Geometry * | getBoundary () const
| Returns a MultiLineString composed of one LineString for each of the composing Polygon's shells and holes.
std::string | getGeometryType () const
| Return a string representation of this Geometry type.
virtual GeometryTypeId | getGeometryTypeId () const
| Return an integer representation of this Geometry type.
bool | isSimple () const
| Returns false if the Geometry not simple.
bool | equalsExact (const Geometry *other, double tolerance=0) const
| Returns true if the two Geometrys are exactly equal, up to a specified tolerance.
Geometry * | clone () const
| Make a deep-copy of this Geometry.

## Detailed Description

Basic implementation of `MultiPolygon`.

## Constructor & Destructor Documentation

geos::geom::MultiPolygon::MultiPolygon | ( | std::vector< Geometry * > * | newPolys,
|  | const GeometryFactory * | newFactory |
| ) |  |  | `[protected]`

Construct a MultiPolygon.

Parameters:

  | newPolys | the `Polygon`s for this `MultiPolygon`, or `null` or an empty array to create the empty geometry. Elements may be empty `Polygon`s, but not `null`s. The polygons must conform to the assertions specified in the OpenGIS Simple Features Specification for SQL .

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 MultiPolygon.
