deferred class SelectCombine from IFSelect inherits Selection
|
|
|
|
---Purpose : A SelectCombine type Selection defines algebraic operations
|
|
-- between results of several Selections
|
|
-- It is a deferred class : sub-classes will have to define
|
|
-- precise what operator is to be applied
|
|
|

|
|
Initialize;
|
|
---Purpose : Defines an empty SelectCombine
|
|
|
|
NbInputs (me) returns Integer;
|
|
---Purpose : Returns the count of Input Selections
|
|
|
|
Input (me; num : Integer) returns mutable Selection;
|
|
---Purpose : Returns an Input Selection, given its rank in the list
|
|
|
|
InputRank (me; sel : Selection) returns Integer;
|
|
---Purpose : Returns the rank of an input Selection, 0 if not in the list.
|
|
-- Most generally, its value is meaningless, except for testing
|
|
-- the presence of an input Selection :
|
|
-- - == 0 if <sel> is not an input for <me>
|
|
-- - > 0 if <sel> is an input for <me>
|
|
|
|
Add (me : mutable; sel : mutable Selection; atnum : Integer = 0);
|
|
---Purpose : Adds a Selection to the filling list
|
|
-- By default, adds it to the end of the list
|
|
-- A Positive rank less then NbInputs gives an insertion rank
|
|
-- (InsertBefore : the new <atnum>th item of the list is <sel>)
|
|
|
|
Remove (me : mutable; sel : Selection) returns Boolean;
|
|
---Purpose : Removes an input Selection.
|
|
-- Returns True if Done, False, if <sel> is not an input for <me>
|
|
|
|
Remove (me : mutable; num : Integer) returns Boolean;
|
|
---Purpose : Removes an input Selection, given its rank in the list
|
|
-- Returns True if Done, False if <num> is out of range
|
|
|
|
|
|
HasUniqueResult (me) returns Boolean is redefined protected;
|
|
---Purpose : Returns always True, because RootResult gives a Unique list
|
|
|
|
|
|
FillIterator (me; iter : in out SelectionIterator);
|
|
---Purpose : Puts in an Iterator the Selections from which "me" depends
|
|
-- That is to say, the list of Input Selections
