 MultiPolygon (vector< Geometry * > *newPolys, const GeometryFactory *newFactory)
 Construct a MultiPolygon.
int getDimension () const
 Returns surface dimension (2).
int getBoundaryDimension () const
 Returns 1 (MultiPolygon boundary is MultiLineString).
GeometrygetBoundary () const
 Returns a MultiLineString composed of one LineString for each of the composing Polygon's shells and holes.
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) const
 Returns true if the two Geometrys are exactly equal, up to a specified tolerance.


Detailed Description

Basic implementation of MultiPolygon.

Constructor & Destructor Documentation

geos::MultiPolygon::MultiPolygon ( vector< Geometry * > *  newPolys,
const GeometryFactory factory 
)

Construct a MultiPolygon.

Parameters:
newPolys the Polygons for this MultiPolygon, or null or an empty array to create the empty geometry. Elements may be empty Polygons, but not nulls. 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.
newPolys the Polygons for this MultiPolygon, or null or an empty array to create the empty geometry. Elements may be empty Polygons, but not nulls. 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.
