class Prism from BRepSweep

---Purpose: Provides natural constructors to build BRepSweep 
--          translated swept Primitives.

uses
    Location from TopLoc,
    NumShape from Sweep,
    Translation from BRepSweep,
    Shape from TopoDS,
    Vec from gp,
    Dir from gp

raises
    ConstructionError from Standard

is
    Create (S    : Shape from TopoDS;
    	    V    : Vec from gp;
    	    Copy : Boolean from Standard = Standard_False;
            Canonize: Boolean from Standard = Standard_True)
    ---Purpose: Builds the prism of base S and vector V. If C is true,
    --          S is copied. If Canonize is true then generated surfaces
    --          are attempted to be canonized in simple types
    returns Prism from BRepSweep;

    Create (S         : Shape from TopoDS;
    	    D         : Dir from gp;
	    Inf       : Boolean from Standard = Standard_True;
    	    Copy      : Boolean from Standard = Standard_False;
            Canonize  : Boolean from Standard = Standard_True)
    ---Purpose: Builds a semi-infinite or an infinite prism of base S.
    --          If Copy is true S is copied.  If Inf is true the prism
    --          is infinite, if Inf is false the  prism is infinite in
    --          the direction D. If Canonize is true then generated surfaces
    --          are attempted to be canonized in simple types
    returns Prism from BRepSweep;

    Shape (me : in out)
    ---Purpose: Returns the TopoDS Shape attached to the prism.
    returns Shape from TopoDS
    is static;

    Shape (me : in out; aGenS : Shape from TopoDS)
    ---Purpose: Returns    the  TopoDS  Shape   generated  with  aGenS
    --          (subShape  of the generating shape).
    returns Shape from TopoDS
    is static;

    FirstShape (me : in out)
    ---Purpose: Returns the  TopoDS  Shape of the bottom of the prism.
    returns Shape from TopoDS
    is static;

    FirstShape (me : in out; aGenS : Shape from TopoDS)
    ---Purpose: Returns the TopoDS Shape of the bottom  of the  prism.
    --          generated  with  aGenS  (subShape  of  the  generating
    --          shape).
    returns Shape from TopoDS
    is static;

    LastShape (me : in out)
    ---Purpose: Returns the TopoDS Shape of the top of the prism.
    returns Shape from TopoDS
    is static;

    LastShape (me : in out; aGenS : Shape from TopoDS)
    ---Purpose: Returns the  TopoDS  Shape of the top  of  the  prism.
    --          generated  with  aGenS  (subShape  of  the  generating
    --          shape).
    returns Shape from TopoDS
    is static;

    Vec(me) 
    ---Purpose: Returns the Vector of the Prism,  if it is an infinite
    --          prism the Vec is unitar.
    returns Vec from gp
    is static;

    NumShape (me)
    returns NumShape from Sweep
    ---Purpose: used to build the NumShape of a limited prism.
    is static private;

    NumShape (me; Inf : Boolean from Standard) 
    returns NumShape from Sweep
    ---Purpose: used to build the NumShape of an infinite prism.
    is static private;

    Location(me; V : Vec from gp) 
    returns Location from TopLoc
    ---Purpose: used to build the Location.
    is static private;
