closeRing()

void geos::operation::buffer::OffsetSegmentString::closeRing ( )

inline

Check that points are a ring

add the startpoint again if they are not

getCoordinates()

geom::CoordinateSequence * geos::operation::buffer::OffsetSegmentString::getCoordinates ( void  )

inline

Get coordinates by taking ownership of them

After this call, the coordinates reference in this object are dropped. Calling twice will segfault...

FIXME: refactor memory management of this
