class Protocol from IGESData inherits Protocol from Interface
---Purpose : Description of basic Protocol for IGES
-- This comprises treatement of IGESModel and Recognition of
-- Undefined-FreeFormat-Entity
uses OStream, Type, InterfaceModel, Check
is
Create returns mutable Protocol from IGESData;
NbResources (me) returns Integer;
---Purpose : Gives the count of Resource Protocol. Here, none
Resource (me; num : Integer) returns Protocol from Interface;
---Purpose : Returns a Resource, given a rank. Here, none
TypeNumber (me; atype : any Type) returns Integer;
---Purpose : Returns a Case Number, specific of each recognized Type
-- Here, Undefined and Free Format Entities have the Number 1.
-- -- General Services (defined at Norm level) -- --
NewModel (me) returns mutable InterfaceModel;
---Purpose : Creates an empty Model for IGES Norm
IsSuitableModel (me; model : InterfaceModel) returns Boolean;
---Purpose : Returns True if <model> is a Model of IGES Norm
UnknownEntity (me) returns mutable Transient;
---Purpose : Creates a new Unknown Entity for IGES (UndefinedEntity)
IsUnknownEntity (me; ent : Transient) returns Boolean;
---Purpose : Returns True if <ent> is an Unknown Entity for the Norm, i.e.
-- Type UndefinedEntity, status Unknown
end Protocol;
