deferred class DiscretRoot from BRepMesh

inherits Transient from Standard

    ---Purpose:
    -- This is a common interface for meshing algorithms
    -- instantiated by Mesh Factory and implemented by plugins.

    ---Purpose:
    -- Setup linear deflection.

    ---C++: alias "Standard_EXPORT virtual ~BRepMesh_DiscretRoot();"

    ---Purpose:
    -- Setup angular deflection.

        returns Real from Standard;
    ---Purpose:
    -- Returns angular deflection.

    SetShape (      me : mutable;
              theShape : Shape from TopoDS);
    ---Purpose:
    -- Set the shape to triangulate.

    Perform (me : mutable)
        is deferred;
    ---Purpose:
    -- Compute triangulation for set shape.

    IsDone (me)
        returns Boolean from Standard;
    ---Purpose:
    -- Returns true if triangualtion was performed and has success.
