class Controller from IGESControl inherits Controller from XSControl

    ---Purpose : Controller for IGES-5.1

uses

    CString,
    Protocol from Interface,
    InterfaceModel from Interface,
    WorkLibrary from IFSelect,
    ReturnStatus from IFSelect,
    ActorOfTransientProcess from Transfer,
    FinderProcess from Transfer,
    ActorOfFinderProcess from Transfer,
    WorkSession from XSControl,
    Shape from TopoDS

is

    Create (modefnes : Boolean = Standard_False)
    	returns mutable Controller from IGESControl;
    ---Purpose : Initializes the use of IGES Norm (the first time) and returns
    --           a Controller for IGES-5.1
    --           If <modefnes> is True, sets it to internal FNES format

    NewModel     (me) returns mutable InterfaceModel from Interface;
    ---Purpose : Creates a new empty Model ready to receive data of the Norm.
    --           It is taken from IGES Template Model

    ActorRead    (me; model : InterfaceModel)
                 returns mutable ActorOfTransientProcess from Transfer;
    ---Purpose : Returns the Actor for Read attached to the pair (norm,appli)
    --           It is an Actor from IGESToBRep, adapted from an IGESModel :
    --           Unit, tolerances

    TransferWriteShape (me; shape : Shape from TopoDS;
    	    	    	FP        : mutable FinderProcess  from Transfer;
    	    	        model     : mutable InterfaceModel from Interface;
			modetrans : Integer = 0)
      returns ReturnStatus  is redefined;
    ---Purpose : Takes one Shape and transfers it to the InterfaceModel
    --           (already created by NewModel for instance)
    --           <modetrans> is to be interpreted by each kind of XstepAdaptor
    --           Returns a status : 0 OK  1 No result  2 Fail  -1 bad modeshape
    --               -2 bad model (requires an IGESModel)
    --           modeshape : 0  groupe of face (version < 5.1)
    --                       1  BREP-version 5.1 of IGES

    Init (myclass) returns Boolean;
    ---Purpose : Standard Initialisation. It creates a Controller for IGES and
    --           records it to various names, available to select it later
    --           Returns True when done, False if could not be done
    --           Also, it creates and records an Adaptor for FNES
    Customise (me: mutable; WS : in out WorkSession from XSControl) is redefined;
