class IteratorOfCoupleOfShape from BOPTools
---Purpose: The class IteratorOfCoupleOfShape provides the iteration
--- on the couples of shapes stored in ShapesDataStructure
--- according to the given types of shapes and
--- status of their intersection.
--- The statuses are stored in 2 dimension array.
uses
ShapeEnum from TopAbs,
HArray2OfIntersectionStatus from BOPTools,
PShapesDataStructure from BooleanOperations,
IntersectionStatus from BOPTools,
ListOfCoupleOfInteger from BOPTools,
ListIteratorOfListOfCoupleOfInteger from BOPTools,
NoSuchObject from Standard
raises NoSuchObject from Standard
is

returns IteratorOfCoupleOfShape from BOPTools;
---Purpose:
--- Empty Constructor
---
Create(PDS: PShapesDataStructure from BooleanOperations;
Type1: ShapeEnum from TopAbs;
Type2: ShapeEnum from TopAbs)
returns IteratorOfCoupleOfShape from BOPTools;
---Purpose:
--- Initializes iterator by ShapesDataStructure and
--- shape types
---
Destroy(me: in out) is virtual;
---C++: alias "Standard_EXPORT virtual ~BOPTools_IteratorOfCoupleOfShape(){Destroy();}"
Initialize(me: in out; Type1: ShapeEnum from TopAbs;
Type2: ShapeEnum from TopAbs)
raises NoSuchObject from Standard
is virtual;
---Purpose:
--- Initializes iterator with shape types.
--- The iterator uses PDS assigned in constructor or in SetDataStructure().
--- Raises the exception if myPDS is null.
---
SetDataStructure(me: in out; PDS: PShapesDataStructure from BooleanOperations)
raises
NoSuchObject from Standard;
---Purpose:
--- Initialize iterator with ShapeDataStructure.
---
More(me)
returns Boolean from Standard
is virtual;
---Purpose:
--- Returns True if there are still not
--- treated couples of shapes
---
Next(me: in out)
is virtual;
---Purpose:
--- Moves to the next couple of iteration
---
Current(me; Index1: in out Integer from Standard;
Index2: in out Integer from Standard;
WithSubShape: out Boolean from Standard)
is virtual;
---Purpose:
--- Returns current couple of indices and
--- flag WithSubShape which is true
--- if bounding boxes of subshapes
--- are intersected
---
ListOfCouple(me)
returns ListOfCoupleOfInteger from BOPTools;
---C++: return const &
---Purpose:
--- Returns a list of couples of shape indices
--- according to shape types by which
--- the iterator was initialized

---Purpose:
--- Sets status to array according to Index1 and Index2
---
GetTableOfIntersectionStatus(me)
returns HArray2OfIntersectionStatus from BOPTools;
---C++: return const &
---Purpose:
--- Returns 2 dimension array of intersection statuses
---

---Purpose:
--- For internal use
