II.2.2 Identifying a ClaDb

Two methods allow the manipulation of the identifier of ClaDb objects (“Id” attribute):

• “Id” attribute setter has one argument and sets the identifier. The argument is an identifier (an integer, a String or an Array[int,String]).
• “Id” attribute getter has no argument and returns the identifier of the object (same types as above), or nil if no identifier has been attributed to the object.
