17 deferred class Modifier from IFSelect inherits GeneralModifier
19 ---Purpose : This class gives a frame for Actions which can work globally
20 -- on a File once completely defined (i.e. afterwards)
22 -- Remark : if no Selection is set as criterium, the Modifier is
23 -- set to work and should consider all the content of the Model
26 uses CString, InterfaceModel, CopyTool, Protocol from Interface, ContextModif
30 Initialize (maychangegraph : Boolean);
31 ---Purpose : Calls inherited Initialize, transmits to it the information
34 Perform (me; ctx : in out ContextModif;
35 target : InterfaceModel;
36 protocol : Protocol from Interface;
37 TC : in out CopyTool) is deferred;
38 ---Purpose : This deferred method defines the action specific to each class
39 -- of Modifier. It is called by a ModelCopier, once the Model
40 -- generated and filled. ModelCopier has already checked the
41 -- criteria (Dispatch, Model Rank, Selection) before calling it.
43 -- <ctx> detains informations about original data and selection.
44 -- The result of copying, on which modifications are to be done,
46 -- <TC> allows to run additional copies as required
48 -- In case of Error, use methods CCheck from the ContextModif
49 -- to aknowledge an entity Check or a Global Check with messages
