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:

v

the 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:

	pos	the position at which to insert
	coord	the coordinate to insert
	allowRepeated	if 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
