◆ readMeteoData()

void mio::SNIO::readMeteoData	(	const Date &	dateStart,
		const Date &	dateEnd,
		std::vector< std::vector< MeteoData > > &	vecMeteo
	)

virtual

Fill vecMeteo with a time series of objects corresponding to the interval indicated by dateStart and dateEnd.

Matching rules:

if dateStart and dateEnd are the same: return exact match for date
if dateStart > dateEnd: return first data set with date > dateStart
read in all data starting with dateStart until dateEnd
if there is no data at all then the vectors will be empty, no exception will be thrown

Example Usage:

vector< vector<MeteoData> > vecMeteo;      //empty vector
Date d1(2008,06,21,11,0, 1);       //21.6.2008 11:00 UTC+1
Date d2(2008,07,21,11,0, 1);       //21.7.2008 11:00 UTC+1
IOHandler io1("io.ini");
io1.readMeteoData(d1, d2, vecMeteo);

Parameters

dateStart	A Date object representing the beginning of an interval (inclusive)
dateEnd	A Date object representing the end of an interval (inclusive)
vecMeteo	A vector of vector<MeteoData> objects to be filled with data

Reimplemented from mio::IOInterface.

◆ readStationData()

void mio::SNIO::readStationData	(	const Date &	date,
		std::vector< StationData > &	vecStation
	)

virtual

Fill vecStation with StationData objects for a certain date of interest.

Example Usage:

vector<StationData> vecStation;  //empty vector
Date d1(2008,06,21,11,0, 1.);       //21.6.2008 11:00 UTC+1
IOHandler io1("io.ini");
io1.readStationData(d1, vecStation);

Parameters

date	A Date object representing the date for which the meta data is to be fetched
vecStation	A vector of StationData objects to be filled with meta data

Reimplemented from mio::IOInterface.

◆ writeMeteoData()

void mio::SNIO::writeMeteoData	(	const std::vector< std::vector< MeteoData > > &	vecMeteo,
		const std::string &	name = `""`
	)

virtual

Write vecMeteo time series to a certain destination.

Example Usage: Configure the io.ini to use a certain plugin for the output:

METEODEST     = GEOTOP
METEODESTPATH = /tmp
METEODESTSEQ  = Iprec SWglobal

An example implementation (reading and writing):

vector< vector<MeteoData> > vecMeteo;      //empty vector
Date d1(2008,06,21,11,0, 1.);       //21.6.2008 11:00 UTC+1
Date d2(2008,07,21,11,0, 1.);       //21.7.2008 11:00 UTC+1
IOHandler io1("io.ini");
io1.readMeteoData(d1, d2, vecMeteo);
io1.writeMeteoData(vecMeteo)

Parameters

vecMeteo	A vector of vector<MeteoData> objects to be filled with data
name	(optional string) Identifier useful for the output plugin (it could become part of a file name, a db table, etc)

Reimplemented from mio::IOInterface.
