Syntax

[Serializable]
public class DotSpatialAffineCoordinateSequenceFactory : CoordinateSequenceFactory

Constructors

DotSpatialAffineCoordinateSequenceFactory(Ordinates)

Declaration

public DotSpatialAffineCoordinateSequenceFactory(Ordinates ordinates)

Parameters

Type	Name	Description
Ordinates	ordinates

Properties

Instance

Returns the singleton instance of DotSpatialAffineCoordinateSequenceFactory.

Declaration

public static DotSpatialAffineCoordinateSequenceFactory Instance { get; }

Property Value

Type	Description
DotSpatialAffineCoordinateSequenceFactory

Methods

Create(CoordinateSequence)

Creates a CoordinateSequence which is a copy of the given CoordinateSequence. This method must handle null arguments by creating an empty sequence.

Declaration

public override CoordinateSequence Create(CoordinateSequence coordSeq)

Parameters

Type	Name	Description
CoordinateSequence	coordSeq

Returns

Type	Description
CoordinateSequence	A coordinate sequence

Overrides

CoordinateSequenceFactory.Create(CoordinateSequence)

Create(Coordinate[])

Returns a CoordinateArraySequence based on the given array (the array is not copied).

Declaration

public override CoordinateSequence Create(Coordinate[] coordinates)

Parameters

Type	Name	Description
Coordinate[]	coordinates	the coordinates, which may not be null nor contain null elements.

Returns

Type	Description
CoordinateSequence

Overrides

CoordinateSequenceFactory.Create(Coordinate[])

Create(double[])

Creates an instance of this class using the provided xy array for x- and y ordinates

Declaration

public CoordinateSequence Create(double[] xy)

Parameters

Type	Name	Description
double[]	xy	The x- and y-ordinates

Returns

Type	Description
CoordinateSequence	A coordinate sequence

Create(double[], double[], bool)

Creates an instance of this class using the provided xy array for x- and y ordinates, the zm array for either z-ordinates or measure values. This is indicated by isMeasure.

Declaration

public CoordinateSequence Create(double[] xy, double[] zm, bool isMeasure = false)

Parameters

Type	Name	Description
double[]	xy	The x- and y-ordinates
double[]	zm	An array of z- or measure values
bool	isMeasure	A value indicating if zm contains z-ordinates or measure values.

Returns

Type	Description
CoordinateSequence	A coordinate sequence

Create(double[], double[], double[])

Creates an instance of this class using the provided xy array for x- and y ordinates, the z array for z ordinates and m for measure values.

Declaration

public CoordinateSequence Create(double[] xy, double[] z, double[] m)

Parameters

Type	Name	Description
double[]	xy	The x- and y-ordinates
double[]	z	An array of z- or measure values
double[]	m	An array of measure values.

Returns

Type	Description
CoordinateSequence	A coordinate sequence

Create(int, Ordinates)

Creates a CoordinateSequence of the specified size and ordinates. For this to be useful, the CoordinateSequence implementation must be mutable.

Declaration

public override CoordinateSequence Create(int size, Ordinates ordinates)

Parameters

Type	Name	Description
int	size	The number of coordinates.
Ordinates	ordinates	The ordinates each coordinate has. XY is fix, Z and M can be set.

Returns

Type	Description
CoordinateSequence	A coordinate sequence.

Overrides

CoordinateSequenceFactory.Create(int, Ordinates)

Create(int, int, int)

Creates a CoordinateSequence of the specified size and dimension with measure support. For this to be useful, the CoordinateSequence implementation must be mutable.

Declaration

public override CoordinateSequence Create(int size, int dimension, int measures)

Parameters

Type	Name	Description
int	size	The number of coordinates in the sequence
int	dimension	The dimension of the coordinates in the sequence (if user-specifiable, otherwise ignored)
int	measures	The number of measures of the coordinates in the sequence (if user-specifiable, otherwise ignored)

Returns

Type	Description
CoordinateSequence

Overrides

CoordinateSequenceFactory.Create(int, int, int)

Remarks

If the requested dimension or measures are larger than the CoordinateSequence implementation can provide, then a sequence of maximum possible dimension should be created. An error should not be thrown.
