Class CoverageGapFinder

Finds gaps in a polygonal coverage. Gaps are holes in the coverage which are narrower than a given width.

The coverage should be valid according to {@link CoverageValidator}. If this is not the case, some gaps may not be reported, or the invocation may fail.

This is a more accurate way of identifying gaps than using {@link CoverageValidator#setGapWidth(double)}. Gaps which separate the coverage into two disjoint regions are not detected. Gores are not identified as gaps.>

Syntax

public class CoverageGapFinder

Constructors

CoverageGapFinder(Geometry[])

Creates a new polygonal coverage gap finder

Declaration

public CoverageGapFinder(Geometry[] coverage)

Parameters

Type	Name	Description
Geometry[]	coverage	A set of polygons forming a polygonal coverage

Methods

FindGaps(Geometry[], double)

Finds gaps in a polygonal coverage. Returns lines indicating the locations of the gaps.

Declaration

public static Geometry FindGaps(Geometry[] coverage, double gapWidth)

Parameters

Type	Name	Description
Geometry[]	coverage	A set of polygons forming a polygonal coverage
double	gapWidth	The maximum width of gap to detect

Returns

Type	Description
Geometry	A geometry indicating the locations of gaps (which is empty if no gaps were found), or null if the coverage was empty

FindGaps(double)

Finds gaps in the coverage. Returns lines indicating the locations of the gaps.

Declaration

public Geometry FindGaps(double gapWidth)

Parameters

Type	Name	Description
double	gapWidth	The maximum width of gap to detect

Returns

Type	Description
Geometry	A geometry indicating the locations of gaps (which is empty if no gaps were found), or null if the coverage was empty
