class: ContentSerializer

[18:7] extends: object

Serializes content for inter-application data transfers. The GdkContentSerializer transforms an object that is identified by a GType into a serialized form (i.e. a byte stream) that is identified by a mime type. GTK provides serializers and deserializers for common data types such as text, colors, images or file lists. To register your own serialization functions, use [func@Gdk.content_register_serializer]. Also see [class@Gdk.ContentDeserializer].

Methods

• ContentSerializer (Handle = null)

  Creates a new ContentSerializer by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asObject ()

  Wraps this handle as Object.

  • @r A Object object.

• asAsyncResult ()

  Wraps this handle as AsyncResult.

  • @r A AsyncResult object.

• get_cancellable ()

  Gets the cancellable for the current operation. This is the GCancellable that was passed to [func@content_serialize_async].

• get_mime_type ()

  Gets the mime type to serialize to.

• get_output_stream ()

  Gets the output stream for the current operation. This is the stream that was passed to [func@content_serialize_async].

• get_priority ()

  Gets the I/O priority for the current operation. This is the priority that was passed to [func@content_serialize_async].

• get_task_data ()

  Gets the data that was associated with the current operation. See [method@Gdk.ContentSerializer.set_task_data].

• get_user_data ()

  Gets the user data that was passed when the serializer was registered.

• get_value ()

  Gets the GValue to read the object to serialize from.

• return_error (object error)

  Indicate that the serialization has ended with an error. This function consumes @error.

  • @p error is a GError.
  • @r None.

• return_success ()

  Indicate that the serialization has been successfully completed.

  • @r None.
