createCollectionOfType()

std::unique_ptr< QgsGeometryCollection > QgsGeometryFactory::createCollectionOfType ( Qgis::WkbType  type )

static

Returns a new geometry collection matching a specified WKB type.

For instance, if type is PolygonM the returned geometry will be a QgsMultiPolygon with M values.

Definition at line 264 of file qgsgeometryfactory.cpp.

fromMultiPointXY()

std::unique_ptr< QgsMultiPoint > QgsGeometryFactory::fromMultiPointXY ( const QgsMultiPointXY &  multipoint )

static

Construct geometry from a multipoint.

Definition at line 144 of file qgsgeometryfactory.cpp.

fromMultiPolygonXY()

std::unique_ptr< QgsMultiPolygon > QgsGeometryFactory::fromMultiPolygonXY ( const QgsMultiPolygonXY &  multipoly )

static

Construct geometry from a multipolygon.

Definition at line 197 of file qgsgeometryfactory.cpp.

fromMultiPolylineXY()

std::unique_ptr< QgsMultiLineString > QgsGeometryFactory::fromMultiPolylineXY ( const QgsMultiPolylineXY &  multiline )

static

Construct geometry from a multipolyline.

fromPointXY()

std::unique_ptr< QgsAbstractGeometry > QgsGeometryFactory::fromPointXY ( const QgsPointXY &  point )

static

Construct geometry from a point.

Definition at line 139 of file qgsgeometryfactory.cpp.

fromPolygonXY()

std::unique_ptr< QgsPolygon > QgsGeometryFactory::fromPolygonXY ( const QgsPolygonXY &  polygon )

static
