Method Detail

getCoordinateInternal

public Coordinate getCoordinateInternal(int i)

Description copied from class: PackedCoordinateSequence

Returns a Coordinate representation of the specified coordinate, by always building a new Coordinate object

Specified by:

getCoordinateInternal in class PackedCoordinateSequence

Returns:

See Also:

CoordinateSequence.getCoordinate(int)

getRawCoordinates

public float[] getRawCoordinates()

Gets the underlying array containing the coordinate values.

Returns:

the array of coordinate values

size

public int size()

Description copied from interface: CoordinateSequence

Returns the number of coordinates in this sequence.

Returns:

the size of the sequence

See Also:

CoordinateSequence.size()

clone

public java.lang.Object clone()

Description copied from interface: CoordinateSequence

Returns a deep copy of this collection. Called by Geometry#clone.

Specified by:

clone in interface CoordinateSequence

Specified by:

clone in class PackedCoordinateSequence

Returns:

a copy of the coordinate sequence containing copies of all points

See Also:

Object.clone()

getOrdinate

public double getOrdinate(int index,
                          int ordinate)

Description copied from interface: CoordinateSequence

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

Specified by:

getOrdinate in interface CoordinateSequence

Specified by:

getOrdinate in class PackedCoordinateSequence

Parameters:

index - the coordinate index in the sequence

ordinate - the ordinate index in the coordinate (in range [0, dimension-1])

See Also:

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

setOrdinate

public void setOrdinate(int index,
                        int ordinate,
                        double value)

Description copied from class: PackedCoordinateSequence

Sets the ordinate of a coordinate in this sequence.
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.

Specified by:

setOrdinate in interface CoordinateSequence

Specified by:

setOrdinate in class PackedCoordinateSequence

Parameters:

index - the coordinate index

ordinate - the ordinate index in the coordinate, 0 based, smaller than the number of dimensions

value - the new ordinate value

See Also:

org.meteoinfo.jts.geom.PackedCoordinateSequence#setOrdinate(int, int, double)

expandEnvelope

public Envelope expandEnvelope(Envelope env)

Description copied from interface: CoordinateSequence

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

Parameters:

env - the envelope to expand

Returns:

a ref to the expanded envelope
