Constructors

CoordinateSequenceFactory()

Initializes a new instance of the CoordinateSequenceFactory class.`

protected CoordinateSequenceFactory()

CoordinateSequence

CoordinateSequenceFactory(Ordinates)

Initializes a new instance of the CoordinateSequenceFactory class.

protected CoordinateSequenceFactory(Ordinates ordinates)

Parameters

ordinates Ordinates

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

See Also

CoordinateSequence

Properties

Ordinates

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

public Ordinates Ordinates { get; }

Property Value

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.

public virtual CoordinateSequence Create(CoordinateSequence coordSeq)

Parameters

coordSeq CoordinateSequence

Returns

CoordinateSequence

A coordinate sequence

See Also

CoordinateSequence

Create(Coordinate[])

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

public virtual CoordinateSequence Create(Coordinate[] coordinates)

Parameters

coordinates Coordinate[]

A coordinates array, which may not be null nor contain null elements

Returns

CoordinateSequence

A coordinate sequence.

See Also

CoordinateSequence

Create(int, Ordinates)

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

public virtual CoordinateSequence Create(int size, Ordinates ordinates)

Parameters

size int

The number of coordinates.

ordinates Ordinates

The ordinates each coordinate has. XY is fix, Z and M can be set.

Returns

CoordinateSequence

A coordinate sequence.

See Also

CoordinateSequence

Create(int, int)

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

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

Parameters

size int

dimension int

the dimension of the coordinates in the sequence (if user-specifiable, otherwise ignored)

Returns

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.

See Also

CoordinateSequence

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.

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

Parameters

size int

The number of coordinates in the sequence

dimension int

The dimension of the coordinates in the sequence (if user-specifiable, otherwise ignored)

measures int

The number of measures of the coordinates in the sequence (if user-specifiable, otherwise ignored)

Returns

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.

CoordinateSequence

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.

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

Parameters

coordinates Coordinate[]

The array of Coordinate instances that the sequence will be created from.

Returns

(int Count, int Dimension, int Measures)

The values of the three parameters to use for creating the sequence.
