		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 ( See te::rst::RasterFactory dictionary for valid registered values ).
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.

		te::gm::Geometry const *const	restrictionGeomPtr,
		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.

void te::rp::FeederConstRasterDirectory::applyGeometryRestriction ( const te::gm::Geometry & restrictionGeom )

Apply a new geometry intersect restriction selecting only those rasters intersecting the given geometry.

Parameters

restrictionGeom The new restrigion geometry.

te::rst::Raster const* te::rp::FeederConstRasterDirectory::getCurrentObj ( ) const

virtual

Return the current sequence object.

Returns: A pointer to the current object or a null pointer if there are no object to return.

Implements te::rp::FeederConstRaster.

unsigned int te::rp::FeederConstRasterDirectory::getCurrentOffset ( ) const

virtual

Return the index of the current object.

Returns: The index of the current object.

Implements te::rp::FeederConstRaster.

const std::string& te::rp::FeederConstRasterDirectory::getCurrentRasterFileName ( )

Returns the current raster file name.

Returns: Returns the current raster file name.

unsigned int te::rp::FeederConstRasterDirectory::getObjsCount ( ) const

virtual

Return the total number of feeder objects.

Returns: The total number of feeder objects.

Implements te::rp::FeederConstRaster.

bool te::rp::FeederConstRasterDirectory::initialize	(	const std::string &	directoryName,
		const bool	recursive,
		const std::string &	rType,
		const bool	sortFileNames,
		const std::vector< std::string > &	fileExtensions,
		te::gm::Geometry const *const	restrictionGeomPtr,
		const bool	ignoreInvalidRasterFiles
	)

protected

Initialize this instance.

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.

bool te::rp::FeederConstRasterDirectory::moveNext ( )

virtual

Advances to the next sequence obeject.

Returns: true if the advance was completed or false if the objects sequence end was reached.

Note: This method can invalidate any pointer returned by getCurrentObj.

Implements te::rp::FeederConstRaster.

bool te::rp::FeederConstRasterDirectory::moveTo ( const unsigned int index )

virtual

Jump to the given object index.

Returns: true if the jump was completed or false on errors.

Note: This method can invalidate any pointer returned by getCurrentObj.

Implements te::rp::FeederConstRaster.

void te::rp::FeederConstRasterDirectory::reset ( )

virtual

Reset the feeder to the first position (subsequent accesses will start from the first sequence obejct).

Note: This method can invalidate any pointer returned by getCurrentObj.

Implements te::rp::FeederConstRaster.
