Constructor Detail

PointsSubsequence

public PointsSubsequence(Points points,
                         int startIdx)

Creates a new PointsSubsequence instance from the given list of Points.

Parameters:

points -

startIdx -

Method Detail

get

public Point get(int i)

Description copied from interface: Points

Returns the Point at the specified position.

NOTE: It is generally more expensive to use this method than to access a Point by iterating over this object, because a new Point object may have to be created (depending on the implementation).

Specified by:

get in interface Points

Returns:

the point at the specified position

getAsArray

public double[] getAsArray()

Description copied from interface: Points

Returns all coordinates of the contained Points as an array.

NOTE: This method should be avoided, as it may involve expensive operations.

Specified by:

getAsArray in interface Points

Returns:

coordinates as a one-dimensional array

getDimension

public int getDimension()

Description copied from interface: Points

Returns the coordinate dimension, i.e. the dimension of the space that the points are embedded in.

Specified by:

getDimension in interface com.vividsolutions.jts.geom.CoordinateSequence

Specified by:

getDimension in interface Points

Returns:

the coordinate dimension

size

public int size()

Description copied from interface: Points

Returns the number of represented Points.

Specified by:

size in interface com.vividsolutions.jts.geom.CoordinateSequence

Specified by:

size in interface Points

Returns:

the number of points

iterator

public Iterator<Point> iterator()

Specified by:

iterator in interface Iterable<Point>

getEndPoint

public Point getEndPoint()

Description copied from interface: Points

Returns the last point of the sequence.

Specified by:

getEndPoint in interface Points

Returns:

the last point

getStartPoint

public Point getStartPoint()

Description copied from interface: Points

Returns the first point of the sequence.

Specified by:

getStartPoint in interface Points

Returns:

the first point

expandEnvelope

public com.vividsolutions.jts.geom.Envelope expandEnvelope(com.vividsolutions.jts.geom.Envelope env)

Specified by:

expandEnvelope in interface com.vividsolutions.jts.geom.CoordinateSequence

getCoordinate

public com.vividsolutions.jts.geom.Coordinate getCoordinate(int index)

Specified by:

getCoordinate in interface com.vividsolutions.jts.geom.CoordinateSequence

getCoordinate

public void getCoordinate(int index,
