Constructor Detail

FechnerDriver

public FechnerDriver(Map<String,String> info)

Constructor. Does not open the connection, this is done in init().

Method Detail

init

public void init()
          throws InitException

On init, we default the initial read-out window to the chip size.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractCcdDriver

Throws:

InitException

openController

protected boolean openController()
                          throws IOException

Initializes an RPC driver. Tries to connect to the server via tcp/ip.

Specified by:

openController in class AbstractCcdDriver

Returns:

False If controller could not be opened.

Throws:

IOException - If controller connection fails.

isOpen

public boolean isOpen()

We consider the driver to be open if the ccdclient is initialized.

Returns:

True, if a previous initialization was successful

close

public boolean close()
              throws IOException

Close the RPC communication.

Returns:

True if clean-up was successful.

Throws:

IOException

getCcdInfo

public Map<String,Object> getCcdInfo()

This ccd does not provide any additional info.

expose

public int expose()
           throws IOException

Make an exposure. The exposure time and the data buffer must be set prior to a call to this function. Note that this method does not check for proper settings. In TF's driver this method blocks.

Returns:

Number of pixel writtn.

Throws:

IOException - Any subclass of IOException.

See Also:

startExpose

exposeBias

public int exposeBias()
               throws IOException

Makes a bias exposure. If bias is not supported by the driver directly, this should be indicated by the #KEY_SUPPORTBIAS key set to false. In the latter case, this method thros an UnsupportedOperationException.

The data buffer has to be set prior to a call to this method.

Returns:

Number of pixel writtn.

Throws:

IOException - Any subclass of IOException.

exposeDark

public int exposeDark()
               throws IOException

Makes a dark exposure. If dark is not supported by the driver, e.g. if no shutter is present, this should be indicated by the #KEY_SUPPORTDARK key set to false. In the latter case, this method thros an UnsupportedOperationException.

The data buffer has to be set prior to a call to this method.

Returns:

Number of pixel writtn..

Throws:

IOException - Any subclass of IOException.

setFileBuffer

public boolean setFileBuffer(String file)
                      throws IOException

Sets the output buffer. Currently, only writing to a file is supported. If the argument passed to this method is not a File or URL object, a ClassCastException is thrown. In case of invoking this method with an URL, only the file part is kept.

Throws:

IOException

getData

public MFits getData()
              throws IOException

Returns the output buffer. In this driver, we query for the fits file name. If we are incrementing, we try to guess the correct file name by appending -0000n, n being the internal fits counter, to the file name returned. An ending #FITS is appended. Return type is of String. Can be used with a class loader to find the resource.

Throws:

IOException - Any subclass of IOException.

setBinning

public boolean setBinning(int xbin,
                          int ybin)
                   throws IOException

Set the binning values in x (columns) and y (rows).

Parameters:

xbin - binning factor in x-direction (1 <= binning factor <= 255)

ybin - binning factor in y-direction (1 <= binning factor <= 255)

Returns:

True if successful.

Throws:

IOException - Any subclass of IOException

getBinning

public Dimension getBinning()
                     throws IOException

Get the binning values in x (columns) and y (rows).

Returns:

Dimension object, columns in width.

Throws:

IOException - Any subclass of IOException.

setWindow

public boolean setWindow(Rectangle window)
                  throws IOException

Set the current image window.

Parameters:

window - The origin being the upper left corner of the rectangle.

Returns:

True if successful.

Throws:

IOException - Any subclass of IOException.

getWindow

public Rectangle getWindow()
                    throws IOException

Get the current image origin (pre-gap) in x (columns) and y (rows) and the size

Returns:

A rectangle with pre-gap upper left corner.

Throws:

IOException - Any subclass of IOException.

setExposureTime

public boolean setExposureTime(double exptime)
                        throws IOException

Set the current exposure time in milliseconds.

Parameters:

expTime - exposure time in milliseconds. (0 <= expTime < 65536 ms)

Returns:

True if successful.

Throws:

IOException - Any subclass of IOException.

getExposureTime

public double getExposureTime()
                       throws IOException

Get the current exposure time in milliseconds.

Returns:

current exposure time (in milliseconds).

Throws:

IOException - Any subclass of IOException.

clearArguments

protected void clearArguments()

Initalizies the RPC function arguments.

setMaxPixel

protected boolean setMaxPixel(Dimension max)
                       throws IOException

Set the max_pixel values for x (columns) and y (rows).

Parameters:

xmax - maximum CCD size in x-direction (1 <= value < 65536)

ymax - maximum CCD size in y-direction (1 <= value < 65536)

Throws:

IOException

getMaxPixel

protected Dimension getMaxPixel()
                         throws IOException

Get the max_pixel values for x (columns) and y (rows).

Returns:

A dimension object, where the size in x is the width.

Throws:

IOException

setFitsName

protected boolean setFitsName(String filename)
                       throws IOException

Set the current name of the output FITS file.

Parameters:

fileName - output FITS filename.

Throws:

IOException

setFitsDir

private boolean setFitsDir(String dir)
                    throws IOException

Sets the fits directory.

Throws:

IOException

private String getFitsDir()
                   throws IOException

Get current FITS file output directory.

Returns:

the current FITS file output directory.

Throws:

IOException

setIncrementing

public boolean setIncrementing(boolean set)
                        throws IOException

Set the increment status parameter: true = increments a file number for storing all fits files, false = overwriting of existing files. This means if increment = 1: the fits filename is concatenated from base name + number + extension. Example basename = "bias" number = "00657" extension = ".fits" result bias-00657.fits, next file will be bias-00658.fits etc.

WARNING: There is no way to query TF's server for the true fits name, thus setting this option may result in image trace lost. If this is not what is intended, a partial workaround is to reset the internal counter in TF guider_server.c, called BaseFn in each call to the set_increment_1_svc method (which would be a good idea anyhow). This allows tracing of the fits extension, but only, if no fits file with this extension already exists.

Parameters:

set - boolean to set the incrementing facility.

Throws:

IOException

isIncrementing

public boolean isIncrementing()
                       throws IOException

Get the increment status.

Returns:

the current incrementing status.

Throws:

IOException
