Member Function Documentation

void geos::linearref::LinearGeometryBuilder::add

(

const geom::Coordinate &

pt

)

Adds a point to the current line.

Parameters

pt	the Coordinate to add

void geos::linearref::LinearGeometryBuilder::add	(	const geom::Coordinate &	pt,
		bool	allowRepeatedPoints
	)

Adds a point to the current line.

Parameters

pt	the Coordinate to add
allowRepeatedPoints	if set to false, repeated coordinates are collapsed

void geos::linearref::LinearGeometryBuilder::endLine

(

)

Terminate the current LineString.

const

void geos::linearref::LinearGeometryBuilder::setFixInvalidLines

(

bool

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

void geos::linearref::LinearGeometryBuilder::setIgnoreInvalidLines

(

bool

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
