Detailed Description

template<geometry::OGRWritableGeometry G>
class fishnet::OGRLayerAdapter< G >

Reads and writes a VectorLayer whose geometries are backed by the OGR data source.

Nothing is rebuilt out of the data source on the way in, and nothing is rebuilt point by point on the way out.

See also: fishnet::geometry::OGRLayerGeometry for the geometries this covers, and the adapters' toNative() for getting a fishnet value type back where one is needed.

template<geometry::OGRWritableGeometry G>

static Either< VectorLayer< G >, std::string > fishnet::OGRLayerAdapter< G >::fromOGR ( OGRLayer * ogrLayer )

inlinestatic

Converts an OGRLayer to a fishnet::VectorLayer.

Parameters

ogrLayer pointer to the OGRLayer

Returns: util::Either<VectorLayer<G>, std::string> VectorLayer if successful, error message otherwise

Note: features whose geometry is missing, or of a type a layer of G cannot hold, are skipped

template<geometry::OGRWritableGeometry G>

static OGRwkbGeometryType fishnet::OGRLayerAdapter< G >::layerGeometryType ( )

inlinestatic

WKB type an output layer holding G has to be created with.

template<geometry::OGRWritableGeometry G>

static Either< OGRLayer *, std::string > fishnet::OGRLayerAdapter< G >::toOGR	(	const VectorLayer< G > &	layer,
		OGRLayer *	outputLayer
	)

inlinestatic

Converts a fishnet::VectorLayer to an OGRLayer.

Parameters

layer	vector layer to be converted
outputLayer	inout parameter, should be already created with the correct geometry type and spatial reference

Returns: util::Either<OGRLayer, std::string> OGRLayer if successful, error message otherwise
