{- | Copyright : Will Thompson, Iñaki García Etxebarria and Jonas Platte License : LGPL-2.1 Maintainer : Iñaki García Etxebarria (garetxe@gmail.com) As of GLib 2.46, 'GI.Gio.Objects.SimpleAsyncResult.SimpleAsyncResult' is deprecated in favor of 'GI.Gio.Objects.Task.Task', which provides a simpler API. 'GI.Gio.Objects.SimpleAsyncResult.SimpleAsyncResult' implements 'GI.Gio.Interfaces.AsyncResult.AsyncResult'. GSimpleAsyncResult handles @/GAsyncReadyCallbacks/@, error reporting, operation cancellation and the final state of an operation, completely transparent to the application. Results can be returned as a pointer e.g. for functions that return data that is collected asynchronously, a boolean value for checking the success or failure of an operation, or a @/gssize/@ for operations which return the number of bytes modified by the operation; all of the simple return cases are covered. Most of the time, an application will not need to know of the details of this API; it is handled transparently, and any necessary operations are handled by 'GI.Gio.Interfaces.AsyncResult.AsyncResult'\'s interface. However, if implementing a new GIO module, for writing language bindings, or for complex applications that need better control of how asynchronous operations are completed, it is important to understand this functionality. GSimpleAsyncResults are tagged with the calling function to ensure that asynchronous functions and their finishing functions are used together correctly. To create a new 'GI.Gio.Objects.SimpleAsyncResult.SimpleAsyncResult', call 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultNew'. If the result needs to be created for a 'GError', use 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultNewFromError' or @/g_simple_async_result_new_take_error()/@. If a 'GError' is not available (e.g. the asynchronous operation\'s doesn\'t take a 'GError' argument), but the result still needs to be created for an error condition, use @/g_simple_async_result_new_error()/@ (or @/g_simple_async_result_set_error_va()/@ if your application or binding requires passing a variable argument list directly), and the error can then be propagated through the use of 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultPropagateError'. An asynchronous operation can be made to ignore a cancellation event by calling 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultSetHandleCancellation' with a 'GI.Gio.Objects.SimpleAsyncResult.SimpleAsyncResult' for the operation and 'False'. This is useful for operations that are dangerous to cancel, such as close (which would cause a leak if cancelled before being run). GSimpleAsyncResult can integrate into GLib\'s event loop, 'GI.GLib.Structs.MainLoop.MainLoop', or it can use @/GThreads/@. 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultComplete' will finish an I\/O task directly from the point where it is called. 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultCompleteInIdle' will finish it from an idle handler in the [thread-default main context][g-main-context-push-thread-default] where the 'GI.Gio.Objects.SimpleAsyncResult.SimpleAsyncResult' was created. @/g_simple_async_result_run_in_thread()/@ will run the job in a separate thread and then use 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultCompleteInIdle' to deliver the result. To set the results of an asynchronous function, @/g_simple_async_result_set_op_res_gpointer()/@, 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultSetOpResGboolean', and 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultSetOpResGssize' are provided, setting the operation\'s result to a gpointer, gboolean, or gssize, respectively. Likewise, to get the result of an asynchronous function, @/g_simple_async_result_get_op_res_gpointer()/@, 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultGetOpResGboolean', and 'GI.Gio.Objects.SimpleAsyncResult.simpleAsyncResultGetOpResGssize' are provided, getting the operation\'s result as a gpointer, gboolean, and gssize, respectively. For the details of the requirements implementations must respect, see 'GI.Gio.Interfaces.AsyncResult.AsyncResult'. A typical implementation of an asynchronous operation using GSimpleAsyncResult looks something like this: === /C code/ > >static void >baked_cb (Cake *cake, > gpointer user_data) >{ > // In this example, this callback is not given a reference to the cake, > // so the GSimpleAsyncResult has to take a reference to it. > GSimpleAsyncResult *result = user_data; > > if (cake == NULL) > g_simple_async_result_set_error (result, > BAKER_ERRORS, > BAKER_ERROR_NO_FLOUR, > "Go to the supermarket"); > else > g_simple_async_result_set_op_res_gpointer (result, > g_object_ref (cake), > g_object_unref); > > > // In this example, we assume that baked_cb is called as a callback from > // the mainloop, so it's safe to complete the operation synchronously here. > // If, however, _baker_prepare_cake () might call its callback without > // first returning to the mainloop — inadvisable, but some APIs do so — > // we would need to use g_simple_async_result_complete_in_idle(). > g_simple_async_result_complete (result); > g_object_unref (result); >} > >void >baker_bake_cake_async (Baker *self, > guint radius, > GAsyncReadyCallback callback, > gpointer user_data) >{ > GSimpleAsyncResult *simple; > Cake *cake; > > if (radius < 3) > { > g_simple_async_report_error_in_idle (G_OBJECT (self), > callback, > user_data, > BAKER_ERRORS, > BAKER_ERROR_TOO_SMALL, > "%ucm radius cakes are silly", > radius); > return; > } > > simple = g_simple_async_result_new (G_OBJECT (self), > callback, > user_data, > baker_bake_cake_async); > cake = _baker_get_cached_cake (self, radius); > > if (cake != NULL) > { > g_simple_async_result_set_op_res_gpointer (simple, > g_object_ref (cake), > g_object_unref); > g_simple_async_result_complete_in_idle (simple); > g_object_unref (simple); > // Drop the reference returned by _baker_get_cached_cake(); > // the GSimpleAsyncResult has taken its own reference. > g_object_unref (cake);
