Redundant keyword 'mutable' removed in CDL files. In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed. Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.

deferred generic class Recognizer from Interface
|
|
(TheKey as any;
|
|
TheResul as Transient)
|
|
inherits Transient
|
|
|
|
---Purpose : Defines a correspondance between an object to be recognized,
|
|
-- of type (Kind) TheKey, and a result of the recognition. There
|
|
-- can be no correspondance. When an object is recognized, the
|
|
-- returned result is empty : a Recognizer is not aimed to make
|
|
-- a transfer but to initiate it by giving a correspondant
|
|
--
|
|
-- A Recognizer can be compound, that is, in addition to its own
|
|
-- Eval method if this one has failed, it can ask another
|
|
-- Recognizer to work, and so on : See method Add
|
|
|
|
raises NoSuchObject
|
|
|
|
|
|
is
|
|
|
|
Initialize;
|
|
---Purpose : Assumes that no result has yet been recognized
|
|
|
|
Evaluate (me : mutable; akey : TheKey; res : out TheResul)
|
|
returns Boolean;
|
|
---Purpose : Evaluates if recognition has a result, returns it if yes
|
|
-- In case of success, Returns True and puts result in "res"
|
|
-- In case of Failure, simply Returns False
|
|
-- Works by calling deferred method Eval, and in case of failure,
|
|
-- looks for Added Recognizers to work
|
|
|
|
Result (me) returns TheResul raises NoSuchObject;
|
|
---Purpose : Returns result of last recognition (call of Evaluate)
|
|
|
|
Add (me : mutable; reco : Recognizer);
|
|
---Purpose : Adds a new Recognizer to the Compound, at the end
|
|
-- Several calls to Add work by adding in the order of calls :
|
|
-- Hence, when Eval has failed to recognize, Evaluate will call
|
|
-- Evaluate from the first added Recognizer if there is one,
|
|
-- and to the second if there is still no result, and so on
|
|
|
|
SetOK (me : mutable; aresult : TheResul) is protected;
|
|
---Purpose : Records the result of the recognition. Called by specific
|
|
-- method Eval to record a result : after calling it, Eval has
|
|
-- finished and can return
|
|
|
|
SetKO (me : mutable) is protected;
|
|
---Purpose : Records that recognition gives no result
|
|
|
|
Eval (me : mutable; akey : TheKey) is deferred protected;
|
|
---Purpose : THIS METHOD DEFINES THE RECOGNITION PROTOCOL, it is proper to
|
|
-- each precise type of Recognizer
|
|
-- For a suitable type of akey, it calls SetOK(result) where
|
|
-- result is an empty result of appropriate type, then returns
|
|
|
|
fields
|
|
|
|
theres : TheResul; -- storing result of last evaluation
|
|
|
|
hasnext : Boolean;
|
|
thenext : Recognizer; -- managing compound definition
|
|
|
|
end Recognizer;
