Member Function Documentation

public list Geo::OGR::ByteOrders

(

)

Class method.

Returns

a list of byte order types, XDR and NDR. XDR denotes big-endian and NDR denotes little-endian.

Code:

public scalar Geo::OGR::GeometryTypeModify	(	scalar	type,
		scalar	modifier
	)

Parameters

type	a geometry type (one of Geo::OGR::GeometryTypes).
modifier	one of 'flatten', 'set_Z', 'make_collection', 'make_curve', or 'make_linear'.

Returns

modified geometry type.

Code:

public list Geo::OGR::GeometryTypes

(

)

Class method.

Returns

a list of all geometry types, currently: CircularString, CircularStringZ, CompoundCurve, CompoundCurveZ, CurvePolygon, CurvePolygonZ, GeometryCollection, GeometryCollection25D, LineString, LineString25D, LinearRing, MultiCurve, MultiCurveZ, MultiLineString, MultiLineString25D, MultiPoint, MultiPoint25D, MultiPolygon, MultiPolygon25D, MultiSurface, MultiSurfaceZ, None, Point, Point25D, Polygon, Polygon25D, and Unknown.

Code:

public scalar Geo::OGR::GeometryTypeTest	(	scalar	type,
		scalar	test,
		scalar	type2
	)

Parameters

type	a geometry type (one of Geo::OGR::GeometryTypes).
test	one of 'has_z', 'is_subclass_of', 'is_curve', 'is_surface', or 'is_non_linear'.
type2	a geometry type (one of Geo::OGR::GeometryTypes). Required for 'is_subclass_of' test.

Returns

result of the test.

Code:

public Geo::OGR::Driver Geo::OGR::GetDriver

(

scalar

name

)

Parameters

name	a driver name. One of Geo::OGR::GetDriverNames.

Returns

a Geo::OGR::Driver object that represents the internal driver.

Code:

public list Geo::OGR::GetDriverNames

(

)

Returns

a list of the names of available Geo::OGR::Drivers.

Code:

public method Geo::OGR::GetNonLinearGeometriesEnabledFlag

(

)

Code:

public Geo::OGR::DataSource Geo::OGR::GetOpenDS

(

scalar

number

)

Parameters

number

The number of the requested data source.

Returns

a new Geo::OGR::DataSource object.

Code:

public scalar Geo::OGR::GetOpenDSCount

(

)

Returns

the number of all open data sources.

Code:

public method Geo::OGR::OLMD_FID64

(

)

Code:

public Geo::OGR::DataSource Geo::OGR::Open	(	scalar	name,
		scalar	update = 0
	)

Parameters

name	The data source string (directory, filename, etc.).
update	Whether to open the data source in update mode.

Returns

a new Geo::OGR::DataSource object.

Code:

public Geo::OGR::DataSource Geo::OGR::OpenShared	(	scalar	name,
		scalar	update = 0
	)

Parameters

name	The data source string (directory, filename, etc.).
update	Whether to open the data source in update mode.

Returns

a new Geo::OGR::DataSource object.

Code:

public method Geo::OGR::SetGenerate_DB2_V72_BYTE_ORDER

(

scalar

Generate_DB2_V72_BYTE_ORDER

)

Needed only on IBM DB2.
