deferred class Selection from IFSelect inherits TShared
|
|
|
|
---Purpose : A Selection allows to define a set of Interface Entities.
|
|
-- Entities to be put on an output file should be identified in
|
|
-- a way as independant from such or such execution as possible.
|
|
-- This permits to handle comprehensive criteria, and to replay
|
|
-- them when a new variant of an input file has to be processed.
|
|
--
|
|
-- Its input can be, either an Interface Model (the very source),
|
|
-- or another-other Selection(s) or any other ouput. All list
|
|
-- computations start from an input Graph (from IFGraph)
|

is

RootResult (me; G : Graph) returns EntityIterator
|
|
raises InterfaceError is deferred;
|
|
---Purpose : Returns the list of selected entities, computed from Input
|
|
-- given as a Graph. Specific to each class of Selection
|
|
-- Note that uniqueness of each entity is not required here
|
|
-- This method can raise an exception as necessary
|
|
|
|
HasUniqueResult (me) returns Boolean is virtual protected;
|
|
---Purpose : Returns True if RootResult guarantees uniqueness for each
|
|
-- Entity. Called by UniqueResult.
|
|
-- Default answer is False. Can be redefined.
|
|
|
|
UniqueResult (me; G : Graph) returns EntityIterator;
|
|
---Purpose : Returns the list of selected entities, each of them beeing
|
|
-- unique. Default definition works from RootResult. According
|
|
-- HasUniqueResult, UniqueResult returns directly RootResult,
|
|
-- or build a Unique Result from it with a Graph.
|
|
|
|
CompleteResult (me; G : Graph) returns EntityIterator is virtual;
|
|
---Purpose : Returns the list of entities involved by a Selection, i.e.
|
|
-- UniqueResult plus the shared entities (directly or not)
|
|
|
|
|
|
FillIterator (me; iter : in out SelectionIterator) is deferred;
|
|
---Purpose : Puts in an Iterator the Selections from which "me" depends
|
|
-- (there can be zero, or one, or a list).
|
|
-- Specific to each class of Selection
|
|
|
|
Label (me) returns AsciiString from TCollection is deferred;
|
|
---Purpose : Returns a text which defines the criterium applied by a
|
|
-- Selection (can be used to be printed, displayed ...)
|
|
-- Specific to each class
