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 class Protocol from Interface inherits TShared
|
|
|
|
---Purpose : General description of Interface Protocols. A Protocol defines
|
|
-- a set of Entity types. This class provides also the notion of
|
|
-- Active Protocol, as a working context, defined once then
|
|
-- exploited by various Tools and Libraries.
|
|
--
|
|
-- It also gives control of type definitions. By default, types
|
|
-- are provided by CDL, but specific implementations, or topics
|
|
-- like multi-typing, may involve another way
|
|
|
|
uses InterfaceModel, Check, Graph
|
|
|

|
|
|
Active (myclass) returns Protocol;
|
|
---Purpose : Returns the Active Protocol, if defined (else, returns a
|
|
-- Null Handle, which means "no defined active protocol")
|
|
|
|
SetActive (myclass; aprotocol : Protocol);
|
|
---Purpose : Sets a given Protocol to be the Active one (for the users of
|
|
-- Active, see just above). Applies to every sub-type of Protocol
|
|
|
|
ClearActive (myclass);
|
|
---Purpose : Erases the Active Protocol (hence it becomes undefined)
|

-- -- General Definition (complies with Template) -- --
|
|
|
|
NbResources (me) returns Integer is deferred;
|
|
---Purpose : Returns count of Protocol used as Resources (level one)
|
|
|
|
Resource (me; num : Integer) returns Protocol is deferred;
|
|
---Purpose : Returns a Resource, given its rank (between 1 and NbResources)
|
|
|
|
CaseNumber (me; obj : any Transient) returns Integer is virtual;
|
|
---Purpose : Returns a unique positive CaseNumber for each Recognized
|
|
-- Object. By default, recognition is based on Type(1)
|
|
-- By default, calls the following one which is deferred.
|
|
|
|
IsDynamicType (me; obj : any Transient) returns Boolean is virtual;
|
|
---Purpose : Returns True if type of <obj> is that defined from CDL
|
|
-- This is the default but it may change according implementation
|
|
|
|
NbTypes (me; obj : any Transient) returns Integer is virtual;
|
|
---Purpose : Returns the count of DISTINCT types under which an entity may
|
|
-- be processed. Each one is candidate to be recognized by
|
|
-- TypeNumber, <obj> is then processed according it
|
|
-- By default, returns 1 (the DynamicType)
|
|
|
|
Type (me; obj : any Transient; nt : Integer = 1) returns Type;
|
|
---Purpose : Returns a type under which <obj> can be recognized and
|
|
-- processed, according its rank in its definition list (see
|
|
-- NbTypes).
|
|
-- By default, returns DynamicType
|
|
|
|
TypeNumber (me; atype : any Type) returns Integer is deferred;
|
|
---Purpose : Returns a unique positive CaseNumber for each Recognized Type,
|
|
-- Returns Zero for "<type> not recognized"
|
|
|
|
GlobalCheck (me; G : Graph; ach : in out Check)
|
|
returns Boolean is virtual;
|
|
---Purpose : Evaluates a Global Check for a model (with its Graph)
|
|
-- Returns True when done, False if data in model do not apply
|
|
--
|
|
-- Very specific of each norm, i.e. of each protocol : the
|
|
-- uppest level Protocol assumes it, it can call GlobalCheck of
|
|
-- its ressources only if it is necessary
|
|
--
|
|
-- Default does nothing, can be redefined
|
|
|
|
-- -- General Services (defined at Norm level) -- --

|
|
NewModel (me) returns InterfaceModel is deferred;
|
|
---Purpose : Creates an empty Model of the considered Norm
|
|
|
|
IsSuitableModel (me; model : InterfaceModel) returns Boolean is deferred;
|
|
---Purpose : Returns True if <model> is a Model of the considered Norm
|
|
|
|
|
|
UnknownEntity (me) returns Transient is deferred;
|
|
---Purpose : Creates a new Unknown Entity for the considered Norm
|
|
|
|
IsUnknownEntity (me; ent : Transient) returns Boolean is deferred;
|
|
---Purpose : Returns True if <ent> is an Unknown Entity for the Norm, i.e.
|
|
-- same Type as them created by method UnknownEntity
|
|
-- (for an Entity out of the Norm, answer can be unpredicable)
