Member Function Documentation

◆ add() [1/2]

void geos::linearref::LinearGeometryBuilder::add ( const geom::Coordinate pt)

Adds a point to the current line.

Parameters
ptthe Coordinate to add

◆ add() [2/2]

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

Adds a point to the current line.

Parameters
ptthe Coordinate to add
allowRepeatedPointsif set to false, repeated coordinates are collapsed

◆ setFixInvalidLines()

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
fixInvalidLinestrue if short lines are to be ignored

◆ setIgnoreInvalidLines()

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
ignoreInvalidLinestrue if short lines are to be ignored
