Detailed Description

provides a set of converter function between DM and generic memory manager structures

Function Documentation

asColBuffer() [1/2]

DM_API int64_t DM::GenericConverter::asColBuffer	(	IColBufferManagerWrite &	colBufferManager,
		const_iterator_point	it,
		const_iterator_point	end,
		const AddInfoLayoutHandle &	layout,
		bool	withCoordinates = true,
		AddInfoHandle	noDataValues = AddInfoHandle(),
		bool	useNoDataMask = false,
		FilterHandle	filter = FilterHandle()
	)

initialize and fill a column buffer manager this function combines initColBufferManager and fillColBuffer calls. The number of rowCounts that is needed to store all data is internally determined and passed to the colBufferManager object before the actual filling is performed

Parameters

[in]	colBufferManager	column buffer manager object for allocating the necessary column buffer objects
[in]	it	begin iterator of points
[in]	end	end iterator of points
[in]	layout	defines the attributes (columns of the data frame object) to that should be generated
[in]	withCoordinates	flag if columns for the coordinates should generated as well
[in]	noDataValues	object that contains no data values for attributes (layout has to match parameter layout)
[in]	useNoDataMask	flag if a separate no data flag memory array is used instead of no data values
[in]	filter	optional filter to subselect the points

Returns

number of rows that were filled

asColBuffer() [2/2]

DM_API int64_t DM::GenericConverter::asColBuffer	(	IColBufferManagerWrite &	colBufferManager,
		const_iterator_point	it,
		const_iterator_point	end,
		int64_t	rowCount,
		const AddInfoLayoutHandle &	layout,
		bool	withCoordinates = true,
		AddInfoHandle	noDataValues = AddInfoHandle(),
		bool	useNoDataMask = false,
		FilterHandle	filter = FilterHandle()
	)

initialize and fill a column buffer manager this function combines initColBufferManager and fillColBuffer calls. In this function the number of rows needs to be provided in rowCount to store all data. Its is also passed to the colBufferManager object before the actual filling is performed

Parameters

[in]	colBufferManager	column buffer manager object for allocating the necessary column buffer objects
[in]	it	begin iterator of points
[in]	end	end iterator of points
[in]	rowCount	number of rosw to be excepted (needs to match the number of points that will be filled in)
[in]	layout	defines the attributes (columns of the data frame object) to that should be generated
[in]	withCoordinates	flag if columns for the coordinates should generated as well
[in]	noDataValues	object that contains no data values for attributes (layout has to match parameter layout)
[in]	useNoDataMask	flag if a separate no data flag memory array is used instead of no data values
[in]	filter	optional filter to subselect the points

Returns

number of rows that were filled

initColBufferManager()

DM_API void DM::GenericConverter::initColBufferManager	(	IColBufferManagerWrite &	colBufferManager,
		int64_t	rowCount,
		const AddInfoLayoutHandle &	layout,
		bool	withCoordinates = true,
		AddInfoHandle	noDataValues = AddInfoHandle(),
		bool	useNoDataMask = false
	)

initialize a column buffer manager that it can be used for subsequent converter calls

Parameters

[in]	colBufferManager	column buffer manager object for allocating the necessary column buffer objects
[in]	rowCount	number of rows to reserve
[in]	layout	defines the attributes (columns of the data frame object) to that should be generated
[in]	withCoordinates	flag if columns for the coordinates should generated as well
[in]	noDataValues	object that contains no data values for attributes (layout has to match parameter layout)
[in]	useNoDataMask	flag if a separate no data flag memory array is used instead of no data values
