Syntax

[Serializable]
public class PackedDoubleCoordinateSequence : PackedCoordinateSequence

Constructors

PackedDoubleCoordinateSequence(Coordinate[])

Initializes a new instance of the PackedDoubleCoordinateSequence class.

Declaration

public PackedDoubleCoordinateSequence(Coordinate[] coords)

Parameters

Type	Name	Description
Coordinate[]	coords	An array of Coordinates.

PackedDoubleCoordinateSequence(Coordinate[], Int32)

Initializes a new instance of the PackedDoubleCoordinateSequence class.

Declaration

[Obsolete("Use an overload that accepts measures.  This overload will be removed in a future release.")]
public PackedDoubleCoordinateSequence(Coordinate[] coords, int dimension)

Parameters

Type	Name	Description
Coordinate[]	coords	An array of Coordinates.
Int32	dimension	The total number of ordinates that make up a Coordinate in this sequence.

PackedDoubleCoordinateSequence(Coordinate[], Int32, Int32)

Initializes a new instance of the PackedDoubleCoordinateSequence class.

Declaration

public PackedDoubleCoordinateSequence(Coordinate[] coords, int dimension, int measures)

Parameters

Type	Name	Description
Coordinate[]	coords	An array of Coordinates.
Int32	dimension	The total number of ordinates that make up a Coordinate in this sequence.
Int32	measures	The number of measure-ordinates each Coordinate in this sequence has.

PackedDoubleCoordinateSequence(Double[], Int32, Int32)

Initializes a new instance of the PackedDoubleCoordinateSequence class.

Declaration

public PackedDoubleCoordinateSequence(double[] coords, int dimension, int measures)

Parameters

Type	Name	Description
Double[]	coords	An array of double values that contains the ordinate values of the sequence.
Int32	dimension	The total number of ordinates that make up a Coordinate in this sequence.
Int32	measures	The number of measure-ordinates each Coordinate in this sequence has.

PackedDoubleCoordinateSequence(Int32, Int32, Int32)

Initializes a new instance of the PackedDoubleCoordinateSequence class.

Declaration

public PackedDoubleCoordinateSequence(int size, int dimension, int measures)

Parameters

Type	Name	Description
Int32	size	The number of coordinates in this sequence
Int32	dimension	The total number of ordinates that make up a Coordinate in this sequence.
Int32	measures	The number of measure-ordinates each Coordinate in this sequence has.

PackedDoubleCoordinateSequence(Single[], Int32, Int32)

Initializes a new instance of the PackedDoubleCoordinateSequence class.

Declaration

public PackedDoubleCoordinateSequence(float[] coords, int dimension, int measures)

Parameters

Type	Name	Description
Single[]	coords	An array of float values that contains the ordinate values of the sequence.
Int32	dimension	The total number of ordinates that make up a Coordinate in this sequence.
Int32	measures	The number of measure-ordinates each Coordinate in this sequence has.

Methods

Copy()

Declaration

public override CoordinateSequence Copy()

Returns

Type	Description
CoordinateSequence

Overrides

CoordinateSequence.Copy()

ExpandEnvelope(Envelope)

Expands the given Envelope to include the coordinates in the sequence. Allows implementing classes to optimize access to coordinate values.

Declaration

public override Envelope ExpandEnvelope(Envelope env)

Parameters

Type	Name	Description
Envelope	env	The envelope to expand.

Returns

Type	Description
Envelope	A reference to the expanded envelope.

Overrides

CoordinateSequence.ExpandEnvelope(Envelope)

GetOrdinate(Int32, Int32)

Returns the ordinate of a coordinate in this sequence. Ordinate indices 0 and 1 are assumed to be X and Y. Ordinate indices greater than 1 have user-defined semantics (for instance, they may contain other dimensions or measure values).

Declaration

public override double GetOrdinate(int index, int ordinateIndex)

Parameters

Type	Name	Description
Int32	index	The coordinate index in the sequence.
Int32	ordinateIndex	The ordinate index in the coordinate (in range [0, dimension-1]).

Returns

Type	Description
Double

Overrides

CoordinateSequence.GetOrdinate(Int32, Int32)

Remarks

Beware, for performance reasons the ordinate index is not checked, if it's over dimensions you may not get an exception but a meaningless value.

GetRawCoordinates()

Gets the underlying array containing the coordinate values.

Declaration

public double[] GetRawCoordinates()

Returns

Type	Description
Double[]	The array of coordinate values

Reversed()

Declaration

public override CoordinateSequence Reversed()

Returns

Type	Description
CoordinateSequence

Overrides

CoordinateSequence.Reversed()

SetOrdinate(Int32, Int32, Double)

Sets the ordinate of a coordinate in this sequence.

Declaration

public override void SetOrdinate(int index, int ordinateIndex, double value)

Parameters

Type	Name	Description
Int32	index	The coordinate index.
Int32	ordinateIndex	The ordinate index in the coordinate, 0 based, smaller than the number of dimensions.
Double	value	The new ordinate value.

Overrides

CoordinateSequence.SetOrdinate(Int32, Int32, Double)

Remarks

Warning: for performance reasons the ordinate index is not checked. If it is larger than the dimension a meaningless value may be returned.
