Method Detail

setIgnoreInvalidLines

public void setIgnoreInvalidLines(boolean ignoreInvalidLines)

Allows invalid lines to be ignored rather than causing Exceptions. An invalid line is one which has only one unique point.

Parameters:

ignoreInvalidLines - true if short lines are to be ignored

setFixInvalidLines

public void setFixInvalidLines(boolean fixInvalidLines)

Allows invalid lines to be ignored rather than causing Exceptions. An invalid line is one which has only one unique point.

Parameters:

fixInvalidLines - true if short lines are to be ignored

add

public void add(Coordinate pt)

Adds a point to the current line.

Parameters:

pt - the Coordinate to add

add

public void add(Coordinate pt,
                boolean allowRepeatedPoints)

Adds a point to the current line.

Parameters:

pt - the Coordinate to add

getLastCoordinate

public Coordinate getLastCoordinate()

endLine

public void endLine()

Terminate the current LineString.

validCoordinateSequence

private Coordinate[] validCoordinateSequence(Coordinate[] pts)

getGeometry

public Geometry getGeometry()
