Function Documentation

bool te::vp::Aggregation	(	const std::string &	inDataset,
		te::da::DataSource *	inDatasource,
		const std::vector< te::dt::Property * > &	groupingProperties,
		const std::map< te::dt::Property *, std::vector< te::stat::StatisticalSummary > > &	statisticalSummary,
		const std::string &	outDataset,
		te::da::DataSource *	outDatasource
	)

Executes the Aggregation Geographical Operation and persists the result as a dataset in a given output datasource.

Parameters

inDataset	The name of the dataset to be used in aggregation operation. It must exists in the input datasource.
inDatasource	Pointer to the datasource that contains the input dataset. Do not pass null.
groupingProperties	Selected properties based on selected layer.
statisticalSummary	Map of selected functions based on input dataset properties.
outDataset	The name for the resulting datasource. It should not exists in the output datasource.
outDatasource	Pointer to the datasource to persist the resulting dataset. Do not pass null.

Returns

True if the it succeeds and false otherwise.

This algorithm assums that the input dataset exists in the datasource. It generates a new dataset in the ouput datasource, do it can not exists a dataset with the same name prior to the calling of this algorithm.

		const std::string &	outDataset,
		te::da::DataSource *	outDatasource,
		const double &	fixedDistance = 0,
		const std::string &	fromAttDistance = ""
	)

Executes the Buffer Geographical Operation and persists the result as a dataset in a given output datasource.

Parameters

inDatasetName	The name of the dataset to be used in aggregation operation. It must exists in the input datasource.
inDatasource	Pointer to the datasource that contains the input dataset. Do not pass null.
bufferPolygonRule	The buffer rule for all geometries (enum RuleForBuffer)
bufferBoundariesRule	The buffer boundaries rule for all geometries (enum BoundariesBetweenBuffers)
copyInputColumns	If boudaries between geometries was not dissolved, the user has the option to Copy de columns from the InputLayer.
levels	The number of levels.
outDatasetName	The name for the resulting datasource. It should not exists in the output datasource.
outDatasource	Pointer to the datasource to persist the resulting dataset. Do not pass null.
fixedDistance	The buffer distance for each geometry with the fixed value.
fromAttDistance	The buffer distance for each geometry is related with a value from one property.

Returns

True if the it succeeds and false otherwise.

This algorithm assums that the input dataset exists in the datasource. It generates a new dataset in the ouput datasource, do it can not exists a dataset with the same name prior to the calling of this algorithm.
