Constructor & Destructor Documentation

openfluid::core::GeoVectorValue::GeoVectorValue	(	const std::string &	FilePath,
		const std::string &	FileName
	)

Creates a new value. For ESRI Shapefile, the FileName may be the name of a .shp, .shx or .dbf file, or a path to a directory containing proper shape files. It doesn't open the associated OGR datasource.

Parameters

[in]	FilePath	The path of the file(s).
[in]	FileName	The name or the relative path of the file to open.

openfluid::core::GeoVectorValue::~GeoVectorValue ( )

Destructor. Closes the open OGR datasource.

Member Function Documentation

bool openfluid::core::GeoVectorValue::containsField	(	const std::string &	FieldName,

Destroy the OGRDataSource.

int openfluid::core::GeoVectorValue::getFieldIndex	(	const std::string &	FieldName,
		unsigned int	LayerIndex = `0`
	)

Gets the index of a field in the LayerIndex layer.

Parameters

[in]	LayerIndex	The index of the layer to query, default 0.
[in]	FieldName	The name of the field to query.

Returns: The index of FieldName or -1 if field FieldName doesn't exist.

Exceptions

openfluid::base::FrameworkException if OGR doesn't succeed to open the datasource.

openfluid::core::UnstructuredValue::UnstructuredType openfluid::core::GeoVectorValue::getType ( ) const

virtual

Returns the type of this GeoVectorValue.

Implements openfluid::core::UnstructuredValue.

bool openfluid::core::GeoVectorValue::isFieldOfType	(	const std::string &	FieldName,
		OGRFieldType	FieldType,

	)

Returns true if a field is of the type FieldType in the LayerIndex layer.

Parameters

[in]	FieldName	The name of the field to query.
[in]	FieldType	The type of the field to query.
[in]	LayerIndex	The index of the layer to query, default 0.

Returns: True if the field FieldName is type FieldType.

Exceptions

openfluid::base::FrameworkException	if the field doesn't exist.
openfluid::base::FrameworkException	if OGR doesn't succeed to open the datasource.

bool openfluid::core::GeoVectorValue::isLineType ( unsigned int LayerIndex = 0 )

Returns true if the GeoVectorValue is line type, false otherwise.

Parameters
