Syntax

public class BufferResultValidator

Remarks

This is a heuristic test, and may return false positive results (I.e. it may fail to detect an invalid result.) It should never return a false negative result, however (I.e. it should never report a valid result as invalid.)

This test may be (much) more expensive than the original buffer computation.

Constructors

BufferResultValidator(Geometry, double, Geometry)

Declaration

public BufferResultValidator(Geometry input, double distance, Geometry result)

Parameters

Type	Name	Description
Geometry	input
double	distance
Geometry	result

Fields

Verbose

Declaration

public static bool Verbose

Field Value

Type	Description
bool

Properties

ErrorIndicator

Gets a geometry which indicates the location and nature of a validation failure.

If the failure is due to the buffer curve being too far or too close to the input, the indicator is a line segment showing the location and size of the discrepancy.

Declaration

public Geometry ErrorIndicator { get; }

Property Value

Type	Description
Geometry	A geometric error indicator or null, if no error was found

ErrorLocation

Gets the error location

Declaration

public Coordinate ErrorLocation { get; }

Property Value

Type	Description
Coordinate

ErrorMessage

Gets the error message

Declaration

public string ErrorMessage { get; }

Property Value

Type	Description
string

Methods

IsValid()

Declaration

public bool IsValid()

Returns

Type	Description
bool

IsValid(Geometry, double, Geometry)

Declaration

public static bool IsValid(Geometry g, double distance, Geometry result)

Parameters

Type	Name	Description
Geometry	g
double	distance
Geometry	result

Returns

Type	Description
bool

IsValidMessage(Geometry, double, Geometry)

Checks whether the geometry buffer is valid, and returns an error message if not.

Declaration

public static string IsValidMessage(Geometry g, double distance, Geometry result)

Parameters

Type	Name	Description
Geometry	g
double	distance
Geometry	result

Returns

Type	Description
string	An appropriate error message or nullif the buffer is valid
