Constructor Detail

LineIterator

public LineIterator()

LineIterator

public LineIterator(org.locationtech.jts.geom.LineString ls,
                    AffineTransform at)

Creates a new instance of LineIterator

Parameters:

ls - The line string the iterator will use

at - The affine transform applied to coordinates during iteration

Method Detail

init

public void init(org.locationtech.jts.geom.LineString ls,
                 AffineTransform at)

Parameters:

ls - linestring

at - transform

getWindingRule

public int getWindingRule()

Returns the winding rule for determining the interior of the path.

Returns:

the winding rule.

isDone

public boolean isDone()

Tests if the iteration is complete.

Returns:

true if all the segments have been read; false otherwise.

next

public void next()

Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that direction.

currentSegment

public int currentSegment(double[] coords)
