Class SOLFSMYDataLoader

java.lang.Object

org.orekit.models.earth.atmosphere.data.SOLFSMYDataLoader

All Implemented Interfaces:

DataLoader

public class SOLFSMYDataLoader
extends Object
implements DataLoader

This class reads solar activity data from SOLFSMY files for the class JB2008SpaceEnvironmentData. The code in this class is based of the CssiSpaceWeatherDataLoader.

The data is provided by Space Environment Technologies through their website Link.

The work done for this class is based on the CssiWpaceWeatherDataLoader class by Clément Jonglez, the JB2008 interface by Pascal Parraud, and corrections for DataLoader implementation by Bryan Cazabonne and Evan Ward .

Constructor Detail

SOLFSMYDataLoader

public SOLFSMYDataLoader(TimeScale utc)

Constructor.

Parameters:

Method Detail

getDataSet

public SortedSet<SOLFSMYDataLoader.LineParameters> getDataSet()

Gets the data set.

Returns:

the data set

getMinDate

loadData

public void loadData(InputStream input,
                     String name)
              throws IOException,
                     ParseException,
                     OrekitException

Load data from a stream.

Specified by:

loadData in interface DataLoader

Parameters:

input - data input stream

name - name of the file (or zip entry)

Throws:

IOException - if data can't be read

ParseException - if data can't be parsed or if some loader specific error occurs

OrekitException

stillAcceptsData

public boolean stillAcceptsData()

Check if the loader still accepts new data.

This method is used to speed up data loading by interrupting crawling the data sets as soon as a loader has found the data it was waiting for. For loaders that can merge data from any number of sources (for example JPL ephemerides or Earth Orientation Parameters that are split among several files), this method should always return true to make sure no data is left over.

Specified by:

stillAcceptsData in interface DataLoader

Returns:

true while the loader still accepts new data
