Constructor & Destructor Documentation

◆ AbstractOperation()

te::vp::AbstractOperation::AbstractOperation ( const std::string & operationName )

Default constructor.

Note: This class will take the ownership of AbstractParameters pointer

◆ ~AbstractOperation()

virtual te::vp::AbstractOperation::~AbstractOperation ( )

virtual

Virtual destructor.

Initializes the operation input and output

Member Function Documentation

◆ abort()

void te::vp::AbstractOperation::abort ( )

Returns TRUE if the operation has been aborted. FALSE otherwise.

◆ addOutputColumns()

virtual void te::vp::AbstractOperation::addOutputColumns ( te::da::DataSetType * outputDataSetType )

protectedvirtual

Initializes the operation input.

◆ createBasicOutputDataSetType()

virtual te::da::DataSetType* te::vp::AbstractOperation::createBasicOutputDataSetType	(	const std::string &	dataSetName,
		int	srid,
		te::gm::GeomType	geometryType,
		const std::string &	geometryColumnName
	)		const

protectedvirtual

< Creates the basic dataSetType for the output containing all the columns that are required

Reimplemented in te::vp::SubdivideOperation.

◆ createOutputFeature()

virtual te::vp::Feature* te::vp::AbstractOperation::createOutputFeature ( std::size_t outputIndex )

virtual

It creates the output feature based on the given output dataaccess index.

Parameters

outputIndex The index of the output dataAccess.

◆ execute()

virtual std::vector<te::vp::FeatureSet> te::vp::AbstractOperation::execute ( const std::vector< te::vp::FeatureSet > & vecInput )

virtual

It executes the operation.

Parameters

input Input vector data to be processed.

Precondition: The parameters must be valid (internal check)

Exceptions

Exception It throws an exception if something goes wrong during the execution.

\Return The output memory data processed.

◆ executeImpl()

virtual std::vector<te::vp::FeatureSet> te::vp::AbstractOperation::executeImpl ( const std::vector< te::vp::FeatureSet > & vecInput )

protectedpure virtual

Implemented in te::vp::SubdivideOperation, te::vp::MakeValidOperation, te::vp::IdentityOperation, te::vp::UnionOperation, te::vp::IntersectionOperation, te::vp::DissolveSubdivisionOperation, te::vp::DissolveOperation, and te::vp::DifferenceOperation.

◆ getCapabilities()

virtual std::unique_ptr<te::vp::AbstractOperationCapabilities> te::vp::AbstractOperation::getCapabilities ( ) const

virtual

Makes all the necessaries adaptations to the input dataAccess to avoid duplicate column names.

Reimplemented in te::vp::SubdivideOperation, te::vp::MakeValidOperation, te::vp::DissolveSubdivisionOperation, and te::vp::DissolveOperation.

◆ getDataSetType()

virtual const te::da::DataSetType* te::vp::AbstractOperation::getDataSetType ( std::size_t outputIndex )

virtual

Gets the dataSetType of the 'outputIndex-th' output.

Parameters

outputIndex The index of the output dataAccess. Sets the parameters to be used by the operation

◆ getName()

const std::string& te::vp::AbstractOperation::getName ( ) const

Gets the output geometry type.

◆ getOutputGeometryType()

te::gm::GeomType te::vp::AbstractOperation::getOutputGeometryType ( ) const

Aborts the execution of the operation.

◆ getParameters()

AbstractParameters* te::vp::AbstractOperation::getParameters ( ) const

Gets the operation report.

◆ getReport()

OperationReport* te::vp::AbstractOperation::getReport ( ) const

Gets the operation name.

◆ handleOutputPropertyNamesChanges()

bool te::vp::AbstractOperation::handleOutputPropertyNamesChanges	(	const te::da::DataSetType *	baseOutputDataSetType,
		const te::da::DataSetType *	actualOutputDataSetType
	)

◆ initialize()

virtual void te::vp::AbstractOperation::initialize ( )

virtual

Reimplemented in te::vp::UnionOperation, and te::vp::IdentityOperation.

◆ initializeInput()

virtual bool te::vp::AbstractOperation::initializeInput ( )

protectedvirtual

Initializes the operation output.

◆ initializeOutput()

virtual bool te::vp::AbstractOperation::initializeOutput ( )

protectedvirtual

Function that effectivelly executes the operation. It must be implemented by the concrete classes.

◆ isAborted()

bool te::vp::AbstractOperation::isAborted ( ) const

Get the capabilities of the operation. Basically, operation will have 2 inputs, 1 output, and support subdivision. If it is not the case of the concrete class, this function should be overriden.

◆ prepareInputData()

bool te::vp::AbstractOperation::prepareInputData ( )

◆ prepareOutputData()

bool te::vp::AbstractOperation::prepareOutputData ( )

◆ setParameters()

void te::vp::AbstractOperation::setParameters ( AbstractParameters * params )

Gets the operation current parameters.

◆ m_aborted

bool te::vp::AbstractOperation::m_aborted

protected

Becames true if the abort function is called. Concrete classes must check for this value from time to time.

Definition at line 297 of file AbstractOperation.h.

AbstractOperationImpl* te::vp::AbstractOperation::m_impl

protected

Holds all the attributes of the class.
