Syntax

[Serializable]
public abstract class CoordinateSequenceFactory

Constructors

CoordinateSequenceFactory()

Initializes a new instance of the CoordinateSequenceFactory class.`

Declaration

protected CoordinateSequenceFactory()

CoordinateSequenceFactory(Ordinates)

Initializes a new instance of the CoordinateSequenceFactory class.

Declaration

protected CoordinateSequenceFactory(Ordinates ordinates)

Parameters

Type	Name	Description
Ordinates	ordinates	The maximum set of Ordinates flags that this instance will be able to create sequences for.

Properties

Ordinates

Gets the Ordinate flags that sequences created by this factory can maximal cope with.

Declaration

public Ordinates Ordinates { get; }

Property Value

Type	Description
Ordinates

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 virtual CoordinateSequence Create(CoordinateSequence coordSeq)

Parameters

Type	Name	Description
CoordinateSequence	coordSeq

Returns

Type	Description
CoordinateSequence	A coordinate sequence

Create(Coordinate[])

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

Declaration

public virtual CoordinateSequence Create(Coordinate[] coordinates)

Parameters

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

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 virtual 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.

Create(int, int)

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

Declaration

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

Parameters

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

Returns

Type	Description
CoordinateSequence	A coordinate sequence

Remarks

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

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 abstract 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

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.

GetCommonSequenceParameters(Coordinate[])

Gets the three parameters needed to create any CoordinateSequence instance (Count, Dimension, and Measures) such that the sequence can store all the data from a given array of Coordinate instances.

Declaration

public static (int Count, int Dimension, int Measures) GetCommonSequenceParameters(Coordinate[] coordinates)

Parameters

Type	Name	Description
Coordinate[]	coordinates	The array of Coordinate instances that the sequence will be created from.

Returns

Type	Description
(int Count, int Dimension, int Measures)	The values of the three parameters to use for creating the sequence.
