Instance Method Details

#acquire(cancellable) ⇒ Boolean

Attempts to acquire the permission represented by permission.

The precise method by which this happens depends on the permission
and the underlying authentication mechanism. A simple example is
that a dialog may appear asking the user to enter their password.

You should check with g_permission_get_can_acquire() before calling
this function.

If the permission is acquired then true is returned. Otherwise,
false is returned and error is set appropriately.

This call is blocking, likely for a very long time (in the case that
user interaction is required). See g_permission_acquire_async() for
the non-blocking version.

Parameters:

• cancellable (Gio::Cancellable) —

  a #GCancellable, or nil

Returns:

• (Boolean) —

  true if the permission was successfully acquired

#acquire_async(cancellable, callback, user_data) ⇒ nil

Attempts to acquire the permission represented by permission.

This is the first half of the asynchronous version of
g_permission_acquire().

Parameters:

• cancellable (Gio::Cancellable) —

  a #GCancellable, or nil

• callback (Gio::AsyncReadyCallback) —

  the GAsync::ReadyCallback to call when done

• user_data (GObject) —

  the user data to pass to callback

Returns:

• (nil)

#acquire_finish(result) ⇒ Boolean

Collects the result of attempting to acquire the permission
represented by permission.

This is the second half of the asynchronous version of
g_permission_acquire().

Parameters:

• result (Gio::AsyncResult) —

  the GAsync::Result given to the #GAsyncReadyCallback

Returns:

• (Boolean) —

  true if the permission was successfully acquired

#allowed ⇒ Boolean

Gets the value of the 'allowed' property. This property is true if
the caller currently has permission to perform the action that
permission represents the permission to perform.

Returns:

• (Boolean) —

  the value of the 'allowed' property

#allowed=(allowed) ⇒ Boolean

true if the caller currently has permission to perform the action that
permission represents the permission to perform.

Parameters:

• allowed (Boolean)

Returns:

• (Boolean) —

  allowed

• (Boolean) —

  allowed

#allowed? ⇒ Boolean

true if the caller currently has permission to perform the action that
permission represents the permission to perform.

Returns:

• (Boolean) —

  allowed

#can_acquire ⇒ Boolean

Gets the value of the 'can-acquire' property. This property is true
if it is generally possible to acquire the permission by calling
g_permission_acquire().

Returns:

• (Boolean) —

  the value of the 'can-acquire' property

#can_acquire=(can_acquire) ⇒ Boolean

true if it is generally possible to acquire the permission by calling
g_permission_acquire().

Parameters:

• can_acquire (Boolean)

Returns:

• (Boolean) —

  can-acquire

• (Boolean) —

  can-acquire

#can_acquire? ⇒ Boolean

true if it is generally possible to acquire the permission by calling
g_permission_acquire().

Returns:

• (Boolean) —

  can-acquire

#can_release ⇒ Boolean

Gets the value of the 'can-release' property. This property is true
if it is generally possible to release the permission by calling
g_permission_release().

Returns:

• (Boolean) —

  the value of the 'can-release' property

#can_release=(can_release) ⇒ Boolean

true if it is generally possible to release the permission by calling
g_permission_release().

Parameters:

• can_release (Boolean)

Returns:

• (Boolean) —

  can-release

• (Boolean) —

  can-release

#can_release? ⇒ Boolean

true if it is generally possible to release the permission by calling
g_permission_release().

Returns:

• (Boolean) —

  can-release

#impl_update(allowed, can_acquire, can_release) ⇒ nil

This function is called by the #GPermission implementation to update
the properties of the permission. You should never call this
function except from a #GPermission implementation.

GObject notify signals are generated, as appropriate.

Parameters:

• allowed (Boolean) —

  the new value for the 'allowed' property

• can_acquire (Boolean) —

  the new value for the 'can-acquire' property

• can_release (Boolean) —

  the new value for the 'can-release' property

Returns:

• (nil)

#release(cancellable) ⇒ Boolean

Attempts to release the permission represented by permission.

The precise method by which this happens depends on the permission
and the underlying authentication mechanism. In most cases the
permission will be dropped immediately without further action.

You should check with g_permission_get_can_release() before calling
this function.

If the permission is released then true is returned. Otherwise,
false is returned and error is set appropriately.

This call is blocking, likely for a very long time (in the case that
user interaction is required). See g_permission_release_async() for
the non-blocking version.

Parameters:

• cancellable (Gio::Cancellable) —

  a #GCancellable, or nil

Returns:

• (Boolean) —

  true if the permission was successfully released

#release_async(cancellable, callback, user_data) ⇒ nil

Attempts to release the permission represented by permission.

This is the first half of the asynchronous version of
g_permission_release().

Parameters:

• cancellable (Gio::Cancellable) —

  a #GCancellable, or nil

• callback (Gio::AsyncReadyCallback) —

  the GAsync::ReadyCallback to call when done

• user_data (GObject) —

  the user data to pass to callback

Returns:

• (nil)

#release_finish(result) ⇒ Boolean

Collects the result of attempting to release the permission
represented by permission.

This is the second half of the asynchronous version of
g_permission_release().

Parameters:

• result (Gio::AsyncResult) —

  the GAsync::Result given to the #GAsyncReadyCallback

Returns:

• (Boolean) —

  true if the permission was successfully released
