The operator diameter_regiondiameter_regiondiameter_regionDiameterRegionDiameterRegion calculates the
maximal distance between two boundary points of
a region. The coordinates of these two extremes
and the distance between them will be returned.
If the region is empty, the results of Row1Row1Row1Row1row1, Column1Column1Column1Column1column1,
Row2Row2Row2Row2row2 and Column2Column2Column2Column2column2 (all of them = 0) may lead to
confusion.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
Row1Row1Row1Row1row1 (output_control) line.begin.y(-array) → HTupleHTupleVARIANTHtuple (integer) (int / long) (Hlong) (Hlong) (Hlong)
Row index of the first extreme point.
Column index of the first extreme point.
Row2Row2Row2Row2row2 (output_control) line.end.y(-array) → HTupleHTupleVARIANTHtuple (integer) (int / long) (Hlong) (Hlong) (Hlong)
Row index of the second extreme point.
Column index of the second extreme point.
Distance of the two extreme points.
If F is the area of a region, the runtime
complexity amounts to O(sqrt(F)) on average.
The operator diameter_regiondiameter_regiondiameter_regionDiameterRegionDiameterRegion returns the value 2 (H_MSG_TRUE), if the input
is not empty. The reaction to empty input (no input regions are
available) may be determined with the help of the operator
set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). The reaction
concerning an empty region (region is the empty set) will be determined
by the operator set_system('empty_region_result',<Result>)set_system("empty_region_result",<Result>)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>).
If necessary an exception is raised.
