class RoughShapeIntersector from BOPTools
---Purpose: The class RoughShapeIntersector describes the algorithm of
-- intersection of bounding boxes of
-- shapes stored in ShapesDataStructure.
-- It stores statuses of intersection in 2 dimension array.
uses
Array1OfListOfInteger from TColStd,
ListOfInteger from TColStd,
HArray2OfIntersectionStatus from BOPTools,
IntersectionStatus from BOPTools,
HArray1OfBox from Bnd,
PShapesDataStructure from BooleanOperations
is
Create(PDS: PShapesDataStructure from BooleanOperations)
returns RoughShapeIntersector from BOPTools;
---Purpose:
-- Initializes algorithm by shapes data structure
--
Perform(me: in out);
---Purpose:
-- Perform computations.
--
-- Warning:
-- Using this function, after the destructor of
-- the object pointed by PDS (see constructor)
-- was invoked, lead to crash.
--
TableOfStatus(me)
returns HArray2OfIntersectionStatus from BOPTools;
---C++: return const &
---Purpose:
-- Returns 2 dimension array of status flags.
-- First indices of the array corresponds to indices of
-- subshapes of Object of myPDS.
-- Second indices of array corresponds to indices of
-- subshapes of Tool of myPDS.
--
IsDone(me) returns Boolean from Standard;
---Purpose:
-- Returns False if some errors occured during
-- computations or method Perform
-- was not invoked before,
-- otherwise returns True.
--
