Constructor & Destructor Documentation

GeometryCollection()

template<typename TCoordinates >

mongo::geo::GeometryCollection< TCoordinates >::GeometryCollection ( const BSONObj &  bson )

explicit

GeometryCollection constructor.

Parameters

bson	A BSON representation of the geometry collection.

Member Function Documentation

getBoundingBox()

template<typename TCoordinates >

BoundingBox< TCoordinates > mongo::geo::GeometryCollection< TCoordinates >::getBoundingBox

virtual

Obtain the bounding box surrounding the set of geometries in this geometry collection.

Returns

A bounding box containing every geometry in this collection.

Implements mongo::geo::GeoObj< TCoordinates >.

getGeometries()

template<typename TCoordinates >

const std::vector< const GeoObj< TCoordinates > * > & mongo::geo::GeometryCollection< TCoordinates >::getGeometries

Get a vector of pointers to the geometries contained in this geometry collection.

Each GeoObj has been instantiated as the appropriate subclass of GeoObj. To determine the specific type of each pointed-to object, call ->getType() on the pointer.

This GeometryCollection object has ownership of the const GeoObj*'s returned.

Returns

a vector of const pointers to the geometries in this collection.

getType()

template<typename TCoordinates >

virtual GeoObjType mongo::geo::GeometryCollection< TCoordinates >::getType ( ) const

inlinevirtual

Get the geometry type of this object.

Returns

GeoObjType_GeometryCollection

Implements mongo::geo::GeoObj< TCoordinates >.

toBSON()

template<typename TCoordinates >

virtual BSONObj mongo::geo::GeometryCollection< TCoordinates >::toBSON ( ) const

inlinevirtual

Obtain a BSON representation of this geometry collection.

Example structure:

{ "type" : "GeometryCollection", "geometries" : [ { "type": "Point", "coordinates": [ 100.0, 0.0 ] }, { "type": "LineString", "coordinates": [ [ 101.0, 0.0 ], [ 102.0, 1.0 ] ] } ] }

Returns

a BSON representation of this geometry collection.

Implements mongo::geo::GeoObj< TCoordinates >.
