deferred class SelectControl from IFSelect inherits Selection
|
|
|
|
---Purpose : A SelectControl kind Selection works with two input Selections
|
|
-- in a dissymmetric way : the Main Input which gives an input
|
|
-- list of Entities, to be processed, and the Second Input which
|
|
-- gives another list, to be used to filter the main input.
|
|
--
|
|
-- e.g. : SelectDiff retains the items of the Main Input which
|
|
-- are not in the Control Input (which acts as Diff Input)
|
|
-- or a specific selection which retains Entities from the Main
|
|
-- Input if and only if they are concerned by an entity from
|
|
-- the Control Input (such as Views in IGES, etc...)
|
|
--
|
|
-- The way RootResult and Label are produced are at charge of
|
|
-- each sub-class
|
|

is
|
|
|
|
MainInput (me) returns mutable Selection;
|
|
---Purpose : Returns the Main Input Selection
|
|
|
|
HasSecondInput (me) returns Boolean;
|
|
---Purpose : Returns True if a Control Input is defined
|
|
-- Thus, Result can be computed differently if there is a
|
|
-- Control Input or if there is none
|
|
|
|
SecondInput (me) returns mutable Selection;
|
|
---Purpose : Returns the Control Input Selection, or a Null Handle
|
|
|
|
SetMainInput (me : mutable; sel : mutable Selection);
|
|
---Purpose : Sets a Selection to be the Main Input
|
|
|
|
SetSecondInput (me : mutable; sel : mutable Selection);
|
|
---Purpose : Sets a Selection to be the Control Input
|
|
|
|
|
|
-- RootResult,Label remain to be defined by each class of Selection
|
|
-- (also HasUniqueResult if it applies)
|
|
|
|
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
