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

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

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.

		const int &	bufferPolygonRule,
		const int &	bufferBoundariesRule,
		const bool &	copyInputColumns,
		const int &	levels,
		const int &	attributePosition = `-1`
	)

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.
