Syntax

[Serializable]
public class PackedCoordinateSequenceFactory : CoordinateSequenceFactory

Constructors

PackedCoordinateSequenceFactory()

Initializes a new instance of the PackedCoordinateSequenceFactory class, using double values.

Declaration

public PackedCoordinateSequenceFactory()

PackedCoordinateSequenceFactory(PackedType)

Initializes a new instance of the PackedCoordinateSequenceFactory class.

Declaration

public PackedCoordinateSequenceFactory(PackedCoordinateSequenceFactory.PackedType type)

Parameters

Type	Name	Description
PackedCoordinateSequenceFactory.PackedType	type	The type.

Fields

DoubleFactory

A factory creating Double coordinate sequences

Declaration

public static readonly PackedCoordinateSequenceFactory DoubleFactory

Field Value

Type	Description
PackedCoordinateSequenceFactory

FloatFactory

A factory creating Float coordinate sequences

Declaration

public static readonly PackedCoordinateSequenceFactory FloatFactory

Field Value

Type	Description
PackedCoordinateSequenceFactory

Properties

Type

Gets the type of packed coordinate sequence this factory builds, either Float or Double

Declaration

public PackedCoordinateSequenceFactory.PackedType Type { get; set; }

Property Value

Type	Description
PackedCoordinateSequenceFactory.PackedType	The type of packed array built.

Methods

Create(CoordinateSequence)

Returns a CoordinateSequence based on the given coordinate sequence; whether or not the array is copied is implementation-dependent.

Declaration

public override CoordinateSequence Create(CoordinateSequence coordSeq)

Parameters

Type	Name	Description
CoordinateSequence	coordSeq

Returns

Type	Description
CoordinateSequence

Overrides

CoordinateSequenceFactory.Create(CoordinateSequence)

Create(Coordinate[])

Returns a CoordinateSequence based on the given array; whether or not the array is copied is implementation-dependent.

Declaration

public override CoordinateSequence Create(Coordinate[] coordinates)

Parameters

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

Returns

Type	Description
CoordinateSequence

Overrides

CoordinateSequenceFactory.Create(Coordinate[])

Create(double[], int)

Creates a packed coordinate sequence of type Type from the provided double array using the provided dimension and a measure of 0.

Declaration

[Obsolete("Use an overload that accepts measures.  This overload will be removed in a future release.")]
public CoordinateSequence Create(double[] packedCoordinates, int dimension)

Parameters

Type	Name	Description
double[]	packedCoordinates	The array containing coordinate values
int	dimension	The coordinate dimension

Returns

Type	Description
CoordinateSequence	A packed coordinate sequence of Type

Create(double[], int, int)

Creates a packed coordinate sequence of type Type from the provided double array using the provided dimension and a measure of 0.

Declaration

public CoordinateSequence Create(double[] packedCoordinates, int dimension, int measures)

Parameters

Type	Name	Description
double[]	packedCoordinates	The array containing coordinate values
int	dimension	The coordinate dimension
int	measures	The coordinate measure count

Returns

Type	Description
CoordinateSequence	A packed coordinate sequence of Type

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.

Create(float[], int)

Creates a packed coordinate sequence of type Type from the provided float array using the provided dimension and a measure of 0.

Declaration

[Obsolete("Use an overload that accepts measures.  This overload will be removed in a future release.")]
public CoordinateSequence Create(float[] packedCoordinates, int dimension)

Parameters

Type	Name	Description
float[]	packedCoordinates	The array containing coordinate values
int	dimension	The coordinate dimension

Returns

Type	Description
CoordinateSequence	A packed coordinate sequence of Type

Create(float[], int, int)

Creates a packed coordinate sequence of type Type from the provided float array using the provided dimension and a measure of 0.

Declaration

public CoordinateSequence Create(float[] packedCoordinates, int dimension, int measures)

Parameters

Type	Name	Description
float[]	packedCoordinates	The array containing coordinate values
int	dimension	The coordinate dimension
int	measures	The coordinate measure count

Returns

Type	Description
CoordinateSequence	A packed coordinate sequence of Type
