This type defines the prototype of a function that is called to create a node (or a link).

Parameters:

	buff	The definition of the object.
	arg	The user data.

Returns:

The created object or null if there is a problem.

IliDefineObjectCallback

This type defines the prototype of a function that is called to define the data of a node (or a link) before appending into a data source.

Parameters:

	buff	The data buffer which contains the object data.
	g	The current graphic object if already exists.
	arg	The user data.

Returns:

IlTrue if the node (or link) can be created. Otherwise, it returns IlFalse.

IliUpdateObjectCallback

This type defines the prototype of a function that is called to update a node or a link.

Parameters:

	previous	The object that must be updated.
	buff	The new definition of the object.
	arg	The user data.

Returns:

The updated object. If the returned object is a new object, the old object is deleted by the IliDbGrapher object.
