Method Details

findPtNotNode

public static Coordinate findPtNotNode(Coordinate[] testCoords,
                                       LinearRing searchRing,
                                       GeometryGraph graph)
Find a point from the list of testCoords that is NOT a node in the edge for the list of searchCoords
Returns:
the point found, or null if none found

getValidationError

public TopologyValidationError getValidationError()

isValid

public boolean isValid()

isValid

public static boolean isValid(Coordinate coord)
Checks whether a coordinate is valid for processing. Coordinates are valid iff their x and y ordinates are in the range of the floating point representation.
Parameters:
coord - the coordinate to validate
Returns:
true if the coordinate is valid
