Description

A GdkContentSerializer is used to serialize content for inter-application data transfers.

Functions

GdkContentSerializeFunc ()

void
(*GdkContentSerializeFunc) (GdkContentSerializer *serializer);

The type of a function that can be registered with gdk_content_register_serializer(). When the function gets called to operate on content, it can call functions on the serializer object to obtain the mime type, output stream, user data, etc. for its operation.

Parameters

serializer

a GdkContentSerializer

  

gdk_content_serializer_get_mime_type ()

const char *
gdk_content_serializer_get_mime_type (GdkContentSerializer *serializer);

Gets the mime type to serialize to.

Parameters

serializer

a GdkContentSerializer

  

Returns

the mime type for the current operation.

[transfer none]

gdk_content_serializer_get_gtype ()

GType
gdk_content_serializer_get_gtype (GdkContentSerializer *serializer);

Gets the GType to of the object to serialize.

Parameters

serializer

a GdkContentSerializer

  

Returns

the GType for the current operation

gdk_content_serializer_get_value ()

const GValue *
gdk_content_serializer_get_value (GdkContentSerializer *serializer);

Gets the GValue to read the object to serialize from.

Parameters

serializer

a GdkContentSerializer

  

Returns

the GValue for the current operation.

[transfer none]

gdk_content_serializer_get_output_stream ()

GOutputStream *
gdk_content_serializer_get_output_stream
                               (GdkContentSerializer *serializer);

Gets the output stream that was passed to gdk_content_serialize_async().

Parameters

serializer

a GdkContentSerializer

  

Returns

the output stream for the current operation.

[transfer none]

gdk_content_serializer_get_priority ()

int
gdk_content_serializer_get_priority (GdkContentSerializer *serializer);

Gets the io priority that was passed to gdk_content_serialize_async().

Parameters

serializer

a GdkContentSerializer

  

Returns

the io priority for the current operation

gdk_content_serializer_get_cancellable ()

GCancellable *
gdk_content_serializer_get_cancellable
                               (GdkContentSerializer *serializer);

Gets the cancellable that was passed to gdk_content_serialize_async().

Parameters

serializer

a GdkContentSerializer

  

Returns

the cancellable for the current operation.

[transfer none]

gdk_content_serializer_get_user_data ()

gpointer
gdk_content_serializer_get_user_data (GdkContentSerializer *serializer);

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

Parameters

serializer

a GdkContentSerializer

  

Returns

the user data for this serializer.

[transfer none]

gdk_content_serializer_set_task_data ()

void
gdk_content_serializer_set_task_data (GdkContentSerializer *serializer,
                                      gpointer data,
                                      GDestroyNotify notify);

Associate data with the current serialization operation.

Parameters

serializer

a GdkContentSerializer

  

data

data to associate with this operation

  

notify

destroy notify for data

 

gdk_content_serializer_get_task_data ()

gpointer
gdk_content_serializer_get_task_data (GdkContentSerializer *serializer);

Gets the data that was associated with serializer via gdk_content_serializer_set_task_data().

Parameters

serializer

a GdkContentSerializer

  

Returns

the task data for serializer .

[transfer none]

gdk_content_serializer_return_success ()

void
gdk_content_serializer_return_success (GdkContentSerializer *serializer);

Indicate that the serialization has been successfully completed.

Parameters

serializer

a GdkContentSerializer

  

gdk_content_serializer_return_error ()

void
gdk_content_serializer_return_error (GdkContentSerializer *serializer,
                                     GError *error);

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

Parameters

serializer

a GdkContentSerializer

  

error

a GError

  

gdk_content_register_serializer ()

void
gdk_content_register_serializer (GType type,
                                 const char *mime_type,
                                 GdkContentSerializeFunc serialize,
                                 gpointer data,
                                 GDestroyNotify notify);

Registers a function to convert objects of the given type to a serialized representation with the given mime type.

Parameters

type

the type of objects that the function can serialize

  

mime_type

the mime type to serialize to

  

serialize

the callback

  

data

data that serialize can access

  

notify

destroy notify for data

 

gdk_content_serialize_async ()

void
gdk_content_serialize_async (GOutputStream *stream,
                             const char *mime_type,
                             const GValue *value,

                             gpointer user_data);

Serialize content and write it to the given output stream, asynchronously. When the operation is finished, callback will be called. You can then call gdk_content_serialize_finish() to get the result of the operation.

Parameters

stream

a GOutputStream to write the serialized content to

  

mime_type

the mime type to serialize to

  

value

the content to serialize

  

io_priority

the io priority of the operation

  

cancellable

optional GCancellable object.

[nullable]

callback

callback to call when the operation is done.

[scope async]

user_data

data to pass to the callback function.

[closure]

gdk_content_serialize_finish ()

gboolean
gdk_content_serialize_finish (GAsyncResult *result,
                              GError **error);

Finishes a content serialization operation.

Parameters

result

the GAsyncResult

  

error

return location for an error

  

Returns

TRUE if the operation was successful, FALSE if an error occurred. In this case, error is set

Types and Values
