## 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 `Point`s for this `MultiPoint`, or `null` or an empty array to create the empty geometry. Elements may be empty `Point`s, but not `null`s.

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

  Geometry::getBoundary

Reimplemented from geos::geom::GeometryCollection.
