PackedFloatCoordinateSequence(float[], int, int)

Initializes a new instance of the PackedFloatCoordinateSequence class.

Declaration

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

Parameters

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

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)

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).

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

Overrides

CoordinateSequence.GetOrdinate(int, int)

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 float[] GetRawCoordinates()

Returns

Type	Description
float[]	The array of coordinate values

| Edit this page View Source

Reversed()

Returns a reversed copy of this CoordinateSequence.

Declaration

public override CoordinateSequence Reversed()

Returns

Type	Description
CoordinateSequence	A reversed copy of this CoordinateSequence.

Overrides

CoordinateSequence.Reversed()

Exceptions

Type	Condition
InvalidOperationException	Thrown when Copy() returned null.

SetOrdinate(int, int, 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
int	index	The coordinate index.
int	ordinateIndex	The ordinate index in the coordinate, 0 based, smaller than the number of dimensions.
double	value	The new ordinate value.

Overrides

CoordinateSequence.SetOrdinate(int, int, double)

Remarks

Warning: for performance reasons the ordinate index is not checked: if it is over dimensions you may not get an exception but a meaningless value.
