Constructor Details

BoundaryHandler

public BoundaryHandler(BiPredicate<EarthLocation,EarthLocation> cutTest,
 List<List<EarthLocation>> lineList)

Creates a new handler.

Parameters:

cutTest - the test function for cuts conforming to isBoundaryCut(noaa.coastwatch.util.EarthLocation, noaa.coastwatch.util.EarthLocation).

lineList - the list of location lines to use for boundary splitting.

Method Details

isBoundaryCut

public boolean isBoundaryCut(EarthLocation a,
 EarthLocation b)

Determines if a line joining two earth locations crosses a boundary cut line in this handler, according to the cut test.

Parameters:

a - the first earth location.

b - the second earth location.

Returns:

true if the line joining the two locations is cut by a boundary, or false if not.

getSplitter

public org.locationtech.jts.geom.Geometry getSplitter()

Gets the boundary splitting geometry for this handler to perform splits on earth location lines and polygons.

Returns:

the geometry to use for splitting.
