public class Mount extends Interface
The `GMount` interface represents a user-visible mount, such as a mounted
file system.

`GMount` is a ‘mounted’ filesystem that you can access. Mounted is in
quotes because it’s not the same as a UNIX mount, it might be a GVFS
mount, but you can still access the files on it if you use GIO.

A `GMount` might be associated with a [iface@Gio.Volume] (such as a USB flash
drive) which hosts it.

Unmounting a `GMount` instance is an asynchronous operation. For
more information about asynchronous operations, see [iface@Gio.AsyncResult]
and [class@Gio.Task]. To unmount a `GMount` instance, first call
[method@Gio.Mount.unmount_with_operation] with (at least) the `GMount`
instance and a [type@Gio.AsyncReadyCallback]. The callback will be fired
when the operation has resolved (either with success or failure), and a
[iface@Gio.AsyncResult] structure will be passed to the callback. That
callback should then call [method@Gio.Mount.unmount_with_operation_finish]
with the `GMount` and the [iface@Gio.AsyncResult] data to see if the
operation was completed successfully. If an `error` is present when
[method@Gio.Mount.unmount_with_operation_finish] is called, then it will be
filled with any error information.

Note, when [porting from GnomeVFS](migrating-gnome-vfs.html), `GMount` is the
moral equivalent of `GnomeVFSVolume`.

    • getDefaultLocation

      public File getDefaultLocation()
      Gets the default location of @mount. The default location of the given
      @mount is a path that reflects the main entry point for the user (e.g.
      the home directory, or the root of the volume).

      This is a convenience method for getting the #GVolume and then
      using that object to get the #GDrive.
      Gibt zurück:
      a #GDrive or %NULL if @mount is not associated with a volume or a drive. The returned object should be unreffed with g_object_unref() when no longer needed.

    • getUuid

      public Str getUuid()
      Gets the UUID for the @mount. The reference is typically based on
      the file system UUID for the mount in question and should be
      considered an opaque string. Returns %NULL if there is no UUID
      available.
      Gibt zurück:
      the UUID for @mount or %NULL if no UUID can be computed. The returned string should be freed with g_free() when no longer needed.

    • guessContentType

      public void guessContentType(boolean force_rescan, @Nullable Cancellable cancellable, Mount.OnAsyncReadyCallback callback, @Nullable Pointer user_data)
      Tries to guess the type of content stored on @mount. Returns one or
      more textual identifiers of well-known content types (typically
      prefixed with "x-content/"), e.g. x-content/image-dcf for camera
      memory cards. See the
      [shared-mime-info](http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec)
      specification for more on x-content types.

      This is an asynchronous operation (see
      g_mount_guess_content_type_sync() for the synchronous version), and
      is finished by calling g_mount_guess_content_type_finish() with the
      @mount and #GAsyncResult data returned in the @callback.
      Parameter:
      force_rescan - Whether to force a rescan of the content. Otherwise a cached result will be used if available
      cancellable - optional #GCancellable object, %NULL to ignore
      callback - a #GAsyncReadyCallback
      user_data - user data passed to @callback

    • isShadowed

      public boolean isShadowed()
      Determines if @mount is shadowed. Applications or libraries should
      avoid displaying @mount in the user interface if it is shadowed.

      A mount is said to be shadowed if there exists one or more user
      visible objects (currently #GMount objects) with a root that is
      inside the root of @mount.

      One application of shadow mounts is when exposing a single file
      system that is used to address several logical volumes. In this
      situation, a #GVolumeMonitor implementation would create two
      #GVolume objects (for example, one for the camera functionality of
      the device and one for a SD card reader on the device) with
      activation URIs `gphoto2://[usb:001,002]/store1/`
      and `gphoto2://[usb:001,002]/store2/`. When the
      underlying mount (with root
      `gphoto2://[usb:001,002]/`) is mounted, said
      #GVolumeMonitor implementation would create two #GMount objects
      (each with their root matching the corresponding volume activation
      root) that would shadow the original mount.

      The proxy monitor in GVfs 2.26 and later, automatically creates and
      manage shadow mounts (and shadows the underlying mount) if the
      activation root on a #GVolume is set.
      Gibt zurück:
      %TRUE if @mount is shadowed.

    • remount

      public void remount(int flags, @Nullable MountOperation mount_operation, @Nullable Cancellable cancellable, Mount.OnAsyncReadyCallback callback, @Nullable Pointer user_data)
      Remounts a mount. This is an asynchronous operation, and is
      finished by calling g_mount_remount_finish() with the @mount
      and #GAsyncResults data returned in the @callback.

      Remounting is useful when some setting affecting the operation
      of the volume has been changed, as these may need a remount to
      take affect. While this is semantically equivalent with unmounting
      and then remounting not all backends might need to actually be
      unmounted.
      Parameter:
      flags - flags affecting the operation
      mount_operation - a #GMountOperation or %NULL to avoid user interaction.
      cancellable - optional #GCancellable object, %NULL to ignore.
      callback - a #GAsyncReadyCallback, or %NULL.
      user_data - user data passed to @callback.

    • remountFinish

      public boolean remountFinish(@Nonnull AsyncResult result) throws AllocationError
      Finishes remounting a mount. If any errors occurred during the operation,
      @error will be set to contain the errors and %FALSE will be returned.
      Parameter:
      result - a #GAsyncResult.
      Gibt zurück:
      %TRUE if the mount was successfully remounted. %FALSE otherwise.
      Löst aus:
      AllocationError

    • shadow

      public void shadow()
      Increments the shadow count on @mount. Usually used by
      #GVolumeMonitor implementations when creating a shadow mount for
      @mount, see g_mount_is_shadowed() for more information. The caller
      will need to emit the #GMount::changed signal on @mount manually.

      Unmounts a mount. This is an asynchronous operation, and is

      and #GAsyncResult data returned in the @callback.
      Parameter:
      flags - flags affecting the operation
      mount_operation - a #GMountOperation or %NULL to avoid user interaction.
