Constructor & Destructor Documentation

GMAOFileData::GMAOFileData	(	const string &	name = "",
		const int	geos_version = 0
	)

constructor

Parameters:

	name	the name (path included) of the file to be opened
	geos_version	the geos version of the product. If 0 (default), the class tries to automatically set it

Member Function Documentation

bool GMAOFileData::check_filename

(

const string &

short_filename

)

const [protected]

Check is a the file is a valid meteo data file ( the analysis is done with a filename parsing, not with parsing the data inside )

Parameters:

short_filename

string : the filename without its path

Returns:

bool : true if the filename seems to be valid, false else or in case of problem (exception...)

int GMAOFileData::get_geos_version

(

)

const [inline]

Accessor to the GEOS version.

Returns:

the GEOS major version number

string GMAOFileData::get_product_id

(

)

const [inline]

Accessor to the product ID.

Returns:

the product ID

void GMAOFileData::get_sds_fill_value	(	const string &	sds_name,
		void *	fill_value
	)

read the fill value of the sds given in parametre This overrides the hdffiledata get_sds_fill_value method because in GMAO files, the fill value has a non standard name "missing_value"

Parameters:

	sds_name	the name of the sds where to read the fill value
	fill_value	(output) the read value. Must not be NULL

void GMAOFileData::parse_filename

(

const string &

short_filename

)

[protected]

Once the filename has been checked (that's a precondition : no verification on it are done in this method), some informations can be extracted of it :

• the date
• the hour

  Parameters:

  short_filename

  string : the filename without its path
