This interface is implemented by NAObject objects, in order to be able to keep the trace of all duplicated objects.

na_iduplicable_dispose ()

void                na_iduplicable_dispose              (const NAIDuplicable *object);

Releases resources.

Since 2.30

na_iduplicable_dump ()

void                na_iduplicable_dump                 (const NAIDuplicable *object);

Dumps via g_debug the properties of the object.

We ouput here only the data we set ourselves againt the NAIDuplicable -implemented object.

This function should be called by the implementation when it dumps itself its own content.

Since 2.30

na_iduplicable_duplicate ()

NAIDuplicable *     na_iduplicable_duplicate            (const NAIDuplicable *object);

Exactly duplicates a NAIDuplicable -implemented object, including modification and validity status which are copied from object to the duplicated one.

Though this function is not recursive by itself, it is widely supposed everywhere in the program that recursivity is provided but NAObject implementation.

Since 2.30

na_iduplicable_check_status ()

void                na_iduplicable_check_status         (const NAIDuplicable *object);

Checks the edition status of the NAIDuplicable object, and set up the corresponding properties.

This function is supposed to be called each time the object may have been modified in order to set the corresponding properties. Helper functions na_iduplicable_is_modified() and na_iduplicable_is_valid() will then only return the current value of the properties.

na_iduplicable_check_status() is not, as itself, recursive. That is, the modification and validity status are only set on the specified object. NAObject implementation has chosen to handle itself the recursivity: na_object_check_status() so first check status for children, before calling this function.

Since 2.30

na_iduplicable_get_origin ()

NAIDuplicable *     na_iduplicable_get_origin           (const NAIDuplicable *object);

Returns the origin of a duplicated NAIDuplicable.

Since 2.30

na_iduplicable_is_valid ()

gboolean            na_iduplicable_is_valid             (const NAIDuplicable *object);

Returns the current value of the relevant property without rechecking the edition status itself.

Since 2.30

na_iduplicable_is_modified ()

gboolean            na_iduplicable_is_modified          (const NAIDuplicable *object);

Returns the current value of the 'is_modified' property without rechecking the edition status itself.

Since 2.30

na_iduplicable_set_origin ()

void                na_iduplicable_set_origin           (NAIDuplicable *object,
                                                         const NAIDuplicable *origin);

Sets the new origin of a duplicated NAIDuplicable.

Since 2.30

na_iduplicable_set_modified ()

void                na_iduplicable_set_modified         (NAIDuplicable *object,
                                                         gboolean modified);

Sets the new modified of a duplicated NAIDuplicable.

Since 2.30

na_iduplicable_register_consumer ()

void                na_iduplicable_register_consumer    (GObject *consumer);

This function registers a consumer, i.e. an instance to which edition status signals will be propagated.

Since 2.30
