Member Function Documentation

size_t RemoteRaster::_writeData	(	void *	buffer,
		size_t	size,
		size_t	nmemb,
		void *	stream
	)		[static, private]

Callback method for CURL when fetching data.

void RemoteRaster::createRaster	(	const std::string &	str,
		int	categ = 0
	)		[virtual]

Open a raster (read only). Method needed by RasterFactory.

Parameters:

str	WCS string pointing to the raster.
categ	if != 0 this is a categorical map (ie it can't be interpolated). Othewise this is a continuos map.

Needed by RasterFactory.

Reimplemented from GdalRaster.

void RemoteRaster::createRaster	(	const std::string &	str,
		const MapFormat &	format
	)		[virtual]

Create a new raster for projections. If called will throw an exception since the WCS driver in GDAL does not support creation. Method needed by RasterFactory.

Parameters:

str	WCS string pointing to the raster.
format	Output format specification.

Reimplemented from GdalRaster.

Raster * RemoteRaster::CreateRasterCallback

(

)

[static]

RasterFactory calls this function to build a new Raster.

Definition at line 59 of file RemoteRaster.cpp.

int RemoteRaster::deleteRaster

(

)

[virtual]

Method to delete a raster.

Returns:

1 if the raster was successfully deleted, 0 otherwise.

Reimplemented from GdalRaster.

Definition at line 313 of file RemoteRaster.cpp.

References Log::instance(), and Log::warn().

Here is the call graph for this function:

void RemoteRaster::finish

(

)

[virtual]

Event that must be called to indicate when the projection is finished.

Reimplemented from GdalRaster.

Definition at line 303 of file RemoteRaster.cpp.

References Log::instance(), and Log::warn().

Here is the call graph for this function:

bool RemoteRaster::isFromRejectedSource

(

const std::string &

str

)

[static]

Indicates if a remote raster comes from an untrusted source.

RemoteRaster& RemoteRaster::operator=

(

const RemoteRaster &

)

[private]

int RemoteRaster::put	(	Coord	x,
		Coord	y,
		Scalar	val
	)		[virtual]

Put '*val' at the (x,y) coordinate. Returns 0 if (x,y) is out of range or the map is read only. supports only single band output files.

Reimplemented from GdalRaster.

Definition at line 283 of file RemoteRaster.cpp.

References Log::instance(), and Log::warn().

Here is the call graph for this function:

int RemoteRaster::put	(	Coord	x,
		Coord	y
	)		[virtual]

Put 'no data val' at the (x,y) coordinate. Returns 0 if (x,y) is out of range or the map is read only. supports only single band output files.
