
) – The class structure for aGObject.Object
derived class.property_id_begin (
int
) – The property id to assign to the first overridden property.
- Returns:
The last property id.
- Return type:
Overrides all
GObject.Object
properties in theUDisks.Job
interface for a concrete class. The properties are overridden in the order they are defined.
- call_cancel(arg_options, cancellable, callback, *user_data)¶
- Parameters:
arg_options (
GLib.Variant
) – Argument to pass with the method invocation.cancellable (
Gio.Cancellable
orNone
) – AGio.Cancellable
orNone
.callback (
Gio.AsyncReadyCallback
orNone
) – AGio.AsyncReadyCallback
to call when the request is satisfied orNone
.
Asynchronously invokes the Cancel() D-Bus method on self. When the operation is finished, callback will be invoked in the thread-default main loop of the thread you are calling this method from (see
GLib.MainContext.push_thread_default
()). You can then callUDisks.Job.call_cancel_finish
() to get the result of the operation.See
UDisks.Job.call_cancel_sync
() for the synchronous, blocking version of this method.
- call_cancel_finish(res)¶
- Parameters:
res (
Gio.AsyncResult
) – TheGio.AsyncResult
obtained from theGio.AsyncReadyCallback
passed toUDisks.Job.call_cancel
().- Raises:
- Returns:
- Return type:
Finishes an operation started with
UDisks.Job.call_cancel
().
- call_cancel_sync(arg_options, cancellable)¶
- Parameters:
arg_options (
GLib.Variant
) – Argument to pass with the method invocation.cancellable (
Gio.Cancellable
orNone
) – AGio.Cancellable
orNone
.
- Raises:
- Returns:
- Return type:
Synchronously invokes the Cancel() D-Bus method on self. The calling thread is blocked until a reply is received.
See
UDisks.Job.call_cancel
() for the asynchronous version of this method.
- complete_cancel(invocation)¶
- Parameters:
invocation (
Gio.DBusMethodInvocation
) – AGio.DBusMethodInvocation
.
Helper function used in service implementations to finish handling invocations of the Cancel() D-Bus method. If you instead want to finish handling an invocation by returning an error, use g_dbus_method_invocation_return_error() or similar.
This method will free invocation, you cannot use it afterwards.
- emit_completed(arg_success, arg_message)¶
- Parameters:
Emits the “Completed” D-Bus signal.
- do_completed(arg_success, arg_message) virtual¶
-
Handler for the
UDisks.Job
::completed
signal.
- do_handle_cancel(invocation, arg_options) virtual¶
- Parameters:
invocation (
Gio.DBusMethodInvocation
) –arg_options (
GLib.Variant
) –
- Return type:
Handler for the
UDisks.Job
::handle-cancel
signal.
Signal Details¶
- UDisks.Job.signals.completed(job, arg_success, arg_message)¶
- Signal Name:
completed
- Flags:
- Parameters:
job (
UDisks.Job
) – The object which received the signalarg_success (
bool
) – Argument.arg_message (
str
) – Argument.
On the client-side, this signal is emitted whenever the D-Bus signal “Completed” is received.
On the service-side, this signal can be used with e.g. g_signal_emit_by_name() to make the object emit the D-Bus signal.
- UDisks.Job.signals.handle_cancel(job, invocation, arg_options)¶
- Signal Name:
handle-cancel
- Flags:
- Parameters:
job (
UDisks.Job
) – The object which received the signalinvocation (
Gio.DBusMethodInvocation
) – AGio.DBusMethodInvocation
.arg_options (
GLib.Variant
) – Argument passed by remote caller.
- Returns:
Gio.DBUS_METHOD_INVOCATION_HANDLED
orTrue
if the invocation was handled,Gio.DBUS_METHOD_INVOCATION_UNHANDLED
orFalse
to let other signal handlers run.- Return type:
Signal emitted when a remote caller is invoking the Cancel() D-Bus method.
If a signal handler returns
True
, it means the signal handler will handle the invocation (e.g. take a reference to invocation and eventually callUDisks.Job.complete_cancel
() or e.g. g_dbus_method_invocation_return_error() on it) and no other signal handlers will run. If no signal handler handles the invocation, theGio.DBusError.UNKNOWN_METHOD
error is returned.
Property Details¶
- UDisks.Job.props.bytes¶
-
Represents the D-Bus property “Bytes”.
Since the D-Bus property for this
GObject.Object
property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.
- UDisks.Job.props.cancelable¶
-
Represents the D-Bus property “Cancelable”.
Since the D-Bus property for this
GObject.Object
property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.
- UDisks.Job.props.expected_end_time¶
-
Represents the D-Bus property “ExpectedEndTime”.
