Detailed Description

Container class for geospatial vector data, represented by an OGR datasource.

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]FilePathThe path of the file(s).
[in]FileNameThe 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,
unsigned int  LayerIndex = 0

Exceptions
openfluid::base::FrameworkExceptionif OGR doesn't succeed to open the datasource.
OGRDataSource* openfluid::core::GeoVectorValue::data ( )

Gets the associated opened OGR datasource in read-only access. If the datasource is not already opened, tries to open it first.

Returns
The opened OGR datasource.
Exceptions
openfluid::base::FrameworkExceptionif OGR doesn't succeed to open the datasource.
void openfluid::core::GeoVectorValue::destroyDataSource ( )
protected

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]LayerIndexThe index of the layer to query, default 0.
[in]FieldNameThe name of the field to query.
Returns
The index of FieldName or -1 if field FieldName doesn't exist.
Exceptions
openfluid::base::FrameworkExceptionif 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,
unsigned int  LayerIndex = 0 
)

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

Parameters
[in]FieldNameThe name of the field to query.
[in]FieldTypeThe type of the field to query.
[in]LayerIndexThe index of the layer to query, default 0.
Returns
True if the field FieldName is type FieldType.
Exceptions
openfluid::base::FrameworkExceptionif the field doesn't exist.
openfluid::base::FrameworkExceptionif 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
[in]LayerIndexThe index of the layer to compare the type, default 0.
Returns
True if the type of the layer LayerIndex is wkbLineString, false otherwise.
Exceptions
openfluid::base::FrameworkExceptionif OGR doesn't succeed to open the datasource.
bool openfluid::core::GeoVectorValue::isMultiLineType ( unsigned int  LayerIndex = 0)

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

Parameters
[in]LayerIndexThe index of the layer to compare the type, default 0.
Returns
True if the type of the layer LayerIndex is wkbMultiLineString, false otherwise.
Exceptions
openfluid::base::FrameworkExceptionif OGR doesn't succeed to open the datasource.
bool openfluid::core::GeoVectorValue::isMultiPointType ( unsigned int  LayerIndex = 0)

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