te::vp::BufferQuery::BufferQuery ( )

Default constructor.

◆ ~BufferQuery()

te::vp::BufferQuery::~BufferQuery ( )

Destructor.

Member Function Documentation

◆ dissolveQuery()

std::vector<std::vector<te::gm::Geometry*> > te::vp::BufferQuery::dissolveQuery	(	te::da::DataSet *	dsQuery,
		const int &	levels
	)

protected

It dissolves the bounders between buffers.

Parameters

outDSet	The dataSet with buffers.
levels	The number of levels the dataset has.

Note: The outDSet is updated with dissolved buffers.

◆ GetDataSetType()

te::da::DataSetType* te::vp::BufferOp::GetDataSetType ( )

protectedinherited

It builds the output DataSetType.

◆ paramsAreValid()

virtual bool te::vp::BufferOp::paramsAreValid ( )

virtualinherited

It verifies if the parameters are valid.

Returns: A Boolean value that means if the operation successfully completed or not.

◆ prepareDataSet() [1/2]

void te::vp::BufferQuery::prepareDataSet	(	std::vector< std::vector< te::gm::Geometry * > >	vecDissolvedGeom,
		te::mem::DataSet *	outputDataSet,
		const int &	sourceSRID,
		const double &	distance
	)

protected

It prepare the dataset to be persisted with dissolved geometries.

Parameters

vecDissolvedGeom	A vecter with dissolved geometries by level.
outputDataSet	The dataSet prepared to be persisted.
distance	The buffer distance.

Note: The outDSet is updated with dissolved buffers.

◆ prepareDataSet() [2/2]

void te::vp::BufferQuery::prepareDataSet	(	te::da::DataSet *	dataSetQuery,
		te::mem::DataSet *	outputDataSet,
		const int &	sourceSRID
	)

protected

It prepare the dataset to be persisted.

Parameters

dataSetQuery	The dataSet that was returned by query.
outputDataSet	The dataSet prepared to be persisted.

◆ run()

bool te::vp::BufferQuery::run ( )

virtual

It executes the operation.

Returns: A Boolean value that means if the operation successfully completed or not.

Implements te::vp::BufferOp.

◆ setInput()

void te::vp::BufferOp::setInput	(	te::da::DataSourcePtr	inDsrc,
		std::string	inDsetName,
		std::unique_ptr< te::da::DataSetTypeConverter >	converter,
		const te::da::ObjectIdSet *	oidSet = `0`
	)

inherited

It sets the input data will be calculated.

Parameters

inDsrc	Where data is located.
inDsetName	DataSet name.
converter	DataSetTypeConverterr.
oidSet	ObjectIdSet - It is necessary if has need to execute with a set of specific objects

◆ setOutput()

void te::vp::BufferOp::setOutput	(	te::da::DataSourcePtr	outDsrc,
		std::string	dsname
	)

inherited

It sets the output parameters that will be used to persist operation result.

Parameters

outDsrc	Where data is will be persisted.
dsname	The name os output data.

Note: The output name must be different from other data that is already in dataSource.

◆ setParams()

void te::vp::BufferOp::setParams	(	const double &	distance,
		const int &	newSrid,
		const int &	bufferPolygonRule,
		const int &	bufferBoundariesRule,
		const bool &	copyInputColumns,
		const int &	levels,
		const int &	attributePosition = `-1`
	)

inherited

It sets the input parameters that will be consumed to execute the operation.

Parameters

distance	A numeric value to set a fixed distance to buffer.
bufferPolygonRule	The rule used for buffer result (INSIDE_OUTSIDE = 0, ONLY_OUTSIDE = 1, ONLY_INSIDE = 2).
bufferBoundariesRule	The BoundariesBetweenBuffers can be dissolved or not - (DISSOLVE = 0 and NOT_DISSOLVE = 1).
copyInputColumns	Copy columns from input DataSet.
levels	The number of levels buffer will have.
attributePosition	The buffer can be calculated by attribute values. The attribute must be numeric type.

Note: If uses attibutePosition parameter, the fixed distance will be ignored.; The attributePosition parameter must be numeric type.; If there is a null value or zero in chosen attribute, the line that has this value will be ignored.
