    Dump(S : Surface from Geom; OS : in out OStream);
	  ---Purpose: Dumps the surface on the stream.

    Write(S : Surface from Geom; OS : in out OStream);
	  ---Purpose: Writes the surface on the stream.

    Read(S : in out Surface from Geom; IS : in out IStream); 
	  ---Purpose: Reads the surface from the stream.


    Dump(C : Curve from Geom; OS : in out OStream);
	  ---Purpose: Dumps the Curve on the stream.

    Write(C : Curve from Geom; OS : in out OStream);
	  ---Purpose: Writes the Curve on the stream.

    Read(C : in out Curve from Geom; IS : in out IStream); 
	  ---Purpose: Reads the Curve from the stream.


    Dump(C : Curve from Geom2d; OS : in out OStream);
	  ---Purpose: Dumps the Curve on the stream.

    Write(C : Curve from Geom2d; OS : in out OStream);
	  ---Purpose: Writes the Curve on the stream.

    Read(C : in out Curve from Geom2d; IS : in out IStream); 
	  ---Purpose: Reads the Curve from the stream.

    GetUndefinedTypeHandler returns UndefinedTypeHandler from GeomTools;

    GetReal(IS : out IStream from Standard; theValue : out Real from Standard);
      ---Purpose: Reads the Standard_Real value from the stream. Zero is read 
      ---         in case of error
