Constructor Details

PolarOrbitTrackDataSource

public PolarOrbitTrackDataSource()

Default bean constructor for persistence; does nothing.

PolarOrbitTrackDataSource

public PolarOrbitTrackDataSource(DataSourceDescriptor descriptor,
 String filename,
 Hashtable properties)

Create a new PolarOrbitTrackDataSource

Parameters:

descriptor - descriptor for this source

filename - ADDE URL

properties - extra properties for this source

Method Details

makeNameForRemoteSource

public static String makeNameForRemoteSource(String urlStr)

Create a nice looking name for this instance.

Given a URL like http://celestrak.com/NORAD/elements/weather.txt, this method will return celestrak: /NORAD/elements/weather.txt.

If the hostname from urlStr could not be sufficiently reduced, this method will simply use the entire hostname. A URL like http://adde.ssec.wisc.edu/weather.txt will return adde.ssec.wisc.edu: weather.txt.

If there was a problem parsing urlStr, the method will try to return the filename. A URL like http://celestrak.com/NORAD/elements/weather.txt would return weather.txt.

If all of the above fails, urlStr will be returned.

Parameters:

urlStr - URL of the TLE information. Cannot be null.

Returns:

Either the name as described above, or null if there was a problem.

checkFirstEntry

private void checkFirstEntry()

checksum

private int checksum(String str)

decodeCard1

private int decodeCard1(String card)

decodeCard2

private int decodeCard2(String card)

doMakeDataChoices

protected void doMakeDataChoices()

Make the data choices associated with this source.

Overrides:

doMakeDataChoices in class DataSourceImpl

getDataInner

protected Data getDataInner(DataChoice dataChoice,
 DataCategory category,
 DataSelection dataSelection,
 Hashtable requestProperties)
                     throws VisADException,
RemoteException

Actually get the data identified by the given DataChoce. The default is to call the getDataInner that does not take the requestProperties. This allows other, non unidata.data DataSource-s (that follow the old API) to work.

Overrides:

getDataInner in class DataSourceImpl

Parameters:

dataChoice - The data choice that identifies the requested data.

category - The data category of the request.

dataSelection - Identifies any subsetting of the data.

requestProperties - Hashtable that holds any detailed request properties.

Returns:

The visad.Text object

Throws:

RemoteException - Java RMI problem

VisADException - VisAD problem

getDouble

private double getDouble(int beg,
 int end,
 String card)

getDTime

public int getDTime()

getInt

private int getInt(int beg,
 int end,

public void setChoices(ArrayList<String> choices)

choices needs to persist to support bundles

Parameters:

choices - the choices to set

getTleCards

public ArrayList<String> getTleCards()

tleCards needs to persist to support bundles

Returns:

the tleCards

setTleCards

public void setTleCards(ArrayList<String> tleCards)

tleCards needs to persist to support bundles

Parameters:

loadId - For stopping the load through the JobManager

changeLinks - Should this data source also change its internal data references

Returns:

List of the files that were written

Throws:

Exception - On badness
