Methods

Copy()

Returns a deep copy of this collection.

Declaration

public override CoordinateSequence Copy()

Returns

Type	Description
CoordinateSequence	A copy of the coordinate sequence containing copies of all points

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)

GetCoordinate(int, Coordinate)

Copies the i'th coordinate in the sequence to the supplied Coordinate. At least the first two dimensions must be copied.

Declaration

public override void GetCoordinate(int index, Coordinate coord)

Parameters

Type	Name	Description
int	index	The index of the coordinate to copy.
Coordinate	coord	A Coordinate to receive the value.

Overrides

CoordinateSequence.GetCoordinate(int, Coordinate)

GetCoordinateCopy(int)

Returns a copy of the i'th coordinate in this sequence. This method optimizes the situation where the caller is going to make a copy anyway - if the implementation has already created a new Coordinate object, no further copy is needed.

Declaration

public override Coordinate GetCoordinateCopy(int i)

Parameters

Type	Name	Description
int	i	The index of the coordinate to retrieve.

Returns

Type	Description
Coordinate	A copy of the i'th coordinate in the sequence

Overrides

CoordinateSequence.GetCoordinateCopy(int)

GetM(int)

Returns ordinate M of the specified coordinate if available.

Declaration

public override double GetM(int index)

Parameters

Type	Name	Description
int	index

Returns

Type	Description
double	The value of the M ordinate in the index'th coordinate, or NullOrdinate if not defined.

Overrides

CoordinateSequence.GetM(int)

GetOrdinate(int, int)

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 as described by Dimension and Measures.

Declaration

public override double GetOrdinate(int index, int ordinateIndex)

Parameters

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

Returns

Type	Description
double	The ordinate value, or NullOrdinate if the sequence does not provide values for ordinateIndex"/>

Overrides

CoordinateSequence.GetOrdinate(int, int)

Remarks

If the sequence does not provide value for the required ordinate, the implementation must not throw an exception, it should return NullOrdinate.

GetX(int)

Returns ordinate X (0) of the specified coordinate.

Declaration

public override double GetX(int index)

Parameters

Type	Name	Description
int	index

Returns

Type	Description
double	The value of the X ordinate in the index'th coordinate.

Overrides

CoordinateSequence.GetX(int)

GetY(int)

Returns ordinate Y (1) of the specified coordinate.

Declaration

public override double GetY(int index)

Parameters

Type	Name	Description
int	index

Returns

Type	Description
double	The value of the Y ordinate in the index'th coordinate.

Overrides

GetZ(int)

Returns ordinate Z of the specified coordinate if available.

Declaration

public override double GetZ(int index)

Parameters

Type	Name	Description
int	index

Returns

Type	Description
double	The value of the Z ordinate in the index'th coordinate, or NullOrdinate if not defined.

Overrides

CoordinateSequence.GetZ(int)

ReleaseCoordinateArray()

Releases the weak reference to the weak referenced coordinate array

Declaration

public void ReleaseCoordinateArray()

Remarks

This is necessary if you modify the values of the XY, Z, M arrays externally.

Reversed()

Creates a reversed version of this coordinate sequence with cloned Coordinates

Declaration

public override CoordinateSequence Reversed()

Returns

Type	Description
CoordinateSequence	A reversed version of this sequence

Overrides

CoordinateSequence.Reversed()

SetM(int, double)

Sets ordinate M of the specified coordinate to the specified value if present.

Declaration

public override void SetM(int index, double value)

Parameters

Type	Name	Description
int	index	The index of the coordinate whose M value to set if present.
double	value	The value to set the coordinate's M value to if present.

Overrides

CoordinateSequence.SetM(int, double)

SetOrdinate(int, int, double)

Sets the value for a given ordinate of a coordinate in this sequence.

Declaration

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

Parameters

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

Overrides

CoordinateSequence.SetOrdinate(int, int, double)

Remarks

If the sequence can't store the ordinate value, the implementation must not throw an exception, it should simply ignore the call.

SetX(int, double)

Sets ordinate X (0) of the specified coordinate to the specified value.

Declaration

public override void SetX(int index, double value)

Parameters

Type	Name	Description
int	index	The index of the coordinate whose X value to set.

SetY(int, double)

Sets ordinate Y (1) of the specified coordinate to the specified value.

Declaration

public override void SetY(int index, double value)

Parameters

Type	Name	Description
int	index	The index of the coordinate whose Y value to set.
double	value	The value to set the coordinate's Y value to.

public override void SetZ(int index, double value)

Parameters

Type	Name	Description
int	index	The index of the coordinate whose Z value to set if present.
double	value	The value to set the coordinate's Z value to if present.

Overrides

CoordinateSequence.SetZ(int, double)

ToCoordinateArray()

Returns (possibly copies of) the Coordinates in this collection. Whether or not the Coordinates returned are the actual underlying Coordinates or merely copies depends on the implementation. Note that if this implementation does not store its data as an array of Coordinates, this method will incur a performance penalty because the array needs to be built from scratch.

Declaration

public override Coordinate[] ToCoordinateArray()

Returns

Type	Description
Coordinate[]

Overrides

CoordinateSequence.ToCoordinateArray()
