Detailed Description

A list of Coordinates, which may be set to prevent repeated coordinates from occuring in the list.

Use this class when fast insertions and removal at arbitrary position is needed. The class keeps ownership of the Coordinates.

Constructor & Destructor Documentation

geos::geom::CoordinateList::CoordinateList ( const std::vector< Coordinate > &  v)
inline

Constructs a new list from an array of Coordinates, allowing repeated points.

(I.e. this constructor produces a CoordinateList with exactly the same set of points as the input array.)

Parameters
vthe initial coordinates

Member Function Documentation

iterator geos::geom::CoordinateList::insert ( iterator  pos,
const Coordinate c,
bool  allowRepeated 
)
inline

Inserts the specified coordinate at the specified position in this list.

Parameters
posthe position at which to insert
coordthe coordinate to insert
allowRepeatedif set to false, repeated coordinates are collapsed
Returns
an iterator to the newly installed coordinate (or previous, if equal and repeated are not allowed)

NOTE: when allowRepeated is false next point is not checked this matches JTS behavior
