CsvTask

public CsvTask(String path)

Creates a CSV exporting task that's meant to store its values in the file specified by path.

Parameters:

path - File to write to. Cannot be null.

Method Details

doInBackground

public String doInBackground()

Does the work of exporting and formatting CSV values from a MultiSpectralControl in a background thread.

Specified by:

doInBackground in class SwingWorker<String,Object>

Returns:

String representing the contents to write to a CSV file. May be null.

done

protected void done()

Called (on the event dispatch thread) when doInBackground() has completed.

Overrides:

done in class SwingWorker<String,Object>

writeToPath

private void writeToPath(String csvContents)

Write the given string to path.

Parameters:

csvContents - CSV file contents. Should not be null.

collectValues

private double[][] collectValues(double[] wavelengths)
                          throws VisADException,
RemoteException

Iterates through each channel/wavenumber and extracts the value of the existing ReadoutProbes at their current positions.

Be warned, this can be slow when there are thousands of channels. Definitely do not run this method on the event dispatch thread.

Parameters:

wavelengths - Array containing all the channels/wavenumbers. Cannot be null.

Returns:

Two-dimensional array of doubles. First array represents the probes, second dimension is the value of a probe at each channel/wavenumber.

Throws:

VisADException - if there was a problem

RemoteException - if there was somehow an RMI problem

exportSpectra

private String exportSpectra()
                      throws Exception

Coordinates the collecting of probe data as well as creating a string representing the contents of the CSV file.

Returns:

String value that can be written to a CSV file.

Throws:

Exception - if there was some problem
