Member Function Documentation

void te::sa::SpatialWeightsExchanger::associateGeometry ( te::sa::GeneralizedProximityMatrix *  gpm, te::da::DataSource *  ds  )

protected

Function used to associate the geometry coord attribute to vertex objects.

Parameters

g	Pointer to a valid graph
ds	Pointer to a valid data source

void te::sa::SpatialWeightsExchanger::exportToGAL	(	te::sa::GeneralizedProximityMatrix *	gpm,
		std::string	pathFileName
	)

Function used to export a gpm to Spatial Weights File GAL Format.

Parameters

gpm	Pointer to a valid graph
pathFileName	Path and file name (with extension) for file creation.

void te::sa::SpatialWeightsExchanger::exportToGWT	(	te::sa::GeneralizedProximityMatrix *	gpm,
		std::string	pathFileName,
		int	distAttrIdx
	)

Function used to export a gpm to Spatial Weights File GWT Format.

Parameters

gpm	Pointer to a valid graph
pathFileName	Path and file name (with extension) for file creation.
distAttrIdx	Edge Atrribute index with distance information

int te::sa::SpatialWeightsExchanger::getEdgeId ( )

protected

Function used to generated the edge id.

Returns

Integer value as ID

static void te::sa::SpatialWeightsExchanger::getSpatialWeightsFileInfo ( std::string  pathFileName, std::string &  dataSetName, std::string &  attrName  )

static

Function used to get information of how a Spatial Weights was generated.

Parameters

pathFileName	Path and file name (with extension) with Spatial Weights information.
dataSetName	Information about the dataset used to generate this file.
attrName	Information about the attribute used to generate this file.

Returns

A Valid gpm pointer if the file was correctly readed and null pointer in other case.

te::sa::GeneralizedProximityMatrix* te::sa::SpatialWeightsExchanger::importFromGAL	(	std::string	pathFileName,
		te::da::DataSource *	ds = 0
	)

Function used to import a gpm from a Spatial Weights File GAL Format.

Parameters

pathFileName	Path and file name (with extension) with Spatial Weights information.
ds	Pointer to a datasource in case the gal file has the shapefile information.

Returns

A Valid gpm pointer if the file was correctly readed and null pointer in other case.

te::sa::GeneralizedProximityMatrix* te::sa::SpatialWeightsExchanger::importFromGWT	(	std::string	pathFileName,
		te::da::DataSource *	ds = 0
	)

Function used to import a gpm from a Spatial Weights File GWT Format.

Parameters

pathFileName	Path and file name (with extension) with Spatial Weights information.
ds	Pointer to a datasource in case the gwt file has the shapefile information.

Returns

A Valid gpm pointer if the file was correctly readed and null pointer in other case.
