Detailed Description

A feeder from an input directory name.

Constructor & Destructor Documentation

te::rp::FeederConstRasterDirectory::FeederConstRasterDirectory	(	const std::string &	directoryName,
		const bool	recursive,
		const std::string &	rType,
		const bool	sortFileNames,
		const std::vector< std::string > &	fileExtensions
	)

Constructor from an input directory name.

Parameters

directoryName	The directory full path name.
recursive	true if a recursive search must be performed.
rType	The name of the specific driver to instantiate each raster.
sortFileNames	If true, the file names will be sorted.
fileExtensions	The file extensions filter (example: ".tif"), or an empty vector if all extensions must be accepted.

		const bool	ignoreInvalidRasterFiles
	)

Constructor from an input directory name with a restriction geometry.

Parameters

directoryName	The directory full path name.
recursive	true if a recursive search must be performed.
rType	The name of the specific driver to instantiate each raster.
sortFileNames	If true, the file names will be sorted.
fileExtensions	The file extensions filter (example: ".tif"), or an empty vector if all extensions must be accepted.
restrictionGeomPtr	A pointer to a restriction geometry (only rasters intercepting this geomtry will be considered) or a null pointer if there is no restriction.
ignoreInvalidRasterFiles	If true, invalid raster files will be ignored.
