GdaBlobOp has a class definition as:


struct _GdaBlobOpClass {
	GObjectClass parent_class;
	gpointer     functions;

	/*< private >*/
	/* Padding for future expansion */
	void (*_gda_reserved1) (void);
	void (*_gda_reserved2) (void);
	void (*_gda_reserved3) (void);
	void (*_gda_reserved4) (void);
};

This makes use functions as a pointer to GdaBlobOpFunctions, which I think, should be virtual methods directly on GdaBlobOpClass.




and a object definition as:

struct _GdaBlobOp {
	GObject object;
	GdaBlobOpPrivate *priv;

	/* Padding for future expansion */
	gpointer _gda_reserved1;
};


Should we use g_type_add_class_private() and G_TYPE_CLASS_GET_PRIVATE() to install private data?

For gda_reserved1, I think we need not install class members, but private ones, using getters/setters, as a convention.

Pending for comments in order to continue this changes.
