class ShrunkRange from IntTools
---Purpose:
--- The class provides the computation of
--- a working (shrunk) range [t1, t2] for
--- the 3D-curve of the edge.
uses
Edge from TopoDS,
Vertex from TopoDS,
Range from IntTools,
Box from Bnd,
Context from IntTools,
PContext from IntTools
--raises
is
Create
returns ShrunkRange from IntTools;
---Purpose:
--- Empty constructor
---
Create (aE : Edge from TopoDS;
aV1 : Vertex from TopoDS;
aV2 : Vertex from TopoDS;
aR : Range from IntTools;
ICtx: Context from IntTools)
returns ShrunkRange from IntTools;
---Purpose:
---
SetShrunkRange(me:out; aR:Range from IntTools);
---Purpose:
--- Sets an shrunk range
---
ShrunkRange(me)
returns Range from IntTools;
---C++: return const&
---Purpose:
--- Returns shrunk range
---
BndBox (me)
returns Box from Bnd;
---C++: return const&
---Purpose:
--- Returns bounding box for edge restricted
--- by shrunk range
---
Edge (me)
returns Edge from TopoDS;
---C++: return const&
---Purpose:
--- Returns edge for which
--- the shrunk range is computed
---
Perform(me:out);
---Purpose:
--- Computes shrunk range for
--- an edge given in constructor
---
IsDone (me)
returns Boolean from Standard;
---Purpose:
--- Returns true if no error occured
--- during shrunk range computation
---
ErrorStatus(me)
returns Integer from Standard;
---Purpose:
--- Returns code of computing shrunk range
--- completion
--- 0 - means successful completion
--- 1 - nothing has been done
--- 2 - initial range is out of edge's range
--- 3 - first boundary of initial range is more than
--- last boundary
--- 4 - projection of first vertex failed
--- 5 - projection of second vertex failed
--- 6 - shrunk range can not be computed
--- shrunk range is setted to initial range
---
