Class SesAccess

java.lang.Object

util.CommandLineParser

stella.rmi.GenericAccess

stella.ccd.CameraAccess

stella.ccd.SesAccess

public class SesAccess
extends CameraAccess

A small program allowing access to SesControlling enhanced objects. The command line arguments are scanned for recognized switches and processed accordingly. Additionally to the functionality of the parent class ShiftListener, this class supports the following switches:

• -a: Enables automatic ccd control. If the ccd is actually controlled by a non-automatic command caster, e.g. a stella.jview.JLaunchBox, this caster should be deregistered before enabling automatic mode. In automatic mode, only the status retrieval and setting the manual mode is supported.
• -m: Disables automatic roof control, i.e. shifts to a manual mode. Control with a non-automatic command caster, e.g. a stella.jview.JLaunchBox, requires additionally a registering at the new caster. Only in manual mode, all of the further actions are allowed.
• -aExp: Aborts the current exposure. The data retrieved so far is stored in the provided fits file.
• -bExp: Takes a bias exposure. The data retrieved is stored in the provided fits file.
• -dExp: Takes a dark exposure. The data retrieved is stored in the provided fits file. The second paramter gives the exposure time.
• -sExp: Takes a science exposure. The data retrieved is stored in the provided fits file. The second paramter gives the exposure time.
• -ff: Sets the camera to full frame.
• -g: Sets the image geometry. The parameters provided give the x-offset, y-offset, x-size, y-size, x-binning factor, and the y-binning factor, respectively.
• -k: Adds the fits key with the given name. The second paramter points to the name of the parameter to which this key should map. The third parameter is a comment.
• -r: Removes the fits key with the given name.
• -s: Returns the status of the ccd camera.
• -q: Quits the building controling instance.

Method Detail

processSwitches

protected boolean processSwitches(Remote listener)
                           throws RemoteException

Process the command line switches found. If the remote reference handed over is a SesControlling and one of the switches defined in CameraAccess.ZEROSWITCHES, CameraAccess.ONESWITCHES, TWOSWITCHES,THREESWITCHES, or SIXSWITCHES is given, the appropriate method of the listener control is called. Note that the command line must be parsed before calling this method.
Implementation note: Prior to the new command line switches, the one provided by the parent class are processed.

Overrides:

processSwitches in class CameraAccess

Returns:

True on success.

Throws:

RemoteException
