class SelectSuite from IFSelect inherits SelectDeduct from IFSelect
|
|
|
|
---Purpose : A SelectSuite can describe a suite of SelectDeduct as a unique
|
|
-- one : in other words, it can be seen as a "macro selection"
|
|
--
|
|
-- It works by applying each of its items (which is a
|
|
-- SelectDeduct) on the result computed by the previous one
|
|
-- (by using Alternate Input)
|
|
--
|
|
-- But each of these Selections used as items may be used
|
|
-- independently, it will then give its own result
|
|
--
|
|
-- Hence, SelectSuite gives a way of defining a new Selection
|
|
-- from existing ones, without having to do copies or saves
|
|

Create returns SelectSuite;
|
|
---Purpose : Creates an empty SelectSuite
|
|
|
|
AddInput (me : mutable; item : Selection) returns Boolean;
|
|
---Purpose : Adds an input selection. I.E. :
|
|
-- If <item> is a SelectDeduct, adds it as Previous, not as Input
|
|
-- Else, sets it as Input
|
|
-- Returns True when done
|
|
-- Returns False and refuses to work if Input is already defined
|
|
|
|
AddPrevious (me : mutable; item : SelectDeduct);
|
|
---Purpose : Adds a new first item (prepends to the list). The Input is not
|
|
-- touched
|
|
-- If <item> is null, does nothing
|
|
|
|
AddNext (me : mutable; item : SelectDeduct);
|
|
---Purpose : Adds a new last item (prepends to the list)
|
|
-- If <item> is null, does nothing
|
|
|
|
NbItems (me) returns Integer;
|
|
---Purpose : Returns the count of Items
|
|
|
|
Item (me; num : Integer) returns SelectDeduct;
|
|
---Purpose : Returns an item from its rank in the list
|
|
-- (the Input is always apart)
|
|
|
|
SetLabel (me : mutable; lab : CString);
|
|
---Purpose : Sets a value for the Label
|
|
|
|
-- Definitions for Selecting
|
|
|
|
RootResult (me; G : Graph) returns EntityIterator
|
|
raises InterfaceError;
|
|
---Purpose : Returns the list of selected entities
|
|
-- To do this, once InputResult has been taken (if Input or
|
|
-- Alternate has been defined, else the first Item gives it) :
|
|
-- this result is set as alternate input for the first item,
|
|
-- which computes its result : this result is set as alternate
|
|
-- input for the second item, etc...
|
|
|
|
Label (me) returns AsciiString from TCollection;
|
|
---Purpose : Returns the Label
|
|
-- Either it has been defined by SetLabel, or it will give
|
|
-- "Suite of nn Selections"
