deferred generic class Tool from Sweep (TheShape as any)
---Purpose: This is a signature class describing the indexation
-- and type analysis services required by the Directing
-- and Generating Shapes of Swept Primitives.
--
uses
ShapeEnum from TopAbs,
Orientation from TopAbs
raises
OutOfRange from Standard
is
Initialize(aShape: TheShape);
---Purpose: Initialize the tool with <aShape>. The IndexTool
-- must prepare an indexation for all the subshapes
-- of this shape.
NbShapes(me) returns Integer
---Purpose: Returns the number of subshapes in the shape.
is deferred;
Index(me; aShape : TheShape) returns Integer
---Purpose: Returns the index of <aShape>.
is deferred;
Shape(me; anIndex : Integer from Standard) returns TheShape
---Purpose: Returns the Shape of index anIndex
is deferred;
Type(me; aShape : TheShape) returns ShapeEnum from TopAbs
---Purpose: Returns the type of <aShape>.
is deferred;
Orientation(me; aShape : TheShape) returns Orientation from TopAbs
---Purpose: Returns the Orientation of <aShape>.
is deferred;
SetOrientation(me; aShape : in out TheShape; Or : Orientation from TopAbs)
---Purpose: Set the Orientation of <aShape> with Or.

------------------------------------------
--- Methods used for Directing Shapes only
------------------------------------------
HasFirstVertex(me) returns Boolean from Standard
---Purpose: Returns true if there is a First Vertex in the Shape.
is deferred;
HasLastVertex(me) returns Boolean from Standard
---Purpose: Returns true if there is a Last Vertex in the Shape.
is deferred;
FirstVertex(me) returns TheShape
---Purpose: Returns the first vertex.
is deferred;
LastVertex(me) returns TheShape
---Purpose: Returns the last vertex.
