Detailed Description

Models a collection of Point objects.


Constructor & Destructor Documentation

geos::geom::MultiPoint::MultiPoint std::vector< Geometry * > *  newPoints,
const GeometryFactory newFactory
[protected]
 

Constructs a MultiPoint.

Parameters:
newPoints the Points for this MultiPoint, or null or an empty array to create the empty geometry. Elements may be empty Points, but not nulls.
Constructed object will take ownership of the vector and its elements.

Parameters:
newFactory The GeometryFactory used to create this geometry Caller must keep the factory alive for the life-time of the constructed MultiPoint.


Member Function Documentation

Geometry* geos::geom::MultiPoint::clone  )  const [inline, virtual]
 

Creates and returns a full copy of this GeometryCollection object. (including all coordinates contained by it).

Returns:
a clone of this instance

Reimplemented from geos::geom::GeometryCollection.

Geometry* geos::geom::MultiPoint::getBoundary  )  const [virtual]
 

Gets the boundary of this geometry.

Zero-dimensional geometries have no boundary by definition, so an empty GeometryCollection is returned.

Returns:
an empty GeometryCollection
See also:
Geometry::getBoundary

Reimplemented from geos::geom::GeometryCollection.
