Method Details

clone

public Object clone()
Specified by:
clone in interface CoordinateSequence
Overrides:
clone in interface PackedCoordinateSequence
See Also:
java.lang.Object.clone()

expandEnvelope

public Envelope expandEnvelope(Envelope env)
Expands the given Envelope to include the coordinates in the sequence. Allows implementing classes to optimize access to coordinate values.
Specified by:
expandEnvelope in interface CoordinateSequence
Parameters:
env - the envelope to expand
Returns:
a ref to the expanded envelope

getCoordinateInternal

public Coordinate getCoordinateInternal(int i)
Overrides:
getCoordinateInternal in interface PackedCoordinateSequence
See Also:
CoordinateSequence.getCoordinate(int)

getOrdinate

public double getOrdinate(int index,
                          int ordinate)
Specified by:
getOrdinate in interface CoordinateSequence
Overrides:
getOrdinate in interface PackedCoordinateSequence
See Also:
Beware, for performace reasons the ordinate index is not checked, if it's over dimensions you may not get an exception but a meaningless value.

setOrdinate

public void setOrdinate(int index,
                        int ordinate,
                        double value)
Specified by:
setOrdinate in interface CoordinateSequence
Overrides:
setOrdinate in interface PackedCoordinateSequence
See Also:
com.vividsolutions.jts.geom.PackedCoordinateSequence.setOrdinate(int, int, double)

size

public int size()
Specified by:
size in interface CoordinateSequence
See Also:
CoordinateSequence.size()
