23 class SelectEntityNumber from IFSelect inherits SelectBase
25 ---Purpose : A SelectEntityNumber gets in an InterfaceModel (through a
26 -- Graph), the Entity which has a specified Number (its rank of
27 -- adding into the Model) : there can be zero (if none) or one.
28 -- The Number is not directly defined as an Integer, but as a
29 -- Parameter, which can be externally controled
31 uses AsciiString from TCollection, EntityIterator, Graph, IntParam
35 Create returns mutable SelectEntityNumber;
36 ---Purpose : Creates a SelectEntityNumber, initially with no specified Number
38 SetNumber (me : mutable; num : mutable IntParam);
39 ---Purpose : Sets Entity Number to be taken (initially, none is set : 0)
41 Number (me) returns mutable IntParam;
42 ---Purpose : Returns specified Number (as a Parameter)
44 RootResult (me; G : Graph) returns EntityIterator;
45 ---Purpose : Returns the list of selected entities : the Entity having the
46 -- specified Number (this result assures naturally uniqueness)
48 Label (me) returns AsciiString from TCollection;
49 ---Purpose : Returns a text defining the criterium : "Entity Number ..."
